How this sound test works
We generate precise audio signals in your browser. You listen and confirm the result, so the diagnostic workbench reflects the real speakers, headphones and room in front of you.
Sound Test
Fast, reliable and private audio testing — right in your browser. Test first, then turn what you hear into practical fixes.

Start diagnosis →Browser limits
Web Audio can control the digital test signal, not inspect a physical driver or calibrated sound pressure. Device labels, sample rate conversion and output selection vary by browser.
Start with the problem you can hear
A good diagnosis begins with an observation, not a claim that the browser already knows what failed.
01No soundNothing plays from speakers or headphones.02One side is silentLeft or right audio is missing.03Audio is unbalancedThe stereo center pulls to one side.04Crackling or distortionAudio buzzes, breaks up or rattles.05Sound is too quietOutput is present but unusually low.06Bluetooth is delayedWireless audio is late or unstable.
A result you can explain
The test records only the answers you choose. Diagnosis rules then rank likely causes and show the evidence behind each one.
Read the methodology →What the browser can verify
- The frequency, waveform, channel and level of the generated digital signal.
- Whether Web Audio and microphone APIs are available.
- The sample rate reported by the active browser audio context.
What only you can verify
- Which physical side played and whether it sounded balanced.
- Whether the signal was clear, delayed, distorted or missing.
- Whether a proposed repair changed the real result.
Test with a procedure, not a guess
App-specific and system-level checks that begin with the same controlled browser signal.

Sound test questions
How does an online sound test work?
The browser generates a known digital signal and sends it to the output selected by your operating system. You confirm what you physically hear, because the page cannot listen to speakers automatically.
Is this sound test private?
Yes. Output signals are generated locally. Microphone tools ask permission and process samples in the browser; recordings are not uploaded or saved to history.
Can the site identify my exact speakers or headphones?
Usually not. Browsers intentionally limit output-device details. Where a native output picker is supported we expose it, but we do not invent a device name.
Why can I see movement but hear no sound?
The wrong system output, a muted volume stage, disconnected hardware or autoplay policy may be involved. Start the guided no-sound diagnosis.
Is this a hearing test?
No. It checks an audio signal path and relies on subjective confirmation. It is not a medical or calibrated hearing assessment.
