Noise Control is the pioneering intelligent iPhone App of its kind and we are proud of your precious support for innovation!

Tired of constantly asking your kids to stop making noise? In a library and want those talking people to stay quiet but don't want them to know you are the one who "SHHH...." them? "Noise Control" handle these for you automatically!


"Noise Control" continuously monitors the ambient sound level. If the sound level is higher than a user specified "Noise Limit" for enough time (e.g. 1.5 seconds), "Noise Control" will "SHHH..." automatically.
