Adjunct Professor Harvey Albert DILLON, Turramurra NSW 2074

For distinguished service to science, and to engineering, as a researcher in the field of hearing loss assessment, electrophysiology, and rehabilitation, and to improved auditory technologies. 

Dillon is the former director of the Australian National Acoustic Laboratories (NAL) and co-creator, with Denis Byrne, of the Client Oriented Scale of Improvement (COSI), a NAL questionnaire designed to evaluate client needs, goals, and improvements in hearing ability.

He has researched and published extensively in scientific journals, including several articles he co-wrote for Hearing Review on the NAL approach to hearing aids for patients who wear cochlear implants in the opposite ear; narrow directionality features; and survey results on perceptions of self-adjustable hearing aids. In addition to his publications, Dillon is a well-known lecturer on complex audiological topics, and the second edition of his textbook Hearing Aids, has become a standard reference for audiology students, teachers, and educators.

In 2003, Dillon received a Research Achievement Award from the American Academy of Audiology (AAA), which is given to an individual whose work in audiology/hearing research has made significant impact on the field or practices.
