Audio Reaction Test shifts the reaction cue from visual change toward hearing. A short tone plays after a random delay, and your goal is to respond when the sound arrives without guessing early. The screen still gives feedback for accessibility, but the useful comparison is how your hand answers a sound cue versus a color cue. This helps you notice whether waiting by ear feels steadier, slower, or more tempting to anticipate than waiting by sight.
Turn the volume to a comfortable level, wait for the tone, then click, tap, press Space, or press Enter. Acting before the tone counts as a miss. Use the same hand position each round so the measured difference is mostly listening and response, not travel distance. If audio is muted by the browser until the first gesture, click once to allow sound and then restart the run.
Fast correct responses add more points, while premature clicks lower the control percentage. The auxiliary score is not a hearing test; it simply shows how cleanly you waited for the cue across rounds. A good run has similar timing from round to round. Very fast times paired with many false starts are weaker than a slightly slower run where every response follows the tone.
Listen broadly instead of staring harder at the center. Many players tense up and start reacting to expectation rather than sound. Let the delay be random, keep breathing normal, and move only when the tone is clear. If you miss after a long wait, practice staying ready without counting seconds. For comparison, play a short visual reaction set and then this audio set using the same device position.
On mobile, check that the browser allows audio and that the speaker is not covered by your hand. Use headphones only if latency feels consistent; wireless devices can add delay that changes the result. Keep the phone on a surface or in a stable grip. Tap near the center after the sound, and avoid double tapping because the second tap can become an early action for the next round.

Listen for the tone, then click or press Space as soon as it arrives.
