Start with your device volume lowPure tones can feel louder than music. Raise the volume only if needed.
SELECTED SIGNAL
Voice1,000 Hz · 0.7 second pulseADVANCED SIGNALS
Find problems a single tone can miss.
One side sounds weaker?
Use the same tone and level on left, then right. Check balance settings and cable connections before assuming hardware damage.
A frequency disappears?
Small speakers naturally miss deep bass, while high-frequency hearing varies. Sudden gaps in the sweep are more useful than absolute loudness.

Cosa conferma questo risultatoThe listener could hear the generated channels and frequency checks and recorded whether repeatable audible problems were present.
Cosa non può dimostrareAcoustic frequency response, safe sound-pressure level, amplifier power, or whether a problem originates in the speaker, enclosure, operating-system processing or hearing.
Signals are generated locally with the Web Audio API. KeyTest does not listen through your microphone or automatically judge the speaker—the final result comes from what you hear.
