The White Noise Boom

White noise has a very precise technical definition, but people use the term loosely, to describe all sorts of washes of sound—synthetic hums, or natural sounds like a rainstorm or crashing waves—that can be used to mask other sounds. Twenty years ago, if you’d told someone white noise was a regular part of your life, they would have found that unusual. Nowadays, it’s likely they use it themselves or know someone who does. The global white noise business is valued at $1.3 billion; TikTok is full of people trumpeting its powers; and Spotify users alone listen to three million hours of it daily. Far more of these sounds already exist than any one person could need—or use. And yet, more keep coming.  Looking out at this uncanny ocean of seemingly indistinguishable noises, we wanted to see if it was possible to put a human face on it; to understand why there is so much of it, and what motivates the people trying to soothe our desperate ears with sounds you're not really supposed to hear. In this episode, you’ll hear from Elan Ullendorff, who writes the illuminating Substack Escape the Algorithm; Stéphane Pigeon, founder of myNoise; Brandon Reed, who runs Dwellspring; and Mack Hagood, author of Hush: Media and Sonic Self-Control and host of the podcast Phantom Power. We’d also like to thank Dan Berlau, Sarah Anderson, and Ashley Carman.  This episode was written by Katie Shepherd, Evan Chung, and Willa Paskin. It was produced by Katie Shepherd. We produce Decoder Ring with Max Freedman, and Evan is also our supervising producer. Merritt Jacob is Senior Technical Director.
