Characterization Study of Using Acoustic Signals for Underwater Non-Destructive Testing

Non-destructive testing in structural inspection is a list of techniques that is used to evaluate the condition of a structure in order to determine whether cracks, flaws defects or damages occur in structural build without causing any damage to the test object. This work presents the characterization study of using acoustic signals for underwater non-destructive testing. The optimum operating frequency for sensors, transmission angle between the transmitter and receiver and operating distance between the sensors with reflecting medium are determined. Early results can be implied in exploring the possibility of using acoustic signals in underwater structural inspection with non-destructive testing methods.
