AHRI 885 Specification Calculator

Calculations Based on Desired Room Sound Pressure

AHRI 885 Specification Calculator

This spreadsheet is based on the "AHR 885 Calculator" spreadsheet, but runs the calculations in reverse order. Just input the desired room sound spectra (examples are provided on the discharge sheet). The program then determines the maximum sound power that will result in the desired room sound pressure.

The spreadsheet has two main tabs, for discharge and radiated sound power specification values.

Additional Information

Additional tabs include the calculations per AHRI 885, an NC table, and the dBA calculator. The executable program, "Soundspec Tool", does similar calculations and outputs a text file in guide specification format.
