Rules and important details
- A response before the tone is a false start and that round must be retried.
- Keep the same device, audio output and browser when comparing results.
- This is a browser estimate, not a medical hearing or neurological assessment.
Useful termAudio latency is extra delay introduced by the device, operating system, browser and speakers or headphones.
About this audio reaction time test
Measure how quickly you respond to a random sound across five browser-based reaction rounds. The tool runs in your browser, so you can retry immediately without creating an account.
Unlike a visual reaction test, this activity uses a sound cue. Complete several rounds because one result can be affected by anticipation or distraction. The displayed time includes browser and audio-output delay, so use it for repeatable personal comparisons rather than clinical conclusions.
