Listen for the beep, then click as fast as you can. A free, browser-based audio reaction time test with rounds, averages, and a best-score tracker.
This test measures auditory reaction time — how quickly you respond to a sound cue. It's a distinct skill from visual reaction time, since your brain processes sound through a different pathway, and most people react to audio cues slightly faster than to visual ones.
Click anywhere to arm a round. After a random delay of 1.2–4 seconds, you'll hear a short beep — click (or press Space) as fast as you can when you hear it. The delay is randomized on purpose so you can't predict it; clicking before the beep counts as a false start and restarts the round. Your time is recorded across a set number of rounds, and the average of your best run is saved on this device.
Turn your volume on before starting. Press Start exercise, set the number of rounds (3–10) in the controls panel, then click to arm each round and wait quietly for the beep.
Don't try to anticipate the exact timing — the randomized delay is what makes this a genuine reaction test rather than a rhythm-guessing game. Typical adult auditory reaction times fall in the 150–300ms range; a few false starts are normal while you calibrate to the format.
Timing is measured with standard browser JavaScript timers, so results are a useful relative benchmark rather than a lab-grade measurement, and this isn't a medical or diagnostic test — see the Disclaimer for details.
