Design and validation of an ear canal simulator for EVestG Evaluation
The proposed research is to design, develop and validate an artificial ear-canal that simulates the electrical noise conditions that exist when taking EVestG measurements by associated bio-signal amplifiers. Such a simulator will allow the rapid, rational and accurate refinement of such amplifiers and tympanic electrode; it will also allow improvements to be made to the developed signal extraction software algorithms. Furthermore a more qualitative approach to identifying good from poor recordings when evaluating various operational scenarios will be investigated, which subsequently will be translated to best practices in EVestG Clinical Measurement protocols. Once the artificial ear-canal is constructed, ultra low noise bio-signal amplifiers (made by the industrial partner) tailored for EVestG can be evaluated and qualitative comparisons with the currently used OEM amplifier will be conducted.
