Some sounds are like rug burn for your ears, while others are pleasant and soothing. We explore these sounds and get to the bottom of why we might interpret them as “good” or “bad”. Featuring Tommy Edison and David Poeppel. Twenty Thousand Hertz is hosted by Dallas Taylor and produced out of the studios of Defacto Sound.Consider supporting the show at donate.20k.orgEpisode transcript, music, and credits can be found here.
