Abstract
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.
