Spontaneous otoacoustic emissions in different racial groups.

Author information

Department of Otolaryngology, University of Miami Ear Institute, Florida.


To determine if there are racial differences in the prevalence of spontaneous otoacoustic emissions (SOAEs), both ears of 20 Negro, 20 Asian and 20 Caucasian subjects were examined for the presence of SOAEs. Within each racial group, equal numbers of normally hearing males and females were tested. Significant differences in the occurrence of SOAEs were found between the three racial groups, with Negroes expressing more SOAEs than Caucasians, and Asians demonstrating an intermediate number of these emissions. In support of previous observations, more emissions were recorded from female than from male ears, and a significant correlation of the number of emissions in the two ears of an individual was also noted.
