This simple hearing test app allows you to generate a tone of any frequency human ear is able to percieve. The generator produces frequencies from 20Hz to 20kHz. You can check your hearing for this frequency range if your speaker supports it.
Most adults cannot hear frequencies beyond 17kHz, while children and teenagers typically can. Check how old your ear is.
The app generates a clean sine wave for the entire frequency range. You may hear crackling, depending on your sound device capabilities. Keep in mind that most mobile phone speakers cannot reproduce the entire range.
The app supports light and dark themes and the fluent design system with acrylic window color.
