  • Loading probe for testing an acoustic transducer
    Patent number: 6829929
    Abstract: A loading probe includes an elongated solid first body portion (1) shaped from a first material and capable of simulating the normal acoustic impedance presented to a transducer to be tested by a medium in which the transducer is to operate and a second elongated solid body portion (2) made from an acoustically absorbent material having acoustic impedance characteristics substantially matched with those of the first material from which the first body portion (1) is made. The material from which the second body portion (2) is made is chosen so as to be mouldable to the first body portion (1) to form the second body portion (2).
