ACOUSTIC MATCHING MATERIAL, METHOD OF MANUFACTURE THEREOF, AND ULTRASONIC TRANSMITTER USING ACOUSTIC MATCHING MATERIAL

摘要

An acoustic matching material (1) is used to match the acoustic impedance of a first object to that of a sound object when sound is transmitted from the first object to the second object. The acoustic matching material (1) includes a plurality of minute pieces (2), at least one of which is coupled to another piece (2) to form a gap in the acoustic matching material (1).
