Abstract : The patent describes an improved bearing deviation indicator for detecting and tracking noise sources such as, for example, those produced by vehicles. The device comprises a rotatable acoustic array which generates electrical analogs of the noise waves which are coupled to novel signal processing means which produce signals indicative of alignment of the acoustic array with the noise source or deviation of the acoustic array from the noise source. The signals are coupled to servo means which in response thereto rotates the array to align it with the noise source.
