Acoustic Calculator

Purpose: Our Acoustic Calculator helps you determine the reverberation time and/or “echo level” of your room.

Solution: Input your dimensions and material information below. The Acoustic Calculator will provide the Calculated Reverberation Time, and the approximate amount of acoustic treatment needed to meet your Target Reverberation Time.

We have also written extensively on How this Acoustical Calculator works as well as which Room Surfaces affect Absorption Coefficients the most. In Brief, to calculate reverberation values, we use Sabin’s Formula, developed by Professor Sabin of Harvard University to measure acoustical performance. The equation states: RT60=.05*V/Sa, where RT60 is the reverberation time, or more specifically, the time it takes for the reverberation to dissipate below a certain level. 0.05 is a constant derived by Professor Sabin, V is the Volume of the space, and Sa is the Acoustical Absorption of the space, which is simply the Surface Area multiplied by the Acoustical Coefficient of each surface. For more information, check out our blog here.

So you know how much absorption you need to acoustically treat your room. Now What? Check out our Sound Absorption products to select which options fit your budget and aesthetics. Not sure which product is right for you? Use our Product Selector Tool to help choose the acoustical treatment that best fits your needs.

Acoustic Resources

There are a number of Acoustic Case Studies, Acoustic Absorption Articles, and other resources available throughout the Commercial Acoustics site to help answer any questions you may have,

  • Acoustic Case Studies – specific projects that required acoustic panels, ceiling clouds, or baffles to provide acoustic treatment for reverberation issues
  • Acoustic Absorption Articles – Tips and White Papers designed to educate on the specifics of acoustic issues, from calculating reverberation times to focusing on frequency-specific decay times
