Mysterious noise irking Tampa residents may be fish mating loudly: 'Pretty uncommon phenomenon' - New York Post

Residents of Tampa, Florida have reported hearing strange noises coming from the bay for years, and now scientists believe it may be fish mating — very loudly, according to reports.

The deep, vibrating sound has been plaguing residents since at least 2021, prompting several calls to police, according to WTVT. But the most unnerving aspect has been not knowing the source of the racket

Local scientist James Locascio was tasked with getting to the bottom of the mystery, and has identified the sound as black drum fish mating underwater.

“This is a pretty uncommon phenomenon,” Locascio told The Washington Post. “All these people are surprised by it because it’s not well known.”

Residents had long speculated the origins of the sound before they enlisted Locascio, who agreed to investigate if they could cover the costs for recording.

They launched a GoFundMe campaign to raise money for a study.

“It seemed a little bit silly for me to be pursuing this so doggedly,” Sara Healy, the fundraiser’s organizer, told WaPo. “But on the other level, this is something that’s important to the community.”

Locascio, a fisheries program manager for the Mote Marine Laboratory and Aquarium in Sarasota, said he plans to place the equipment underwater to confirm his hypothesis.

“It’s a low frequency sound, and so they travel much better and go further distances, and they go through dissimilar media more efficiently,” he told WVTV.

The mating sound travels through the ground, possibly explaining how residents living more than a mile from the water can still hear it, he explained.

Black drum fish produce the bass-like sound by moving their muscles against their swim bladder, Locascio told the Washington Post.

The scientist completed his dissertation on the black drum fish in 2005 at the University of South Florida College of Marine Science. He used his underwater acoustic recordings to help solve a similar sound mystery for residents in Cape Coral and Punta Gorda — about 100 miles south of Tampa.

Around this time last year,  Punta Gorda officials confirmed to residents a strange sound many had reported was coming from black drum fish “during spawning season,” in the city’s canals, the Miami Herald reported.

Florida’s mystery bass rumble may be sound of frisky fish mating - The Guardian

A strange noise that for years has been bothering residents of Florida could actually be the sound of fish mating – loudly.

Residents of a neighborhood in Tampa, Florida, have been frustrated by a mysterious bass sound in their surroundings, the Washington Post reported.

And they have learned the mating process for black drum fish – a species living off the Atlantic coast – could be responsible for all the racket, according to a local scientist who was enlisted to find the sound’s source, the Post reported.

“This is a pretty uncommon phenomenon,” scientist James Locascio said to the Post. “All these people are surprised by it because it’s not well known.”

The deep sound, sometimes accompanied by a low vibration, has bothered neighbors since 2021 and triggered noise complaints to local police, WTVT reported.

For years, local residents were unable to pinpoint what was causing the noise, with some theorizing that a party boat, secret military base or even aliens were to blame.

The intermittent noise ultimately bothered neighbors so much that they reached out to Locascio, who agreed to help if residents could cover the cost of recording equipment for the investigation.

It took about a week for local residents to raise more than $2,500 for the equipment Locascio required.

“It seemed a little bit silly for me to be pursuing this so doggedly,” Sara Healy, the fundraiser’s organizer, said to the Post. “But on the other level, this is something that’s important to the community.”

With the money raised, Locascio – who works as a fisheries program manager for the Mote Marine Laboratory and Aquarium in Sarasota, Florida – plans to place microphones underwater to determine exactly where the sound is coming from.

Locascio told WTVT that the mating sound of the black drum fish travels through the ground, explaining how residents living miles from the water can still hear it.

Black drum fish produce the bass-like sound by moving their muscles against their swim bladder, Locascio said to the Post.

While some neighbors are hesitant to accept Locascio’s theory, all agree that it has been irritating to not know the source of the sound.

“You’re really spending all this time questioning your sanity,” Stephanie Kaltenbaugh said to the Post as she discussed not knowing from where the sound was coming.

Similar noises have been heard in other coastal cities in Florida. Last year, residents of Punta Gorda – about 100 miles south of Tampa – reported almost identical vibrations.

Punta Gorda government officials told concerned residents in a Facebook post that the sound was coming from black drum fish “during spawning season”, the Miami Herald reported.

“Punta Gorda residents living along canals frequently hear black drum calls in their homes during the spawning season,” the Facebook post said.

“This is possible because the low frequencies of these calls are able to travel through the ground and into the walls and floors of homes.”

Is The Speed Of Sound On Mars The Same As On Earth? - IFLScience

The speed of light in a vacuum is the same wherever you measure it in the universe, according to Einstein's special theory of relativity. Whether you're sat on Earth, Mars, or Zoozve, if you measure the speed of light you'll find it chugging along at a cool 299,792,458 meters per second (983,571,056.43 feet per second), the absolute speed limit of the universe.

Sound is not the same as light. As the poster for Alien explains, in space no-one can hear you scream. Or to put it another way which won't sell as many movie tickets, sound cannot travel through a vacuum because it is a vibration propagating as an acoustic wave through a medium, be it liquid, solid, or gas. 

Sound moves at different speeds through those mediums, traveling faster at through greater densities. On Earth, sound moves at 1,500 meters (5,000 feet) per second in water, and in air around 340 meters (1,115 feet) per second. In solids, sound moves much faster, though how fast depends on the solid. Scientists attempting to calculate the fastest that sound could possibly travel found that it decreases with the mass of the atom, implying that sound would be fastest if it were to propagate through solid hydrogen. Though solid hydrogen only occurs at astonishingly high pressures like those found inside gas giants like Jupiter, they calculated that sound would move along at 36 kilometers per second (22 miles per second) in it, likely the fastest possible speed that sound can travel.

This leads us to answer the question in the title of this article. Earth's atmosphere is much thicker than Mars', being roughly 100 times more dense on our planet's surface than on the red one. As such you'd expect sound to travel slower there than here, if the atmosphere is thick enough to carry sound any significant distance at all.

Of course, we have recordings of sound on Mars, including that of a Martian dust devil, thanks to the army of robots we have sent there. So we know that sound travels there experimentally.

In fact, Mars is one of only two planets where we have actually measured the speed of sound. In an experiment in 2022, NASA's Perseverance rover fired lasers at rocks and waited for the resulting shockwave to be heard by its microphones. Just like on Earth, the speed of sound varies depending on temperature and altitude, but experiments conducted by the rover found that the speed of sound in the Jezero Crater averaged out to around 240 meters per second (540 miles per hour).

As day changes to night on Mars, the speed was found to vary by around 10 percent, because of the resulting drop in temperature. Sound on Mars doesn't stop being weird there though. Due to how sound travels through carbon dioxide at low pressure, Mars goes through a change in the speed of sound in the audible bandwidth. 

"For an acoustic wave with a frequency higher than ~240 Hz [just below middle C on a piano], CO2 vibrational modes activated through collisions do not have time to relax their energy," the team explained in their paper. "It turns out that, on Mars, frequencies above 240 Hz travel more than 10 m/s faster than low frequencies. It may induce a unique listening experience on Mars with an early arrival of high-pitched sounds compared to bass."

Sound-powered sensors stand to save millions of batteries - Tech Xplore

Sound-powered sensors stand to save millions of batteries
The prototype of the sound sensor is relatively large. Credit: Astrid Robertsson / ETH Zurich)

Sensors that monitor infrastructure, such as bridges or buildings, or are used in medical devices, such as prostheses for the deaf, require a constant supply of power. The energy for this usually comes from batteries, which are replaced as soon as they are empty. This creates a huge waste problem. An EU study forecasts that in 2025, 78 million batteries will end up in the rubbish every day.

A new type of mechanical sensor, developed by researchers led by Marc Serra-Garcia and ETH geophysics professor Johan Robertsson, could now provide a remedy. Its creators have already applied for a patent for their invention and have now presented the principle in the journal Advanced Functional Materials.

Certain sound waves cause the sensor to vibrate

"The sensor works purely mechanically and doesn't require an external energy source. It simply utilizes the contained in ," Robertsson says.

Whenever a certain word is spoken or a particular tone or noise is generated, the sound waves emitted—and only these—cause the sensor to vibrate. This energy is then sufficient to generate a tiny electrical pulse that switches on an electronic device that has been switched off.

The prototype that the researchers developed in Robertsson's lab at the Switzerland Innovation Park Zurich in Dübendorf has already been patented. It can distinguish between the spoken words "three" and "four." Because the word "four" has more sound energy that resonates with the sensor compared to the word "three," it causes the sensor to vibrate, whereas "three" does not. That means the word "four" could switch on a device or trigger further processes. Nothing would happen with "three."

Newer variants of the sensor should be able to distinguish between up to twelve different words, such as standard machine commands like "on," "off," "up" and "down." Compared to the palm-sized prototype, the new versions are also much smaller—about the size of a thumbnail—and the researchers are aiming to miniaturize them further.

Metamaterial without problematic substances

The sensor is what is known as a metamaterial: It's not the material used that gives the sensor its special properties, but rather the structure. "Our sensor consists purely of silicone and contains neither nor any , as conventional electronic sensors do," Serra-Garcia says.

The sensor comprises dozens of identical or similarly structured plates that are connected to each other via tiny bars. These connecting bars act like springs. The researchers used computer modeling and algorithms to develop the special design of these microstructured plates and work out how to attach them to each other. It is the springs that determine whether or not a particular sound source sets the sensor in motion.

Monitoring infrastructure

Potential use cases for these battery-free sensors include earthquake or building monitoring. They could, for example, register when a building develops a crack that has the right sound or wave energy.

There is also interest in battery-free sensors for monitoring decommissioned oil wells. Gas can escape from leaks in boreholes, producing a characteristic hissing sound. Such a mechanical sensor could detect this hissing and trigger an alarm without constantly consuming electricity—making it far cheaper and requiring much less maintenance.

Sensor for medical implants

Serra-Garcia also sees applications in , such as cochlear implants. These prostheses for the deaf require a permanent for signal processing from batteries. Their power supply is located behind the ear, where there is no room for large battery packs. That means the wearers of such devices must replace the batteries every twelve hours. The novel sensors could also be used for the continuous measurement of eye pressure. "There isn't enough space in the eye for a sensor with a battery," he says.

"There's a great deal of interest in zero-energy sensors in industry, too," Serra-Garcia adds. He no longer works at ETH but at AMOLF, a public research institute in the Netherlands, where he and his team are refining the mechanical . Their aim is to launch a solid prototype by 2027. "If we haven't managed to attract anyone's interest by then, we might found our own start-up."

New Study Using Sound Reveals Secrets of Ancient Sanctuary of Zeus - GreekReporter.com - Greek Reporter

A new study which uses a novel technique to understand how sounds were perceived by ancient humans claims to have uncovered secrets at the Sanctuary of Zeus on Mount Lykaion in Greece.

The newly published study explores the movement of sound within the Sanctuary of Zeus using a recently-developed technique called psychoacoustics, detailing how sounds interacting among different structures can provide an idea of their original purpose.

Published in the journal Open Archaeology, Pamela Jordan from the University of Amsterdam led the study at the Sanctuary of Zeus with the goal of gathering insight into how the site may have been used by ancient visitors.

“If you use sound as the basic frame, you inherently start from a place of connection and a place of interrelation between portions of the site,” Jordan told SciTechDaily.

How the Study Used Sound to Detect Secrets of Sanctuary of Zeus

The study consisted of Jordan and her team with over four recording sessions between 2015 and 2022. Pre-recorded sounds ranging from white noise to speeches at different points at the site were played.

These sounds were recorded using two microphones placed in close proximity to mimic human ears, known as binaural recording. The team then employed a range of digital tools to help evaluate the sound frequency and clarity experienced at various points.

More than 1,600 recordings were made in total in 2022, allowing the research team to analyze lots of sound relationships at a bunch of points throughout the sanctuary. Jordan noted that other researchers had said sounds from the site’s hippodrome could easily be heard from a hillside to the west. Taking this into consideration, Jordan’s team recordings did show that the hippodrome’s surface reflected sound to both the audience in the arena and those who may have gathered on the hillside.

This showed the hillside could have acted as an important viewing position. Switching the speakers and microphone positions further revealed sounds from the hillside could be heard in the hippodrome at the Sanctuary of Zeus.

The study concludes, “Sonic investigations on Mount Lykaion have made one thing clear: sound can be an organizing force to human interaction on the mountain. Applying psychoacoustic approaches to archaeological examinations here enables new kinds of queries concerning how sounded events were perceived in the past by listeners, in addition to how architecture or landscape may have harbored sonic experience.”

Based on the study report, “a primary question guiding work on Mount Lykaion is whether the placement of architectural structures took advantage of latent acoustics in the landscape for ritual practice. The evidence is not yet sufficient to say definitively that sonic effect was an intentional driver of the sanctuary’s (standing) architectural design.”

“However,” according to the study, “the findings substantiate where and to what degree sound could have played a central role in visitor experience. Sonic connectivity between distant people and their activities would have been a prevailing feature in stationary positions.”

What Seattle stands to lose if Theatre Puget Sound doesn't make it - The Seattle Times

Arts Spotlight

Last September, an alarming email dinged in my inbox. The message came from Crystal Yingling, a veteran theater administrator and current executive director of Theatre Puget Sound, the 27-year-old organization whose raison d’être is supporting local theaters and theater artists.

“If we make it through the end of this year,” Yingling wrote, “it will be a miracle.” 

When Yingling and I checked in in December, a miracle had happened, albeit a small one: TPS would survive through the end of the year, Yingling said (largely thanks to cutting hours across the small staff, starting with herself) but only had a financial runway to survive through April 2024. That timeline was still true as of late January, but Yingling and the TPS team are throwing everything at the wall and steering hard into the organization’s value as a community resource to try and keep TPS afloat.

Making theater in 2024’s culture and economy is hard enough, and anything that makes it harder — including possibly losing TPS, with its mission “to foster and advocate for a robust and equitable theater community” — would be, in my very professionally expressed opinion, a staggering bummer. 

What is Theatre Puget Sound? Among its chief functions, TPS presents The Gregory Awards, which annually (with the exception of a few COVID years) honors shows and artists in the region; its website hosts job and audition postings, show listings, and other points of peer-to-peer connection; and it runs the unified general auditions, where TPS member actors can audition for representatives from many different theaters at once.

Also, TPS’ Space 4 Arts program administers around 25,000 square feet of theater rental space in Seattle Center’s Armory building, where the organization is headquartered, including storage space, several rehearsal spaces, and three performance spaces including the Center Theatre, the current production home to Seattle Shakespeare Company and, until June 2023, Book-It Repertory Theatre. 

TPS, Yingling said, relies on membership dues from individuals and member theaters to sustain operations, and membership tanked during COVID as closed theaters meant little need for auditions or awards. 

Then, Book-It’s sudden closure ripped a financial hole in TPS’ already-tenuous bottom line — some $25,000 in planned revenue vanished overnight, Yingling said. 

While providing affordable space rentals is an important way TPS supports local artists, those rental fees, Yingling said, haven’t kept pace with even the baseline cost of operating them, a problem exacerbated by the fact that TPS shares all rental revenue evenly with Seattle Center.

“My main goal is to try to update and reinvent this model into something that can be sustainable,” Yingling said. 

As part of this new mission-driven model, three theater companies — Sound Theatre Company, Latitude Theatre and Parley Productions — have just been announced as TPS resident companies, which will guarantee TPS some rental revenue and guarantee the theater companies affordable rehearsal and performance spaces, marketing partnerships and other shared resources. 

Yingling is also hopeful that a new, more favorable agreement can be reached with Seattle Center for the rental venues; if signed by April, that would buy TPS a little more time to increase revenue.

Currently, TPS has around 800 paying individual members, and some 100 member theaters of varying sizes, Yingling said, which is “nearing pre-pandemic membership numbers but not pre-pandemic revenue.” Thousands more users availed themselves of the COVID-era, pay-what-you-want membership option, Yingling said. That option is no longer available (though TPS remains committed to financial accessibility via tiered price points and scholarships for those who need them) but membership revenue is less than half of what it was in 2019 and costs have increased significantly since then.

“We’re trying to get back to the most successful years of TPS when the membership base was higher,” Yingling said. “And ensuring that we have enough value that people want to come back, that it’s useful, and that we’re helping to foster an environment of shared knowledge and resources and learning.”

Enter: TORCH, the Theater Online Resource and Community Hub, currently slated to debut in late April. (“The irony of ‘if we will make it until then’ is not lost on me,” Yingling wrote in a follow-up email. “But TORCH will remain available for membership use regardless.”)

TORCH, which will ultimately replace TPS’ current website, will include features like discussion boards, trainings and resources, job and audition listings, a searchable database of industry professionals and access to revenue- and cost-sharing opportunities such as shared concessions or staff.

So many small theaters are grappling with the same problems, Yingling said, and she hopes TPS can help them share resources for everything from marketing to hiring front-of-house staff. As Yingling put it, “One company can spend $100,000 on some lighting or five companies can spend $100,000 on some lighting, which makes more sense?”

Also on the horizon are the next unified general auditions and a subsequent design and tech fair, which all kicks off Feb. 26, giving local performers and playwrights, designers and technicians a chance to connect with theaters from around the region, and vice versa. 

An arts reporter’s job can sometimes feel like that of a nature documentarian: You’re not supposed to intervene even when a wonderful creature gets ripped to shreds by an unforeseen predator. But how can (or should) the media deal with such a problem? Where does industry news become publicly interesting, and can the degradation of infrastructure (often boring, very important!) reach a newsworthy threshold before the headline reads: “RIP, TPS?” 

Seattle theater won’t come crumbling down if TPS ceases to exist, sure. But strong arts ecosystems need artists at all career stages, along with rehearsal spaces where they can work, small spaces where they can experiment, midsize spaces where they can learn, and large theaters where they can make a living, as a bare minimum. The more of those artists and spaces we can support, the better. 

Yingling’s hopes are high that TPS will be able to continue helping all those creatives to create, but, she said, “It doesn’t just happen magically on its own, unfortunately. It takes a lot of work and resources.”

Marshall Motif II ANC Review: Stellar Sound, Classic Style - Outside

The story goes that in the early 1960s, John Entwistle, bassist for The Who, couldn’t hear his instrument over the clamorous drums of his maniac bandmate, Keith Moon, so he asked London drum shop owner Jim Marshall to build him a louder amplifier. This resulted in guitarist Pete Townshend needing a louder amp from Marshall so he could hear his guitar over Entwistle’s bass—and thus was Marshall able to go into business making history’s most beloved amps.

Sixty years later, the Marshall company has smartly reapplied its rich pedigree, bringing its engineering know-how to today’s consumers by producing (in conjunction with Zound Industries) a stellar line of headphones, earbuds, and Bluetooth speakers, like the Emberton II, the best speaker in our roundup last year).

This year our attention was captured by Marshall’s Motif II ANC true wireless earbuds, which in shape and size are very similar to Apple’s AirPods Pro, except they’re all decked out in black, the Darth Vader to Apple’s Stormtrooper.

The Apple-pioneered stem design has found its way into lots of other companies’ offerings, which testifies to how the design, despite looking clunky, manages to stay firmly lodged in your ears, through some kind of ergonomic alchemy, during most basic activities. The stem also makes for a nice place to grab onto them, which, if you’re a big-handed person on a cold day, can make smaller, rounder earbuds a pain in the ear.

The Motif II ANCs, however, one-up Apple by adding textured plastic on their stems (with an attractive gold touch on the tip), which makes them even more grippable and seems to help hold them in place while you’re wearing them—something our testers universally appreciated. On the outside of each earbud is a touch control that allows you to pause, skip tracks, turn on active noise cancellation (ANC), and employ Spotify Tap, which lets subscribers play from the music service without opening their phone.

As for the ANC in its name, while their noise canceling is not as robust as Apple’s, Marshall’s earbuds did a pretty good job of blocking out wind while running and loud talkers in cafés (though no amount of ANC would be enough to cope with Keith Moon). They also have IPX5 ingress protection, meaning they’re not rated for their ability to keep out dust and solids but will do fine with heavy rain, sweat, or sea spray. One tester found that they needed occasional fit adjustment during runs, though it’s worth noting that they weigh less than the AirPods Pro—at 4.3 grams per bud, compared with Apple’s 5.3 grams.

But design isn’t what made these our favorites. Listening to our favorite tracks on the Motif II ANC was a consistently pleasant experience. Where some brands use artificial bass boosting or other gimmicks to make it feel like you’re at a rave at 4 a.m., these delivered clear, faithful highs, mids, and lows—producing more of a sense of sitting inside a sealed-off recording studio, hearing every note and nuance. Should bass really be important to you, that can still be achieved by downloading Marshall’s app and playing around with its equalizer. More versatile than the typical companion app, Marshall’s lets you dial in exactly the balance you like, and you can even program multiple EQ settings and then use the touch control to shift among them.

Marshall also nailed the design of the charging case. Made from 70 percent recycled plastic, the case’s textured vinyl surface evokes the classic Marshall amp stacks, and it’s built tough—we’ve dropped it and sat on it and it didn’t crack. The case gives you four charges of six hours each, in addition to the six hours of initial playing time you’ll get in the buds with ANC turned on (or nine hours without). This is about average: in line with the AirPods Pro but two to three hours less than competitors like Sony, Sennheiser, and JLabs.

The Motifs were our 2024 pick for Best All-Around earbuds, for their build quality, consistently impressive audio, everyday versatility, and sheer character. Our Gear Guide testing team spent some 35 hours with them, happily grabbing them when heading out on runs, hikes, ski tours, and cross-country travel, and they also performed admirably when making phone calls, washing the car, and tinkering in the workshop. With what one tester called the “best sound quality of all the buds in this test” and a design that made everyone take notice, they’re a prime example of the state of the art of Bluetooth earbuds today.

New, quieter Pickleball equipment takes a swing at the sport’s noise problem - The Mercury News

PIEDMONT — The “pop, pop, pop” that’s become synonymous with Pickleball may soon be a racket of the past.

At least, that’s the lofty goal promised by a new generation of equipment and technology specifically developed to lessen the frequency, pitch and overall acoustic burden of the booming sport.

Rather than listening to plastic-y staccato “thwacks,” imagine slightly padded “thumps” when paddles and balls collide.

News of this emerging gear could be music to non-players’ ears, especially as the fast-growing sport has sparked neighborhood clashes and legal battles in recent years; complaints have popped up in Berkeley, San FranciscoLos Altos, Menlo Park, Walnut Creek and across the Bay Area, but residents and elected officials have continually struggled to craft solutions that resolve Pickleball’s cacophonous soundtrack without shutting down the sport altogether.

Carl Schmits, managing director of facilities development and equipment standards for USA Pickleball, said that as tennis courts, basketball courts and other spaces in community parks were rapidly converted to try and meet the demand of Pickleball players across the Bay Area, many of those changes happened without much research into how the game might increase the amount of noise and number of people in those spaces.

Schmits said that’s why Pickleball USA has been researching and investing in solutions with acoustic engineering firms for the past 18 months — aiming to change the actual sound of the game, and also help local communities understand how to best study and improve the acoustics of existing facilities before installing additional courts.

On Wednesday, he demonstrated a handful of new equipment specifically designed for quieter play at Piedmont’s Linda Beach Pickleball Courts. That location was fitting, since players are already required — or at least encouraged — to only use equipment that’s been certified in USA Pickleball’s newly launched “Quiet Category” of products. Piedmont officials have even printed out a color-coded list of acceptable paddles and balls to use at Linda Beach.

Generally speaking, Schmits said “quiet” certified paddles can reduce the sound of contact from 90 decibels — roughly the volume of hairdryers and power tools — down to only 80 decibels, which is closer to the noise levels measured on a busy downtown street or near a garbage disposal. He said this new generation of gear also aims to lower the pitch of the ball “pops,” which can negatively impact players’ hearing.

Since the launch of the first quiet paddles by OWL Sport in November, Schmits said it’s possible to cut the acoustic signature of the sport in half, especially when combined with other interventions, such as fabric sheaths that cover louder paddles and sound-absorbing panels designed with innovative nanofiber carbon fibers and polymer cores that can be installed along fences around Pickleball courts.

“It’s a difficult engineering challenge to squeeze any more noise out,” Schmits said, explaining why Pickleball USA is also researching ways that A.I. and other technologies can help assess and monitor the din of gameplay. “But this new category (of quieter products) that we created will help address very sensitive situations.”

Eliot Arnold, founder and CEO of SLN/CR — a Kansas City-based startup that produces sound-absorbing panels — emphasized that in addition to the physical equipment being manufactured, objective data and real-time awareness of the soundscape around Pickleball courts will be vital to the sport’s ongoing innovation, as well as its ability to address issues proactively.

“As the sport grows, there’s going to be more need to collect information and analyze information — not just going off people’s opinions,” Arnold said. “Instead of having a neighbor call (about noise), can we build a system that alerts the community, law enforcement or Parks and Rec.?”

Justin Long, director of the city of Alameda’s Recreation and Park Department, is one of many city administrators who are increasingly trying to find new tools and data to understand — let alone mitigate — just how much noise Pickleball games create.

Since it’s often difficult to isolate which activities and people are contributing to noise complaints, he said information from product research and acoustic baseline studies will make it easier for local decision-makers to balance the perspectives of both Pickleball players and neighbors living near their courts.

“(This kind of data is) helping us navigate the conversation between opposing sides,” Long said Wednesday. “We want to make sure that we’re providing activities for everyone in the community, but how do you balance such opposing forces? It invites conflict because in every city, land is a premium. We can’t just expand every sport.”

Even though this new type of equipment may present additional challenges down the line — especially since new gear can often be more expensive and inaccessible, he supports any additional resources that civic leaders like him can use to be good stewards for everybody.

“The good thing is that the dialogues are happening,” Long said. “It doesn’t need to happen in court.”

The Martin County Sheriff’s Office is crediting the bravery of a 17-year-old girl for helping them make a quick arrest of the man they say assaulted her.

Deputies from Martin and Palm Beach Counties arrested 42-year-old Antonio Amaya-Guevara Friday night and charged him with occupied burglary, battery, robbery by sudden snatching, and child abuse.

Investigators said Amaya-Guevara kicked in the back door of a home on SE Alamanda Way Friday afternoon and assaulted the 17-year-old girl who lived there.

“This is alarming to us,” said Martin County Chief Deputy John Budensiek. “It’s a 17-year-old girl.”

Budensiek said the girl was alone in the home, sitting in her bedroom, when she heard a noise.

“The noise prompted her to come out of her room and encounter a Hispanic-speaking male in her living room rummaging through drawers,” Budensiek said.

Budensiek said the girl immediately called her father and started arguing with the stranger, telling him to leave.

The man eventually left, but Budensiek said the girl didn’t just let him go.

He said the girl followed the suspect down the street, around the corner, and down the next street, taking photos and videos of him.

Suicide Squad Devs Lay Out Battle Pass, Endgame Plans And They Sound…Good? - Kotaku

A close up shows Captain Boomerang making a very confused face.

Rocksteady developers behind the upcoming Suicide Squad: Kill The Justice League—a DC villain-themed open-world co-op looter shooter—revealed some new details and thoughts behind the game’s battle pass, seasons, and endgame content. And while it’s still a live-service game that will likely have its own issues come launch, I’m feeling optimistic about it based on these recent answers that, at least on paper, sound good.

First revealed back in 2020, Suicide Squad is the next game from Rocksteady, the devs behind the earlier Batman: Arkham games. And while this new shooter is set in that same universe, since its reveal, fans haven’t been terribly excited about the game. Whenever we see more of it—via trailers or leaks—it looks a lot like a live-service shooter, even if Rocksteady is unwilling to admit that. Mixed previews earlier this month didn’t help win over folks, either. However, in a recent Discord Q&A, the devs laid out their plans for Suicide Squad’s endgame and seasons, suggesting that this game is fully playable solo and won’t make you grind for weeks to play limited-time content.

On January 26, over in the official Suicide Squad Discord server, the devs held a second Q&A after the previous one was so well received. This time around, many of the chosen community questions and developer answers seemed focused on convincing folks that this game won’t demand you treat it like a second job.

“We all love playing games, but we also have lives,” said Axel Rydby, Game Director on Suicide Squad.

“That’s been a big part of our design philosophy making this game. We don’t want the game to feel like a life commitment or be a game where you have to sacrifice a lot to see all the content on offer, or feel like you’re not making good progress in the game if you can’t play hundreds of hours,” explained Rybdy.

A good example of this is that seasonal battle passes—which Rocksteady reminded folks multiple times in Discord only contain cosmetics—and all the content that is added to the game with each new season, can be done at any time. All that stuff, like battle-pass-exclusive outfits, new locations, missions, and the game’s first new playable character, The Joker, will not leave the game once the season is over. According to Rocksteady, you can always go back and make progress in a battle pass from a previous season or even buy the premium version well after its release.

“We believe that our team has created some of the best-looking cosmetic items ever,” added Darius Sadeghian, studio director at Rocksteady. “We want those to be available for our players to enjoy without fear that they’ll miss out on anything.”

As someone who plays a lot of Fortnite, a game that is built on battle pass FOMO and limited-time items in its ever-rotating store, this sounds very nice.

You can play all of Suicide Squad solo

Another example of Rocksteady claiming the game will respect your time and not demand you spend every day playing it is that every mission and activity in the game, even the toughest endgame content, can be completed solo. This, Rydby pointed out, is part of the studio’s philosophy when developing the co-op game.

“We want this game to be generous, both with your time and with all the features we have to offer,” said Rybdy.

Adding to this, Rocksteady confirmed in today’s Discord Q&A that you will be able to go back and replay any and all missions from the game’s story. And if you play with friends, and move past your current point in your own game, the devs say you’ll be able to skip those sections when you hop back into your solo world. Another example of the team trying to respect players’ time, which I appreciate.

Of course, just because a game has great endgame and season pass plans, doesn’t mean it will be good. If Suicide Squad’s combat is bad, its traversal gameplay clunky, and/or its narrative boring, it won’t matter how nice the season’s cosmetics are or how generous the battle pass might be; people will stop playing.

We don’t have to wait long to see if the game will be fun enough to invest any time into future seasons, characters, or more, since Suicide Squad: Kill the Justice League launches on Xbox Series X/S, PS5, and PC on February 2, 2024. If you pay the publisher-created ransom fee and pre-order the deluxe edition, you can play three days earlier.

'Happy wherever you sit': Obsolete sound system replaced at Genesee Theatre in Waukegan - Daily Herald

A big change at the Genesee Theatre in downtown Waukegan has to be heard rather than seen.

Better clarity, coverage and dynamics are among the elements of a new sound system representing a powerful upgrade from the previous one installed in 2004.

“Technology has come a long way since 2004,” said Mack Folkert, the theater’s production manager. “So far, it's been all really positive reviews, from artists and touring engineers (who) are very impressed with it.”

Folkert said the 2004 system by Meyer Sound Laboratories was designed to be used primarily for musicals, speaking engagements and films.

“For concerts, we were frequently renting speakers to meet artists' requirements,” he explained.

Considered top of the line for its time, the old system was obsolete and needed to be replaced. With 40 speakers, six sub-woofers and two new digital audio consoles replacing the single original analog console, the Meyer PANTHER system is a substantial upgrade, operators say.

“You won't find a better sound,” General Manager Dennis Sheen said. “You are going to be happy wherever you sit.”

A new sound system recently was installed at the Genesee Theatre in Waukegan. Theater officials say its been getting rave reviews from performers and audiences. Courtesy of Genesee Theatre

According to the company, the PANTHER-based system was installed across a range of venues last year, from clubs to arenas, including the Fillmore in San Francisco and the new Mohegan INSPIRE Entertainment Resort in South Korea. It powered a variety of tours, including those of Ed Sheeran, John Mayer and Metallica, among others.

According to Folkert, the new energy efficient system produces more sound with a lot of “headroom,” meaning the speakers never have to be used at 100% power. It has fewer speakers but much more power overall, and is a system that would work in a much larger auditorium than the 2,403-seat Genessee, he added.

“When you have higher quality sound you don't need to drive it as hard for it to sound good,” Folkert said. “It sounds louder because it's so much fuller and better.”

The result is a better listening experience including beneath the balcony, he added.

Theater officials declined to disclose the cost of the new system, which debuted in December, except to say it was a substantial investment.

“We spared no dollar,” Sheen said. “The performers love it, the customers love it.”

The Genesee opened in 1927. It is owned by the city of Waukegan and managed by the nonprofit Friends of Genesee Theatre

Upcoming acts include the touring Broadway production of Jesus Christ Superstar on Feb. 16, Peter Frampton on March 30, and Kansas on April 13. Visit geneseetheatre.com/events.
