A Noise Level Meter built to help control the noise level of groups of children. As the noise level in a classroom increases beyond an acceptable level the noise level meter dynamically indicates the level of noise, and the background graphics within the app change to reflect the noise levels.

The TooLoud! app is ideal for the teacher who needs to limit noise in the classroom environment. It records decibels, displaying the volume levels in numbers. Use it to let the class know when they cross the auditory line. Hook your iPad up to the projector and manage the working noise level in class by letting the students see the feedback for themselves.
