    Patent number: 6068590
    Abstract: A device for diagnosing and treating hearing disorders including a supersonic transducer which has a resonance frequency in the supersonic range. The transducer includes a piezoelectric ceramic tube which is compressed between a head mass and an inertial mass. A tensioning rod extends between the masses and is threadedly engaged with a nut which tensions the rod to adjust the compression on the ceramic tube. A tuning circuit can be used to increase the band width at resonance.
