Test de Son et Haut-Parleurs

Click the 'Test Left Speaker' and 'Test Right Speaker' buttons in our Audio Diagnostic Suite. You should hear a clear 1kHz sine wave sound coming exclusively from the left ear/channel, then exclusively from the right ear/channel. If sound comes from both or the wrong side, your audio channels are reversed or set to mono playback.

If your smartphone speaker sounds muffled after being exposed to liquid, launch our Water Eject Sound tool under specialized tools. It emits a 165Hz low-frequency kinetic pressure wave that creates physical air vibrations to dislodge water droplets from phone speaker grills.

Human hearing ranges from roughly 20Hz (deep sub-bass) to 20,000Hz (high treble). Running a logarithmic 20Hz–20kHz frequency sweep tests if your speakers or headphones can accurately reproduce all audible frequencies without cabinet rattle, distortion, or dead frequency ranges.

Use our Microphone Verification Engine or Decibel Meter tool. Speak into your microphone to record ambient room noise level in quiet conditions, then test active speech levels. High background noise indicates a low signal-to-noise ratio (SNR) or gain staging issues.

Speaker crackling is usually caused by physical voice coil damage (blown speaker cone), dust build-up, loose audio cables, or digital audio buffer underruns. Use our Speaker Crackling Test to pinpoint mechanical distortion vs software buffer issues.

Yes! Our Surround Sound Test routes distinct channel audio signals across multi-channel audio interfaces to test spatial positioning in 5.1 and 7.1 speaker systems.
