Enable sound, wait through a randomized silent interval, and click as soon as you hear the tone. The screen deliberately stays visually neutral.
The timer starts when the browser schedules the audible tone and stops on your next pointer press. Five valid cues produce an average and best response.
Bluetooth transmission, operating-system audio buffers, wireless power saving, and speaker processing can add delay. Use wired headphones in a quiet room for the most repeatable setup.
Do not compare a Bluetooth run directly with a wired run.
The displayed bands match the visual reaction tool for a simple reference, but auditory and visual pathways are different. Compare sound tests with prior sound tests.
These browser tests are for self-comparison and gaming practice. They are not a medical, psychological, or professional diagnosis.
The visual state stays neutral so the measurement is driven by the audio cue rather than a simultaneous color change.
Yes. Bluetooth audio can add substantial and variable latency. Wired headphones or device speakers usually provide a more stable browser result.
Modern browsers require a user gesture before a page can start audio. Your first ready click unlocks the audio context and begins the randomized wait.
