ASA S3.4 – American National Standard Procedure for the Computation of Loudness of Steady Sounds
This standard specifies a procedure for calculating the loudness of steady sounds as perceived by listeners with normal hearing. The procedure is based on the spectra of the sound. The possible sounds include simple and complex tones (both harmonic and inharmonic) and bands of noise.
The standard is applicable to sounds presented in free field with frontal incidence, in a diffuse field, or via headphones.
A computer program, which performs the computation and provides estimate in sones, and the corresponding loundes level in phons, is provided. Use of this software is not required for conformance.
The downloadable version of this item is a “.zip” file which contains a PDF version of the standard as well as the software program files.
