ACOUSTIC ABSORPTION COEFFICIENTS OF HUMAN BODY SURFACES
Abstract
Reverberation chamber decay times were measured with and without human body surfaces exposed to the sound field. From these measurements, acoustic absorption coefficients were computed for human body surfaces. These were small compared to similar coefficients for laboratory animals. Typical values for the absorption coefficients measured for human body surfaces were in the range of 1 to 2 percent. Little variation was found from 1 to 20 kc. Measurements wd with other values obtained by different methods.
