From classrooms and cafeterias to gymnasiums and hallways, the student educational experience is formed in every part of a school. Accordingly, noise in any of these places can ultimately affect how a student learns, especially with today's new methods of teaching.
Active Learning methods - where lecturing is alternated with problem solving in groups to teach critical thinking skills - have become more prominent than ever, resulting in noisier classrooms. The Americans with Disabilities Act (ADA) is about to require schools to meet standards for reverberation time in classrooms of 0.6 to 0.7 second.
At the same time, school cafeterias, gymnasiums and corridors all have hard surfaces for their purposes and ease of cleaning, none of which absorb sound. Excessive reverberant noise from these spaces is not only an issue within them, as the noise travels easily to affect students and teachers in nearby classrooms and other areas.
Ultimately, controlling noise within school settings can help teachers keep control of their classes, students learn without distraction, and parents feel better that their children are in an environment that encourages learning.
