How to use this test
What to look for
Repeat at the same volume. The room, speakers, and your hearing all affect which pitches are audible.
Web Audio generates tones for listening checks. Start at low volume and stop if uncomfortable. Audibility depends on the output device and hearing; these tools are not medical hearing tests or calibrated frequency-response measurements.
