How to Calculate Reverberation

Reverberation is produced when sounds echo in an enclosed room or space. The sounds build and are soaked into the walls of the room. Reverberation time is essentially the length of time the sound takes to decay. This measurement may be calculated with an algorithm, but it is difficult to measure without a computer.

Things You'll Need

• Computer Building information

Instructions

1. Go to www.armstrong.com/reverb/step.jsp.

2. Select the type of building space and dimensions for which you wish to calculate the reverberation. Click "Next."

3. Enter the location of your project or building. Include city, state and ZIP code. Click "Next."

4. Submit the specifications of each wall in the building. Include wall dimensions, materials used, and percentage of the room the wall takes up.

5. Click "Calculate." Look at the reverberation time graph: The graph of the time reverberation is in red, the recommended time reverberation is in green.

Tips & Warnings
