Frequency Test
Test your hearing range, check headphones and speakers, or play any tone from 20 Hz to 20 kHz — directly in your browser.
One lab. Three different questions.
Hearing and hardware are not the same test. Start with the thing you actually want to understand.
Hearing frequency test
Estimate the highest frequency you can hear in each ear, with silent control trials and a result reliability score.
Start hearing testHeadphones & speakers
Check bass, treble, left/right routing, balance, buzzing, rattling and frequency gaps with guided modules.
Choose equipment testTone generator
Generate sine, square, triangle or sawtooth tones at an exact frequency, duration and audio channel.

Not hearing 16 kHz does not automatically mean a hearing problem. Every link in the playback chain can change what reaches you.

- Bluetooth processing
- Device sample rate
- System volume
- Background noise
- Browser audio processing
A test that shows its limits.
Browser tools cannot produce a calibrated audiogram. We focus on repeatability, transparent methodology and useful context instead.
Silent control trials
Hearing tests mix silent trials into the sequence to reduce guessing and identify inconsistent responses.
Reliability, not fake precision
Your setup, channel check, silent trials and result consistency contribute to a visible reliability score.
Safe audio defaults
Tones start quietly, fade in and out, stop on tab changes, and never claim a measured sound pressure level.
