Results of experimental investigation of acoustic compressional pulses in copper are presented. The pulses in wires were generated by impact of a steel sphere on an end face of a wire. As a result, the pulses with pressure amplitude up to 60 MPa were generated. The dependences of the velocity and spectrum transformation of the pulse on its amplitude are investigated.
