The Tone generator: a 440 Hz sine wave in both ears at 20% volume

A test tone is only as useful as the speaker playing it.

The waves.

A sine is pure; a square, triangle and saw add overtones and sound brighter and louder, so the page lowers them.

Useful tones.

440 Hz to tune by, 1 kHz as a reference level, 50 to 100 Hz to test a bass speaker.

Each ear.

Play in the left or the right to check which speaker is which.
