Title: Digital filter design for compensating the nonlinear behavior of sound intensity probe
Abstract: The paper addresses a problem of the measurement of an acoustic energy flow using the sound intensity pressure-velocity probes. Nowadays this technique has become more and more popular in a modern research of the acoustic field. Using a so called 3D SI probe there is possible to visualize the sound energy flow of real sources in real objects. In the paper the metrological problem of the amplitude and phase frequency characteristics compensation of the transducers of acoustic quantities is presented, what is crucial for the sound intensity probes. The compensation routine using digital filter is proposed as an alternative to analog compensation and digital routine in frequency domain. The routine will be included in the postprocessing block of the fully automated sound intensity measurement system.
