Abstract:
An array of microphones is provided wherein the microphones are positioned at the ends of cavities within a diffracting structure. The cavity depth, width, and shape are optimised to provide high directivity without grating lobes, at frequencies for which the distance between microphones is greater than half the acoustic wavelength.
