HOW TO CREATE GREAT AUDITORIUM ACOUSTICS
Acoustically treating an auditorium can be a tricky thing to do.
The answer is to use a combination of absorption and diffusion.
The absorption reduces the amount of noise in the room so there is less reverberation.
Diffusion breaks up and disperses the sound waves that aren’t absorbed.
This reduces slap-back echo (reverberation between two parallel walls) and allows
for the leftover sound to reverberate without being disruptive.
