ータ。A sound wave generator 1 that outputs sound wave energy of a specific frequency toward the inside of the middle ear canal, a pressure variable device 4 that changes the pressure inside the ear canal, a pressure detection device 5 that converts the pressure inside the ear canal into an electrical signal, and a pressure detector 5 that converts the pressure inside the ear canal into an electrical signal. a sound pressure detection device 6 that converts the reflected sound wave output into an electrical signal; a compliance conversion device 12 that converts the sound pressure signal detected by the sound pressure detection device 6 into a compliance signal; and a compliance conversion device 12 that converts the sound pressure signal detected by the sound pressure detection device 6 into a compliance signal; A storage device 13 that simultaneously inputs the pressure signal and the compliance signal output from the compliance conversion device 12 and stores it as the compliance of the middle ear with respect to the atmospheric pressure, a display device 16 or a recording device 17 that displays the output signal. In the impedance audiometer, the maximum value of the compliance signal output from the compliance conversion device is compared with a preset value, and a signal is output when the value of the compliance signal is larger than the preset value. a comparison circuit 14 that receives the output signal thereof, and a sensitivity switching device 15 that switches the sensitivity of the output signal from the storage device 13 and outputs the output signal, and sends the output signal to the display device 16 or the recording device 17. An impedance audiometer.
