Important
- Not a medical hearing test. Missing high tones does not diagnose hearing loss.
Lower system volume first. Sounds never autoplay. Stop immediately if audio is uncomfortable. High tones and sweeps are optional — use briefly.

- No automatic pass/fail or medical conclusion is produced.
Limitations

Troubleshooting

- Check system output device, browser mute, and that you clicked a play button after a user gesture.

FAQ
Is audio uploaded?
No. Tones are generated locally with Web Audio and never sent to a server.
