Audiologic test apparatus and method

An audiologic test apparatus comprising:

• a pump device for fluidic communication with an ear canal of a subject, the pump device configured to apply a first pressure to the ear canal, change the pressure in the ear canal from the first pressure to a second pressure and apply a third pressure to the ear canal;
• a signal generator configured to generate a first tone signal during the pressure change from the first pressure to the second pressure;
• and
• a processing module for communicatively coupling to the pump device and the signal generator, the processing module 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, second acoustic parameter values indicative of the acoustic parameter at the second pressure based on a second broadband signal using the signal generator and third acoustic parameter values indicative of the acoustic parameter at the third pressure based on a third broadband signal generated using the signal generator;
• whereby the processing module determines a middle ear resonance frequency from a baseline compensated admittance based on the first acoustic parameter values and the third acoustic parameter values;
• and
• wherein the processing module is configured to determine a first tympanogram based only on the first tone signal generated using the signal generator, and wherein the processing module is configured to determine the third pressure based only on the first tympanogram, the third pressure being between the first pressure and the second pressure.
