Help Scientists Record One Day of Sound on Earth

Bryan Pijanowski wants to capture the sounds of the world on a single day, and he needs your help. On Earth Day, April 22, Pijanowski hopes to enlist thousands of people in recording a few minutes of their everyday surroundings with his Soundscape Recorder smartphone app. All those sonic snippets could create an unprecedented soundtrack to life on Earth — and as they accumulate, year after year, scientists could use them to measure patterns and changes in our sonic environments.

"I've been on a campaign to record as many ecosystems as possible," said Pijanowski, a soundscape ecologist at Purdue University. "But there's only so many places in the world I can be. I thought about how I could get more recordings into a database, and it occurred to me: We have a couple billion people on this planet with smartphones!"
