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.


There is no substitute for an Acoustical Consultant, this calculator is a elementary tool to help determine your basic needs. Please contact us for help in finding your local Acoustical Consultant.

MBI's Sound Fact Tip

A distinct repetition of a direct sound is an echo. In a highly reverberant room, an echo gets lost in the general reverberation. An echo is easily distinguished if the interval is greater than ½ second in a room with low reverberation time. Sounds reflected from flat surfaces will be less intense than the original direct sound. Sound reflected from concave surfaces has a focusing action that produces very annoying echoes.
