It’s all about the echo and reverberation. You’re probably familiar with an echo. Whether from the sharp slap of a textbook dropped in an empty hallway or your voice responding back to you as you yell across a vast canyon, we’ve all had a little fun with echo. Well, gym acoustics are a bit like that vast canyon. It’s a large, mostly empty space that’s lined with hard surfaces. As noise travels in this “canyon” we get reverberation that is noticeable in such a large, voluminous space. Add with noisy sports and spectators, you’ve got a recipe for reverberation.
