The spike in noise levels makes teaching less effective overall, but by investing in sound panels, teachers will have an easier time communicating with students and controlling the classroom’s attention. Gauge noise levels and learning interferences in the classroom by identifying the amount of background noise (e.g., heating and A/C systems, hallway traffic, outside noises) and reverberation (e.g., high ceilings, large space) that “live” in the classroom, in order to determine needed whole-class accommodations. Click Here for … Analysis revealed that poor S/N ratios were associated with a high background noise level and multifunctional teaching activities. Regardless of whether it’s new construction or renovation, the best solution for both reducing the level of sound in a classroom and limiting sound intrusion into it is an acoustical ceiling panel that combines an NRC of 0.70 or greater and a CAC of 35 or greater.
