[A experimental device for ultrasonic control of ear ossicle prosthesis function]

A device designed by the author is intended for functional control over prosthetic auditory ossicle efficacy in experiment. The device employs Doppler effect and lies inside the frame adjusted for the experimental conditions. The device provides standard conditions for determining amplitude-frequency characteristics and signal transmission factor in the range 128-2000 Hz. As illustration, measurements of transmission from the T-shape prosthesis are described.
