Measurement of the absorption spectrum using correlation/spectral density techniques
The correlation peak-height ratio method for the determination of acoustic absorption coefficients is reviewed. In addition, a method utilizing a truncated cross-correlation function and spectral density ratios is presented; it enables the calculation of an absorbing material's absorption spect...
