What happens when you press Play?

The browser generates a sine wave and sends it to your device’s selected audio output. Playback starts after your action, fades in and out, and ends on the audio clock. Stop or Escape ends a session early. Leaving the page or hiding the tab also stops playback.

The sound sweep moves upward and then downward through a limited range; the speaker test rises through a different range and offers channel selection. Neither is a verified dust-removal treatment.

What does the progress bar measure?

It shows elapsed playback time. It does not measure sound reaching your ears, water removed, dirt loosened, or damage repaired. The tool never listens to your speaker.

Can the water tone help?

Movement at a speaker opening may help shift loose droplets nearby. We have not established a universally effective frequency, a repair success rate, or removal of internal liquid. Follow the manufacturer-based drying guidance; a tone cannot establish that charging is safe.

What does the stereo test prove?

It helps you listen to the selected left or right channel. A mono setting or device can combine channels. The sweep is not a full audible-range test, a calibrated loudness measurement, or a hearing assessment. See the speaker test for interpretation.

Compatibility and privacy

The tool requires a Web Audio-compatible browser and working output. We have not verified every real device or browser. Audio generation happens locally, without microphone access, recording, or audio uploads. See the privacy notice for hosting and planned services.
