METHOD & EVIDENCE
Speaker Cleaner test method and evidence
This page records what can be reproduced from public documentation, what is chosen by the product implementation, and what is still unmeasured. It does not turn a manufacturer support case into a SpeakerCleaner result.
Published method record
The table below is the complete status of the method record. “Not published” is intentional: it prevents a public source or a product setting from being presented as a device experiment.
| Field | Current record |
|---|---|
| Test device model | No device-specific result is published here. A future record must name the exact model and speaker output path. |
| Operating system and browser | No device-specific result is published here. A future record must name the OS version, browser, and browser version. |
| Test date | No product test date is claimed. This page was reviewed on 2026-10-08; that review date is not an experiment date. |
| Volume setting | No calibrated SPL measurement is published. Use a comfortable device volume and stop if playback is painful or harsh. |
| Frequency range | The current cleaning implementation uses a 150–190 Hz sweep. This is a product implementation choice, not a manufacturer recommendation. |
| Duration | The current cleaning implementation runs for 90 seconds. This is a product implementation choice, not a manufacturer recommendation. |
| Before/after listening or recording | No before/after listening log or recording is published because there is no reproducible device record to identify. |
| Failure cases | No success rate or failure rate is claimed. Public manufacturer cases describe symptoms and care steps; they do not test SpeakerCleaner. |
| Results that cannot be repeated | Not measured or published. A future report must state the setup and the exact condition that failed to repeat. |
Evidence levels for the cleaning cycle
- 150–190 Hz: a documented parameter in the current product code. No cited manufacturer source establishes it as a universal cleaning frequency.
- 90 seconds: a documented product duration. It is not a manufacturer safety limit or a measured success threshold.
- Sweep mechanism: browser audio can generate and route tones through the Web Audio API. Whether that movement clears a particular device is unverified without a named, repeatable device record.
Public reference cases
These are real manufacturer support cases used to set safe boundaries. They are not controlled experiments and do not measure SpeakerCleaner efficacy.
- Apple speaker symptoms: Apple describes checking the opening, removing a case or film, and using a small, soft, dry brush when sound is muffled or distorted. See the Apple speaker troubleshooting guidance.
- Apple after liquid: Apple advises placing an affected iPhone speaker-side down on a lint-free cloth after liquid exposure and explains the limits of water resistance. See the Apple splash, water, and dust guidance.
- Samsung speaker distortion: Samsung documents that water can affect speaker sound and provides drying and troubleshooting steps. See the Samsung speaker troubleshooting guidance.
How to add a future device result
Record the exact device model, OS, browser and version, date, volume setting, frequency range, duration, speaker output path, and before/after listening or recording result. Repeat the same setup at least once, report failures and non-repeatable outcomes, and distinguish a measured observation from an implementation choice.
Until that record exists, use the Speaker Testas a listening aid and follow the device maker's instructions for liquid, dust, distortion, or suspected device problems.
