Gender Effects on High Frequency Distortion Product Otoacoustic Emissions in Humans

Abstract

Gender-based norms for auditory-evoked potentials measures are standard in clinical settings. The results of the present study, in agreement with previous studies, indicate that significant interactions exist between gender and DPOAE group delay values in the lower frequencies, and between gender and DPOAE levels at the higher frequencies. To reach the goal of using high frequency DPOAEs in clinical protocols, such as for auditory neuropathy/dys-synchrony diagnosis and ototoxicity monitoring, DPOAEs elicited with conventional and higher frequency stimuli must be understood, including the role of gender to determine if an effect on clinical protocols would exist.

Distortion-product otoacoustic emissions in the common marmoset (Callithrix jacchus): Parameter optimization

“…Dunckley and Dreisbach, 2004), and other animals (e.g. frogs: Vassilakis et al, 2004;rhesus monkeys: McFadden et al, 2006a).…”

“…The sex differences we have reported seem to be the largest reported in primates thus far. In humans, Dunckley and Dreisbach (2004) investigated sex differences in L DP (with L 1 = 60 dB SPL, L 2 = 45, and f 2 /f 1 = 1.22) and showed that the absolute difference in the mean L DP (mean female L DP -mean male L DP ) ranged from À5.46 dB SPL (at 9 kHz) to 6.07 dB SPL (at 13 kHz) and the mean difference in L DP was reported to be 2.08 dB SPL. In marmosets, the absolute difference in mean L DP , with 62 dB SPL (equilevel) tones, ranged from 3.45 to 11.8 dB SPL (mean = 6.20 dB SPL).…”

High frequency distortion product otoacoustic emissions in children with and without middle ear dysfunction

“…The findings in adult subjects with normal middle ear function, however, showed that the DPOAE amplitude decreased for f 2 frequencies greater than 10 kHz [12]. In another study, the DPOAE level obtained from normally hearing adults decreased with increasing f 2 frequency up to 15 kHz [13].…”

“…As children undergoing chemotherapy may also have middle ear problems, it is necessary to know if middle ear problems would have a confounding effect on the ability of DPOAEs to assess cochlear function in the extend high frequency region (9)(10)(11)(12)(13)(14)(15)(16). The present study aimed to investigate the effect of middle ear dysfunction on DPOAEs in the extended high frequency region in young children.…”

“…In a study about high frequency otoacoustic emissions, Dunckley and Dreisbach (2004) 20 did not find significant differences between male and female subjects, but they considered important to determine what is the effect of gender on DPOAE measurements and how these differences can affect the measurements in clinical use of emissions.…”
