MEASUREMENT OF TIME DISTRIBUTION OF LONGITUDINAL AND CROSS ACOUSTIC WAVES IN SOLID BODIES
The impulse and phase methods have been used to determine the speed of longitudinal and cross waves in amorphous solid bodies on the basis of a modern digital two-channel oscillograph and a generator of signals. In a phase method the technique of definition the time distribution of acoustic fluctuations has been proposed on the basis of sinusoidal signals representation from a source and a sound receiver in a frequency view with the help of Fourier’s discrete transformation. Control measurements have been carried out.
