Dog Whistle is a fun application from hermanm over @ xda-developers. When you launch the app , you can use the slider to select the required frequency and then press on the whistle to blow the whistle. Depending on how old you are, you may not hear anything. Good way to test it is go find some dogs and try the app and watch em go nuts. Wouldn’t recommend leaving the sound on for too long.

If you find this tool useful, please donate to the developer.
