Why is my gymnasium so loud?


Gymnasiums are typically large over-sized shoe box shaped rooms filled with hard reflective surfaces suitable for sporting events and gym class.   Soundproofing a gym is all about controlling the ambienet level of echo that reflects around the space.  In an untreated gym, those echoes can carry for up to 10 seconds before they die off on their own.   But human ear can only tolerate 2 seconds or less worth of echo before it begins to sound like noise.

As sounds are generated within the gym, the sound waves carry at excessive speeds (768 mph) and reflect time and again off the perimeter walls, floor and ceiling.   As these echoes continue to carry, they create what is called "background noise".    What your human ear is hearing in the gym is a combination of original sound and reflected sound.   Concrete, wood, metal, glass, brick, and drywall are the typical surfaces found in a gym.   These surfaces combine to absorb on average 5 percent of the echo.  

Sound panels can absorb up to 80% the reflected sound waves   To control the level of noise in your gym, add enough sound panels to capture the echoes that are causing your problem.   The key to the success of your gym soundproofoing treatment lies in calculating the right amount of material based on your gym's size, shape and surface textures.   Sound baffles called VET Baffles are the most popular treatment for improving the acoustics within your gym space.
