Twenty Thousand Hertz

He was deaf for 35 years + Listener Stories kickoff

Last year, we ran three full episodes of listener-produced stories. But one beautiful story was just a little too long for the final cut… and we couldn’t leave it behind. In this episode, sound designer Jesse Herrera [https://www.herrerasound.com/] tells the story of his grandfather, who lived in silence for 35 years before receiving a cochlear implant, and the overwhelming, joyful process of learning to hear again. Afterwards, Dallas and Casey reflect on last year’s Listener Stories and kick off this year’s competition.  Learn about this year’s Listener Stories competition and submit your story at 20k.org/2026 [https://20k.org/2026].

Harry Potter and the Sound Designer’s Stone

Harry Potter has been brought to life on page and screen. But what would it take to make the wizarding world come alive using sound alone? In this episode, we go behind the scenes of the new full-cast editions of the Harry Potter series, where a team of sound designers spent eighteen months crafting 130 hours of immersive audio. From the whistle of the Hogwarts Express to the rasp of the Dementors, every spell, creature, and location had to sound tangible and emotionally distinct.

When Everything Stopped, He Started Listening

David Jeffers [https://quadriphonicsound.com/] has always understood the world through sound. As a kid, he bounced beats between tape decks and built speaker boxes from spare parts. After college, he founded an underground hip hop label. Then came the day that split his life in two. And in the quiet that followed, David started listening more deeply… and piece by piece, he built a new life, guided not by what he lost, but what he could create.

Doctor Who & The BBC Radiophonic Workshop

What does a time machine sound like? Or a magic carpet? For the BBC Radiophonic Workshop, that was just another day at the office. For 40 years, this oddball collective of engineers and composers pushed the boundaries of sound design, crafting eerie atmospheres, quirky jingles, and the iconic audio of Doctor Who. In this episode, we explore the rise and fall of this pioneering studio with composer and archivist Mark Ayres [https://www.instagram.com/markayresrws], and uncover how these sonic wizards shaped the future of sound.
