WARNING: Starts at full volume! This can be a useful tool for testing your own hearing, also as a masking device which provides the common forms of white and pink noise. However one huge note of caution: do not start this device with headphones in your ears - you risk serious hearing damage! For some strange reason the app designers have encoded this so it automatically opens up with your phone set to full volume, unacceptable. I was able to use it to determine the specific frequency at which my high frequency hearing vanishes (8.4 kz)

Works, but two complains 1: Upon starting, my phone asks if I am sure I want to crank the earphone volume up to 100%, indicating that some app tried to do so. 2: It stops when the screen goes to sleep (after 30 seconds in my phone) making it useless for ambient sound continuous blocking.
