Abstract
The author has recently presented a waveform inversion technique for measuring elastic wave attenuation in cylindrical bars. However, it is worthwhile pointing out some previous, relevant studies which may have been overlooked. The Pochhammer technique employed to derive the pulse attenuation characteristics is not new. In fact it was first used by Hsieh and Kolsky (1958); Blair (1985, 1990) also implemented the method using a Fast Fourier Transform.
