Abstract
A device developed to measure small changes in sound velocity is being redesigned to measure sound velocities in solids and liquids. A 10‐megacycle pulse of approximately 2‐microsecond width from a pulse generator is sent through the sample, amplified, rectified, and sent back into the pulse generator thus triggering the next pulse. The combined acoustical and electrical delay time is determined by counting the number of pulses which traverse the sample in an accurately determined time interval. The electrical delay time is eliminated by using another specimen of slightly different length. From the acoustical delay time and the measured dimensions of the sample, the sound velocity is then calculated.
