SAE ARP866B – Standard Values of Atmospheric Absorption as a Function of Temperature and Humidity (Stabilized: Dec 2012)

This document has been declared “Stabilized” and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist.

This ARP describes a method by which values can be obtained for the absorption of sound in air over a wide range of temperature and humidity conditions. Although it was developed primarily for use in evaluating aircraft flyover noise measurements, the information should be applicable to other noise problems as well.
