Measurements on a Specific Acoustic Pulse Part 2: Measurements

  • D. R. Bacon

Abstract

This chapter describes the procedures used and the difficulties encountered when trying to measure the acoustic parameters mentioned in Chapter 6. Section 7.2 deals with the measuring instrumentation, 7.3 and 7.4 describe the measurement procedure, 7.5 deals with problems specific to calibrating continuous-wave systems and finally 7.6 discusses measurement accuracy. The whole of this chapter concentrates on measurements on a piece of equipment in a single excitation mode; Chapters 8 and 9 deal with features specific to real-time scanning devices.
