Noise Control "ask" people to shut up by "saying SHHH..." automatically! Yes, this is the Noise Control App used by many elementary teachers for innovative classroom noise management!
Noise Control is the pioneering intelligent iPhone App of its kind and we are proud of your precious support for innovation!
What's more, Noise Control is interculturally effective since "Shhhhh.... " is quite simply a cross-cultural way of saying Shut Up!
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.
