Hydrophone-Based Measurements on a Specific Acoustic Pulse Part 1: Field Characterisation

  • R. C. Preston


This chapter deals with the use of a hydrophone to measure and characterise a single acoustic pulse or a sequence of identical acoustic pulses generated by an ultrasonic transducer. Later chapters deal with the extension of these basic techniques to cope with more complex ultrasonic fields such as those generated by ultrasonic scanners.
