Acoustics Calculator

Room Acoustics is the study of the effects of sound in a room in relation to the overall desired sound quality of that room. Taking into account any existing acoustical properties of the room, one can take some simple room measurements to calculate the amount of sound absorption that can be added to the room to achieve the desired acoustical environment. Please refer to our room acoustics calculator document for more information on how to determine your specific reverberation goals.

MBI's Sound Fact Tip

Hard, reflective, nonporous interior building surfaces such as glass, wood, plaster, brick and concrete absorb 2% to 5% of the sounds striking the surface and reflect 95% or more of the sound. Absorption coefficients are expressed as a percentage of sound absorbed. A perfect sound absorber is an open window since it permits 100% of the sound to escape and not return.
