Application of Pure-Tone Atmospheric Absorption Losses to One-Third Octave-Band Data
This document presents a practical method for calculating atmospheric absorption for wide-band sounds analyzed with one-third octave-band filters, called the SAE Method. The SAE Method utilizes pure-tone attenuation algorithms originally published in ISO 9613-1 and ANSI S1.26-1995 to calculate path-length attenuation at mid-band frequencies. The equations introduced in this standard transform the pure-tone, mid-band attenuation to one-third octave-band attenuation.
Rationale: Atmospheric absorption is an important component of acoustic propagation between a source and receiver. This ARP overviews an updated methodology to calculate atmospheric absorption consistent with current scientific information.
