Abstract :
The investigation of the influence of internal mechanical tensions (IMT) on the signal delay period, the form of impulse response (IR) and amplitude-frequency characteristic (AFC) have shown that IMT change acoustic wave velocity and this change in signal-delay period, is also formed by IR and AFC. In addition, deformational effects is to be taken into consideration.
