Summary

Chapter 12 describes the contemporary measurement methods in duct acoustics. Acoustic measurements are necessary in order to validate theoretical models and also to develop acoustic models when theoretical approaches tend to be inadequate or impossible. The multiple wall-mounted microphone method is introduced from first principles and its applications to the measurement of the characteristics of acoustic sources and of passive system elements are described.
