Ears & Waves

Test your ears. Rest your ears. 🌊

Ears & Waves is two things. First: precise hearing and speaker tests you can run in 60 seconds — how old are your ears, can you still hear 17 kHz, does your subwoofer really reach 20 Hz. Second: long, seamless sounds for sleep and focus — pink noise, brown noise, ocean waves, rain — 10 hours at a time.

Everything is generated mathematically or recorded by us, then calibrated and level-matched. No recycled clips, no loudness tricks. For the tests: use headphones, set a comfortable volume, and never turn it up when the tone "disappears" — that's the point.

New test every week. New 10-hour sound every week. Method and sources in every description.
