Study of Sound Propagation in Air
Abstract
This report summarizes research on sound absorption performed over a three-year period. This research included measurements of the rotational relaxation time in air at elevated temperatures and measurements of the vibrational relaxation of water vapor during collisions with water vapor, oxygen, nitrogen, and argon. As a result of these measurements the range of temperatures over which these basic physical properties can be accurately predicted over the temperature range normally encountered on the surface of the earth. References to the work published in the open literature is given as well as a brief description of how this work contributed to the development of a new procedure to predict sound absorption in still air.
