The long-term goal of the Auditory Processing Laboratory is to develop clinical tools that determine the site and extent of lesions in the peripheral auditory system that creates hearing loss. The research explores how hearing loss is caused by damage to a variety of cochlear and neural structures.

Because diagnostic procedures are not designed to identify the locus of lesion or amount of damage to structures within the cochlea or auditory nerve, it's important to identify the location and severity of damage to cochlear and neural structures for developing remediation strategies to cure hearing loss, including neural tissue transplantation and cellular regeneration.

Researchers record electrophysiological signals such as cochlear microphonics and compound action potentials in both animal and human models. Through modifications of the acoustic signal and signal processing strategies applied to the physiologic responses come the development of indices to identify the locus of lesion and the health or pathophysiology of the remaining anatomical structures.
