Abstract
An automatic distance amplitude correction device for automatically correcting for amplitude variations and signals caused by the attenuation of sound propagating through a test specimen wherein a signal is transmitted through a test specimen and the reflection is detected and furthermore, a through signal is detected after the signal has passed through the test specimen only a single time and utilized to provide improved automatic distance amplitude compensation.
