| 摘要 |
An acoustic coupling device for a hearing screening device comprising a coupling input adapted to removeably engage a hearing screening device, the coupling input being adapted to receive an acoustic stimulus from the hearing screening device and transmit at least one response signal from a subject (or patient) to the hearing screening device; a first passive attenuator adapted to attenuate a first frequency of the acoustic stimulus; a second passive attenuator adapted to attenuate a second frequency of the acoustic stimulus, the first and second passive attenuators in combination providing a second acoustic stimulus having a substantially balanced acoustic spectrum; at least a first earpiece disposed proximate the ear canal of one of the subject's ears, the earpiece including a stimulus input adapted to transmit at least the second acoustic stimulus to the subject and receive at least a first response signal having a first volume from the subject's ear; and a response signal compensator adapted to regulate the first volume of the first response signal.
