How to use this test
What to look for
Compare the same listening position and check that mono audio is off if the tone stays centered.
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.
