Abstract
The acoustic compass is an alternative technique such that a group of microphones arranged in some specific configuration for noise source localization on the azimuthal plan. The signal processing for the acoustic compass relies on cross-correlation function that allows the device to obtain good performance in broad frequency ranges. This paper discusses on geometrical design of the acoustic compass and its background in signal processing technique. In this work, an acoustic compass was designed, built, and tested in an open-air site. The performance is evaluated by mean of the SNR, the distance of the source, and the accuracy of localization.
