Abstract
The present invention relates to a sound separating system for separating signals such as intelligible sound, for example, speech, from unwanted noise, such as random noise, when both the noise and the intelligible speech sound are present in an acoustical field and the intelligible speech sound is provided from a source located within the acoustical field. The system comprises a first and second sensing transducer located within the field which both pick up both the intelligible speech sound and the noise. Each sensing transducer generates a representative output signal. The two sensing transducer are in close proximity to each other and the intelligible sound is correlated at said first and second sensing means relative to the sound's source.
