Full Description

This Standard specifies an analytical method to calculate the attenuation of sound as a result ofatmospheric absorption for a variety of meteorological conditions when the sound from any moderateamplitudesource propagates through the atmosphere. The calculation method of the Standard applies formolar concentrations of water vapor in the atmosphere from less than 0.005 percent to greater than 5percent and for ratios of the frequency of the sound to the atmospheric pressure from as low as4 ? 10-4 Hz/Pa (40 Hz per atmosphere) to as great as 10 Hz/Pa (1 MHz per atmosphere).
