Otoacoustic emissions are an essential part of the audiology test battery, especially for patients who cannot appropriately respond during subjective tests. Otoacoustic emissions provide information regarding the function of the inner ear, specifically the outer hair cells within cochlea. This testing has been done previously in canines in laboratory settings and has shown to accurately diagnose hearing loss in canines verified by brainstem auditory evoked response. There are currently no established protocols, which means no clinical normative data could be established and utilized. The purpose of this project was to review the use of otoacoustic emissions in humans and canines and to discuss factors that could affect otoacoustic emissions in canines to assist in establishing a proposed protocol. This project found otoacoustic emissions are a reliable way to assess hearing of canines and can be used as a screening tool or as part of a diagnostic battery.
