This audiometer measures your hearing sensitivity by sweeping through frequencies until you can detect them.
You will be tested across three volumes and two frequency ranges for the left ear, right ear, and both ears.
The session produces an audiogram showing the range of sounds you can hear.
Hold the spacebar to sweep through frequencies.
Release the spacebar the moment you hear a tone.
Press Enter (or tap Confirm → on touch screens) to move on.
There are 24 trials: 18 frequency sweeps followed by 6 volume sweeps.
