Sound Test · At a glance
Quick answer: Play quiet test tones through the left or right stereo channel. A tone confirms audible routing through the selected output path.

How it works and what the result means
A generated sine wave helps check routing and audibility. Speaker, headphone and audio hardware response strongly influence what you hear; the tool cannot measure response without a calibrated recording chain.
Reading the result
A tone confirms audible routing through the selected output path. It does not measure frequency response or speaker distortion.
What to check next
Check mute, output selection and balance if a channel is silent. Stop the tone before changing devices.
Very high or low frequencies may be inaudible on working equipment. Do not increase the volume to chase an inaudible tone. This is not a hearing diagnosis.
Frequently asked questions
Why does the tone play through the wrong device?
The browser normally follows the operating-system audio route. Select the desired output in system or browser audio settings, then restart playback.
How do I start the Sound Test?
Lower your volume first. Select a channel and frequency, then start a quiet tone. Stop playback before changing devices.
Does this tool require a download or an account?
No. Open the interactive tool above in a modern browser. The instructions and explanations are available even with JavaScript disabled; running a test needs JavaScript.
Why can two attempts give different results?
Power settings, background tasks, browser scheduling, operating-system input processing and device settings affect measurements. Compare repeated attempts with identical settings rather than the single highest score.
