Abstract : The patent describes a directional detection system including a microphone assembly comprising an omnidirectional microphone and two orthogonal directional microphones. The object is to provide an acoustic detector which locks onto a spectral component of a broadband signal oscillating in a predictable bandpass, producing a phase angle signal indicative of the direction of propagation of the spectral component.
