Tones and sweeps, made in the browser.
Steady tones, sweeps and a check of the highest tone you can hear, all made by your browser, with what to watch for in volume.

Every sound here is made as it plays; nothing is a recording.
A steady tone.
Any frequency from 1 Hz to 22 kHz, in sine, square, triangle or saw, in either ear, up to three at once.
A sweep.
A glide from one frequency to another, set on the audio clock so it is exact.
Volume.
Start quiet and turn up slowly: loud high tones can harm hearing and speakers.
