Humans are noisy. The National Park Service estimates that all of our whirring, grinding, and revving machines are doubling or even tripling global noise pollution every 30 years. 

A lot of that noise is negatively affecting wildlife and human health. Maybe that’s why we’re so consumed with managing our sonic environments, with noise-cancelling headphones and white noise machines — and sometimes, we get into spats with our neighbors, as one of our guests did…

So for this episode, producer Jeongyoon Han takes us on an exploration of three sonic landscapes: noise, silence, and something in between. 

Featuring Rachel Buxton, Jim Connell, Stan Ellis, Mercede Erfanian, Nora Ma, and Rob Steadman.

This episode originally aired  in July, 2023.
