I think folks are missing the point in their answers. A 100 person choir does, in fact, produce 100 times the vibrations as a 1 person choir. However, the human brain perceives this energy on a logarithmic scale. That allows us to hear a quiet whisper and a loud gun shot, which are many orders of magnitude different in the amount of air vibration.
