Abstract:
A method for maximizing the radiated power of a transducer comprising the steps of:providing a transducer system comprising a transducer operating at a frequency f and having a face, a tuning fluid medium having a first medium density &rgr;1 and a first speed of sound c1, a tuning plate having a plate density &rgr;p and a thickness t, and an external fluid medium having a second medium density &rgr;2 and a second speed of sound c2; and tuning the transducer system to have a maximum specific acoustic resistance at said face in accordance with the equation: [(2&it;â€ƒ&it;Ï€&it;â€ƒ&it;f&it;â€ƒ&it;Ï p&it;t)2Ï 2&it;c2&it;Ï 1&it;c1+Ï 1&it;c1Ï 2&it;c2]&it;Ï 1&it;c1.
