This Frequency Sound Generator app lets you generate a simple form sound generator with a frequency between 1Hz and 22000Hz.
It is simple, accurate and very easy to use. Adjust tone frequency using a slider or number pad and press the play button.

This sound generating app can be used in multiple use cases:
1. You can test your hearing. Human being is capable of hearing frequencies in
average range of 20Hz-20000Hz. This range is getting smaller by the age.
2. Cleaning water from your smartphone speaker. Since sound is making small
vibrations it can help shaking of unwanted water from your speakers.
3. Testing your speakers for the high end (treble) and low end (bass) tones.
4. Having fun and making experiments with sounds.
