Your hearing.
Your way.
OtoCorrect helps you find the right distance for a conversation, shape sound to fit your own ears, and check how you're hearing across the frequency range — all running privately in this browser tab.
Distance
Uses your camera to estimate how far you're sitting from the screen, and flags whether you're in a comfortable range for face-to-face hearing and lip visibility.
Sound
A simple on-page equalizer so you can shape a test sound to what's clearest for you — boost speech frequencies, ease off the highs, or build your own curve.
Hearing Test
A one-minute, self-guided check across six frequencies. Click as soon as you hear each tone, and see the results laid out as a simple audiogram.
Find your hearing sweet spot
Center your face in the frame. OtoCorrect estimates how far you are from the camera and flags whether you're sitting in a generally recommended range for clear face-to-face hearing and lip visibility — useful for conversations, video calls, or hearing device fitting checks. Nothing is recorded or uploaded; video is processed locally in this tab.
This can't touch your computer's system volume or any other app or tab — only sound played here.
It can only change volume on the device that's currently playing — it can't start, stop, skip, or change what's playing, and it can't touch your system volume.
Shape sound to your ears
Play a built-in test sound and reshape it with six frequency bands, from low bass up through treble. Try a preset for a common comfort curve, or drag each slider to build your own.
Built-in audiogram
A short, self-guided check across six frequencies (250 Hz–8 kHz), about ten seconds each. Put on headphones in a quiet room, set a comfortable volume, and click the button the moment you hear each tone.
Each tone starts silent and gradually gets louder. Click "I hear it" as soon as you notice it — the sooner you click, the more sensitive your result at that frequency. If you don't hear it before time runs out, the test just moves on to the next tone.
