Audio recorders in treetops are powered with solar panels. One aspect of the SAFE Acoustics Project is to monitor ecosystem health through sound. SAFE Acoustics
On a rapidly changing planet, there are many ways to measure the health of an ecosystem. Can sound be one of them?
In today's episode, NPR Short Wave reporter Emily Kwong dives into a new methodology that applies machine learning technology to audio soundscape recordings. Lead researcher Sarab Sethi explains how this method could be used to predict ecosystem health around the world and detect anomalous sounds caused by human action, from logging to poaching to the ecological impacts of climate change.
