Auditory filter measurements

Researcher(s): L. Körössy, E.E. , T.E.M. van Esch, MSc.
Supervisor(s): prof. W.A. Dreschler, PhD.

Background:
The broadening of auditory filters is a typical characteristic of sensorineural hearing loss. Due to this broadening, the frequency resolution of the ear declines. Not all hearing impaired people show the same patern of broadening of the auditory filters. Therefore it is interesting to measure these filter characteristics.

Aim:
To implement a clinical relevant measurement method for auditory filter characteristics, developed by Leeuw and Dreschler.

Method:
The existing adaptive procedures, methods and processes will be translated to software objects. Using computer controlled measurement equipment (Tucker Davis Technology) the measurement method will be implemented.

Results:
The implementation functions correctly and is successfully tested with normal hearing subjects. Filter characteristics meet the results found in literature.

Future Research:
The implementation will be extended with measurements for multiple frequencies and intensities. The clinical implementation will be studied. The expertise on auditory filter measurements will be contributed to the HEARCOM-project.
