Audio Reaction Time Test
How fast do you react to sound? After a random pause you'll hear a short beep. Nothing changes on screen, so you can only react to what you hear. Click, tap or press Space the moment the beep plays.

About this test
Auditory reaction time is how quickly you respond to a sound. Studies comparing simple auditory and visual reaction times generally find responses to sound are somewhat faster, partly because auditory signals reach the brain's processing areas more quickly.
The beep is generated in advance with the Web Audio API so there is no loading delay, and timing starts when playback is triggered. Your audio hardware still adds output latency. Wired headphones or built-in speakers are typically faster than Bluetooth, which can add a noticeable delay.
If you hear nothing
- Check the tab isn't muted and your phone isn't on silent.
- Browsers only allow sound after you interact with the page. Click the test area to unlock it.
- If audio still can't play, the test shows a fallback message instead of measuring silently.
Results are measured in your browser and include some device latency. Read the methodology and disclaimer.
