ABSTRACT
Otoacoustic Emissions (OAEs) are non -invasive, quick and objective methods to access the function of a cochlear and screen the children’s hearing. Recently, DPOAE latencies have been considered to be related to the progressing of the traveling wave along the basilar membrane. It may also reflect the function of the cochlear. The aim of this study was to investigate if the latency measures could be efficiently used for screening people with normal hearing and with conductive hearing loss. For this purpose, DPOAE latencies were measured as a function of frequency from 1 to 8 kHz with frequency ratio f2/f1=1.22 in 22 normal preschool children and 23 ears with conductive hearing loss (mild effusion). The results were as follow:There was a significant difference in latency between ears with normal hearing and with Middle ear effusion (MEE) as a function of frequency. The mean value of DPOAE latency for normal ears was significantly lower than that of ears with conductive hearing loss except 8 kHz (p<.05). There was no gender effect in latency for most frequencies except 1 kHz.
Key Words: DPOAEs·MEE.
중심단어: 변조이음향방사· 삼출성중이염.
