摘要：A system and method for measurement of ear conditions utilizing a test signal. The apparatus includes a wave guide having a proximal and distal end. The distal end is connected to a probe tip, which may be fabricated of a semi-rigid material or rigid material and may further be a material transmissive light. The probe tip is sized so as to fit at least a portion of the probe tip within the ear canal. The wave guide further includes an acoustic energy source disposed substantially at the proximal end for generating a test acoustic wave in response to a source signal. The wave guide further includes an acoustic energy detector, for example a microphone, for detection of reflected acoustic energy and generation of a electrical signal in response. The apparatus is controlled by a processor. The processor is adapted to generate the source signal which will preferably contain pseudo-random noise. The processor is further adapted to receive the detected signal from the acoustic energy detector and to generate an condition signal related to the ear condition in response to the detector signal and the source signal. The condition signal may be utilized to control a video display, a printout device, or any other device capable of conveying to the operator the ear condition. The apparatus may be further adapted to view the car while testing by including a lens at the proximal end and a light source toward the distal end of the wave guide. Also disclosed is a method for measurement of ear conditions.
