Noise & Sound Control for Educational Facilities

Educational facilities are most commonly built with hard surfaces, such as brick and block, which are very poor for room acoustics. Acoustics are important in instructional spaces. Classrooms with excessive reverberation from noise make it difficult for students to hear and understand what is being taught. Some children with learning disabilities can struggle even more when there is excessive noise and reverb causing low speech intangibility.

The American Speech­ & Hearing­ Association issued the document “Position Statement and Guidelines for Acoustics in Educational Settings”. This document outlines and sets standards or guidelines for the room acoustics of ambient noise levels or back ground noise and a suggested a Reverberation Time of .5 seconds or (RT 60) of in the speech intelligibility range in classrooms.


This will absorb the projected sound when it hits the rear wall eliminating echo and reverb greatly.

AC100 will also help the acoustics of the space. Walls sometimes develop flutter echo in some spaces. This can be treated with SonicSorb Wall Panels as needed to hear the instructor clearly and gives them the ability to focus on the instructor instead of unwanted echo and reverb that often is very distracting in a classroom environment.

Acoustic materials should be installed on the rear of the classroom opposite the instructor. Adding some treatment to the ceiling like a high rated NRC tile such as our SonicSorb Side walls can additionally be treated as needed to achieve even better acoustics.

These guidelines will greatly increase the acoustics of classrooms allowing each student to
