In this episode, we’re taking your questions on the subject of sound. We talk about tinnitus, “the mind’s ear,” and the celebrity voices we have strong feelings about, from Bob Ross to President Obama, Michael Barbaro to Ira Glass. So strap your earbuds in, we’re going for a ride! What are tintinnabula, and the first wind chimes in the world? What exactly is ASMR, and what makes it feel good? Why does my cat make twitter sounds when she sees birds? Why do frogs sing together around the same tiny pond? If a tree falls in the woods, and no one is around to hear it, does it make a sound? Does the environment influence the evolution of a language? If we have a “mind’s eye” do we have a “mind’s ear?” What’s tinnitus? Featuring Ilija Dankovic, Craig Richard, Alejandro Vélez, Seán Roberts, Sarah Theodoroff, and Tara Zaugg. For full credits and transcript, visit outsideinradio.org.
