## Librarian Description
Wish you could automatically tell the people around you to be quiet while you&#039;re trying to concentrate on an important task?

Want to wake up at the slightest noise around you in an unfamiliar environment?

Librarian for the iPhone does all of this (and more coming soon)! 

Simply set the audio level sensitivity and tap start to begin.  Once the noise surrounding you exceeds the set sensitivity level, those around you will be politely notified with a &quot;shhhh&quot;.
