Heide, Au.D. Audible Difference [email protected] 608.273.3036 Advisor: Mitchell E. Tyler, P.E., M.S. Dept. of Biomedical Engineering & Dept. of Ortho-Rehab Medicine University of Wisconsin - Madison [email protected] 608.265.3756 Problem Statement: The goal is to design and develop an auditory substitution device that through the use of vibrotactile stimulation can substitute for regional frequency hearing loss. We will continue the work from the last three semesters, mainly focusing on refining the technical operation of the prototype and obtaining clinical testing data on the performance of the system.
