Self conscious elementary school children with hearing disabilities often compromise their quality of classroom education due to their inability to fully decipher what their teacher is saying from the background noise generated by their peers.

Sound Engineering has developed the Class Room Noise Buster (CRNB) to solve this problem.

The CRNB, a small portable device equipped with super bright lights, placed at the front of the class, signals to the noisy students by means of turning on a yellow light when there noise is beginning to interfere with the impaired child’s ability to hear the teacher and a red light when noise is at an unacceptable level for the child hear the teacher. The child easily adjusts the threshold for each light by means of a wireless keychain.
