| Field experiment results are presented on the measurements of the acoustic wave velocity and attenuation in
snow. The experimental technique is discussed. Signal oscillograms and corresponding spectra of a periodic acoustic
pulse series generated by a loudspeaker and recorded by a microphone and a seismic detector are demonstrated. The
results can be applied in the design of active pulse-echo sonars and passive acoustic sounding devices to search for
people buried in the snow. |
