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.
La présente divulgation traite d'une méthode et d'un dispositif permettant de réduire le couplage acoustique entre un transducteur de réception sonore et un transducteur de transmission sonore. Un boîtier, dans lequel sont installés le transducteur de réception et le transducteur de transmission, permet d'augmenter l'isolation acoustique entre le transducteur de réception et le transducteur de transmission. Ce boîtier comprend une surface qui peut présenter une condition d'impédance acoustique, de préférence résistive. Le boîtier peut servir plus tard de structure de blocage entre le transducteur de réception et le transducteur de transmission.
