摘要

A number of anechoic measurements of Microflown(TM) particle velocity probes are compared to the measurements of pressure-gradient and pressure microphones made under identical acoustical conditions at varying distances from a point source having a wide frequency range. Detailed measurements show specific response changes affected by the distance to the source, and focus on the importance of transducer calibration with respect to distance.
