What is the oldest recorded sound in history? For over 100 years researchers thought they knew until a mind-blowing discovery by historians found something new - and technological advances allowed it to be played back for the first time in history. What is the oldest recording of a musical performance, president, battlefield, television broadcast, cell phone call, and more? Featuring Patrick Feaster, co-founder of FirstSounds.org, three-time Grammy nominee, and Ph.D. in Musicology as well as Lynn Novick, award-winning filmmaker, and co-directing partner of Ken Burns. 
Twenty Thousand Hertz is produced out of the studios of Defacto Sound and hosted by Dallas Taylor.

Hans Zimmer's Remote Control

All over the world, there are unique and breathtaking sounds that you can only hear in one specific place. In this episode, we travel to two of the most astounding sonic wonders in the United States. The first is a hidden sound installation in Times Square that might be the most visited art exhibit on Earth. The second is an enormous organ built right into the rock of an ancient Virginian cave. These stories originally aired on the Atlas Obscura podcast.

Aural Obscura

If you listen to vintage music, one of the first things you’ll notice is the complete lack of bass. But turn on a Top 40 station today, and you’ll hear song after song with deep, sub-ratting bass tones. So how and why did this change happen? For this episode, we worked with OnePlus to tell the story of our collective obsession with bass, and the one device that transformed the sound of popular music. Featuring hip-hop legend DJ Jazzy Jeff and Roland's Paul McCabe.
