Measurement and visualization of sound intensity vector distribution in proximity of acoustic diffusers
Abstract
In this work, we would like to present analyses and visualizations of sound intensity distribution measured in proximity of an acoustic diffuser. Such distribution may be used for estimation of basic acoustic parameters of a diffuser. Measurement is performed with the use of a logarithmic sine sweep which allows for the analysis of waves scattered by the diffuser and rejecting the direct sound signal component. Pressure and sound intensity vector impulse responses are measured simultaneously. The measurement is carried out for a grid of 37 points arranged at equal intervals lying in a semicircle. To investigate the impact of objects evaluated on the sound wave propagation diffusion coefficients and sound intensity vector distributions are then compared.
