✦ Synopsis

In this review, impedance sensors are presented as linear sensors with two entries whose signals are in#uenced by both pressure and volume velocity. Pressure is generally measured with a microphone, therefore impedance sensors are classi"ed according to the way the volume velocity is determined or controlled. The review touches on the multi-port characterization which is shown to be a generalization of impedance measurement. Finally the question of the calibration and error sources is discussed.

This paper presents an analytical investigation into the relationship between the characteristics of a linear, time-variant acoustic source, and the e!ective source impedance and source strength which follow if one then assumes the source to be time invariant. It thus models the indirect measurement
