Dr. Navid Shahnaz is currently an Associate Professor of Audiology in the School of Audiology & Speech Sciences at the University of British Columbia (UBC), where he has been a faculty member since July 2002. He has been a Speech-Language and Audiology Canada (SAC) certified member since November 1995. He was a member of the national (CASLPA) Audiology Examination Committee between 2002 and 2008, and a member of the CASLPA Board of Governors (2011-2014), where he was the representative of the Canadian Council of University Programs in Communication Sciences and Disorders. His main area of research interest includes multi-frequency tympanometry, Wideband Acoustic Immittance, otoacoustic emission, and acoustic reflex studies in adults, children, and infants. His new research interests also focus on the assessment of the balance systems using vestibular evoked myogenic potentials, and the development of test batteries for assessment of the silent (hidden) hearing loss.

Dr. Shahnaz’s main areas of research interest include multi-frequency tympanometry, Wide Band Energy Reflectance, otoacoustic emission, and acoustic reflex studies in adults as well as newborns. He is also interested in effect of personal listening devices (iPods) on hearing. Other areas of research interests are extended high frequency thresholds estimation in different ethnic groups and cochlear dead region.
