Why this is more than a tone slider

It sets levels for your ears

Most people hear high pitches less well, so one fixed volume makes high sounds seem fainter and skews the match. A short level check makes every test sound about equally easy to hear, and finds where your hearing or headphones stop.

It checks the octave

The most common mistake in pitch matching is landing exactly one octave off. After you narrow down, you compare your match with the sounds an octave above and below.

It gives a range, not a fake decimal

You match twice, by two different methods, and get a range that allows for day-to-day variation. Match again on other days and the page averages them, and tells you when they agree. How the method works · Hear single tones

Before you start

Use headphones if you can, wired if you have them. Turn off spatial audio and any equalizer. Sit somewhere quiet. Every sound starts very quiet and you can stop it at any time.

See a doctor if

Your hearing dropped suddenly, the sound is in one ear only, it pulses with your heartbeat, or it comes with dizziness or ear pain. This tool cannot tell you why you hear a sound.
