Abstract

In order to investigate the influence of the sound intensity probe itself on the accuracy of measurement, a diffraction of the plane progressive wave by two finite-length cascade cylinders is calculated by the boundary element method (BEM). The sound pressure distribution around the cylinders is compared with the measured one. Both results agree well with each other. Frequency characteristics of the force that acts on the surface facing the gap between two cylinders are calculated for various probe model geometries. The force response shows deviations at high frequencies where the probe size becomes comparable to the wave length. This deviation mainly depends on the diameter of the probe.
