A computer program to calculate the mean absorption or transmission coefficient of a material in any sound field: HPABTRAN (IM-PHYS-049)

Last updated on 23 August 2013 5:43

The transmission and absorption properties of most commonly used acoustic materials are strongly frequency dependent. Hence, the effective absorption and transmission coefficients of a material will depend upon the frequency spectra of the incident sound field. The program calculates the fraction of acoustic energy absorbed by a surface or transmitted...
