Wavelet analysis on acoustic signal propagation characteristics

Select 7 kinds of different diameter waveguide rod, carried out the breaking-lead experiment on the center of section and the circumference of length with 3.2m, 2.5m, 2.0m, 1.5m, 1.0 m. Then concluded the change of P-wave separation and amplitude by the diameter and the length. Advanced the principle for choosing in practice. By analysing the signal time-domain, calculated the speed of the acoustic signal transmitting in the waveguide rod. Put forward that the speed changes, can effect the location.
