Abstract
A method and apparatus for reducing the acoustic coupling between a sound receiving transducer and a sound transmitting transducer is disclosed. A housing, wherein the receiving transducer and the transmitting transducer are mounted, is provided to increase the acoustic separation between the receiving transducer and the transmitting transducer. The housing has a surface, which may have an acoustic impedance condition, which is preferably resistive. The housing may further act as a barrier structure between the receiving transducer and the transmitting transducer.
