Anechoic Measurements of Particle-Velocity Probes Compared to Pressure Gradient and Pressure Microphones
A number of anechoic measurements of Microflown™ particle velocity probes are compared to 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.
