    摘要: A hearing test device is capable of presenting a variety of acoustical or vibratory stimuli and can be easily calibrated. Transfer functions for the device are calculated at two different attenuation levels to derive the characteristic impedance and sensitivity of the acoustic or vibratory transducer. The predicted sound pressure level emitted by the transducer may then be calculated as a function of input signal and attenuation.
