Room Sound Calculator

Compute NC, RC, and dBA Values

The Room Sound Calculator is designed to allow computation of NC, RC and dBA values from known room sound pressure levels. A number of apps are available for both iPod and Droid smart phones that can measure the room sound power, by octave band.

Just input the reported room sound spectra and the program calculates the single number values. (dBA is included, as it is the requirement specified by the new classroom sound level requirements recommended by the ADA, and required by LEED for Schools.) The program then plots the room sound pressure values.
