SoundTowel Editorial writes the guides and builds the free speaker tools on this site.
Advice about wet phones is easy to find and often wrong: rice, hair dryers and cotton swabs are still recommended on many pages, while Apple’s own instructions warn against all three. Our pages follow the manufacturer’s documentation first and say so, with the date the source was last checked.
The tool plays generated tones in your browser. Where a page describes what the tool does — a 165 Hz tone, a low-frequency sweep, a left and right channel test — that description matches the schedule in the code, not a marketing summary.
