How to use it
- Lower the system volume. Select the intended output here if supported, otherwise in system settings.
- Play Left, then Right, then Both.
- Confirm each channel only if you actually heard the expected output.
- Stop sound or reset; review a local report if useful.
If Left is audible in both earpieces, inspect mono-audio and channel-mixing settings. Generating a signal alone does not confirm working speakers.
Details & limits
Explicit playback only, 440 Hz / 1.6 seconds with volume ramp. Browser/system output routing; no microphone capture or sound-pressure measurement.
Does this measure hearing or speaker quality?
No. It records voluntary listening observations. Digital gain is not a calibrated acoustic volume and this is not a hearing test.
