AUDIOLOGIC TEST APPARATUS AND METHOD

摘要

An audiologic test apparatus includes: a pump device configured to apply a first pressure to the ear canal; and a processing module for communicatively coupling to the pump device and to a signal generator, wherein the processing module is configured to obtain first acoustic parameter values indicative of an acoustic parameter at the first pressure based on a first broadband signal generated using the signal generator; wherein the pump device is configured to change the first pressure to a changed pressure, and wherein the pump device is also configured to apply a second pressure to the ear canal; and wherein the processing module is also configured to obtain second acoustic parameter values indicative of the acoustic parameter at the second pressure based on a second broadband signal generated using the signal generator, and determine a middle ear resonance frequency based on the first and second acoustic parameter values.

1. An audiologic test apparatus comprising:
a pump device for fluidic communication with an ear canal of a subject, wherein the pump device is configured to apply a first pressure to the ear canal; a signal generator; and a processing module for communicatively coupling to the pump device and the signal generator, wherein the processing module is configured to obtain first acoustic parameter values indicative of an acoustic parameter at the first pressure based on a first broadband signal generated using the signal generator; wherein the pump device is configured to change the pressure in the ear canal from the first pressure to a second pressure, and apply a third pressure to the ear canal; wherein the signal generator is configured to generate a first tone signal during the pressure change from the first pressure to the second pressure; and wherein the processing module is configured to obtain third acoustic parameter values indicative of the acoustic parameter at the third pressure based on a third broadband signal generated using the signal generator, and determine a middle ear resonance frequency based on the first acoustic parameter values and the third acoustic parameter values.
