Classroom Acoustics Information

From the Alexander Graham Bell Association

As they age, buildings can only get noisier, not quieter – cracks form and widen, duct anchors come loose and vibrate, fans and belts begin to squeal. Whatever the mix of exterior and interior noise, the best retrofit solutions are the ones that counteract multiple sources at the same time.

Hiring a qualified acoustician who can help find those solutions is highly recommended, and can leverage all the other investments you make in an existing building.
