Abstract

Open-spherical acoustic intensity probes are microphone arrays based on the Kirchhoff-Helmholtz integral and are used in the measurement of active acoustic intensity. The acoustic intensity measurements obtained by these arrays can be used to localise sound sources. Previously, the performance of these arrays in acoustic free field conditions were obtained using numerical simulations and it was shown that they provide better performance than other types of probes. This paper discusses the implementation of open spherical microphone arrays and their performance in reverberant enclosures.
