Acoustics+2

The most important thing in a classroom is that the teacher must be heard by every student in it, without forcing or causing any damage to their vocal cords. There are many ways to achieve this purpose, by using the right materials that absorb low frequency sounds, in large classrooms, part of the ceiling should have materials that helps with the acoustics for the same purpose. Also, the reverberation time must be reduced as much as possible.

You should avoid hard flooring because creates noisy footsteps and scraping noises from chairs and tables which causes distractions. Sound absorption foams are a good option for the walls of a classroom.
