A better hearing loss simulator

Not quieter.Different.

Hearing loss doesn’t just turn the world down. It takes away particular pitches, blurs the rest together, and sometimes adds a ringing that never stops. Hear it for yourself, or let someone else hear it the way you do.

Mild Sensorineural

Watch the consonants go

S, F, TH, and SH are high-pitched and quiet, so they’re the first sounds to go in the most common shape of hearing loss, whether it’s there from birth, comes from noise, or arrives with age. The vowels hang on; the words get harder to tell apart.

What you can do here

Real audiograms

Fifteen profiles from common clinical patterns.

Live signal processing

One filter per ear, shaped to follow the audiogram’s line across every pitch.

A cochlea you can spin

Hair cells mapped to pitch, lit by the sound that gets through.

Hearing self-test

No audiogram? Map out an estimate with your own headphones, then hear it in the simulator, keep it, or bring it to your doctor.

Take the test

Tinnitus

A tone that won’t go away, at whatever pitch and loudness you choose.

Share anything
