Abstract

PURPOSE: To make possible position evaluation of the case when there are evaluating parts on the same section of hollow materials by mounting 3 to 4 acoustic detectors on the same plane and detecting the sound generating sources from the differences in the arrival time of signals on assumption that the signals go along the peripheral on assumption that the signals go along the peripheral surface.
