Otoacoustic Emissions in Smoking and Nonsmoking Young Adults
... One of the most sensitive tests of hearing is otoacoustic emissions (OAEs), which are low-level sounds originating in the cochlea which can be measured in the ear canal [8]. OAEs require the proper functioning of outer hair cells [9]. Because OAEs are very sensitive to cochlear abnormalities [10], ...
