Auditory Reaction Time Test
Wait for a random 1.5–4 s delay, then react to an 880 Hz beep. Space works too. Wired headphones minimize Bluetooth codec latency.

How to use
- Click the stage (or press Space when prompted) to arm each round.
- Wait for the beep after a random 1.5–4 second delay—do not click early.
- Click or press Space immediately when you hear the tone.
- Complete five rounds, then use Reset for a fresh session.
FAQ
Why are my times higher on Bluetooth?
SBC/AAC codecs add 40–200 ms of latency between the browser and your ears. Use wired headphones for fair comparisons.
What is a typical adult score?
Roughly 180–280 ms after subtracting audio latency. Auditory reaction is usually faster than visual because sound reaches the brainstem in fewer processing steps.
Overview
This test plays a short 880 Hz oscillator tone after a random delay and measures the gap until you click or press Space. False starts (clicking before the beep) are flagged so you can re-run the round honestly.
