How to Use the Audio Reaction Time Test
Most people react faster to sound than to light. This test plays a beep after a random wait and measures how long you take to click. Compare it with the visual reaction time test. We subtract the audio output delay your browser reports, so Bluetooth headphones are less of a problem.
- Click the box. The test starts and goes quiet.
- Wait for the beep. It comes after 1.5–4.5 seconds.
- Click fast. Click or press Space when you hear it.
- Repeat. Do 5–10 tries and look at your average.
Average Audio Reaction Times
| Time | Rating |
|---|---|
| Under 150 ms | Excellent |
| 150–200 ms | Good |
| 200–250 ms | Average |
| Over 250 ms | Slow, or high audio delay |
Why Is Sound Faster Than Sight?
The ear turns sound into nerve signals faster than the eye processes light, so reactions to sound are usually quicker. That is why sprint races start with a sound, not a light.
Reduce Delay
- Use wired headphones. Bluetooth can add 100–200 ms.
- Close other tabs that play sound.
- Use a mouse with a low click latency.
