ObjectivesContralateral masking of transient-evoked otoacoustic emissions is a phenomenon that suggests an inhibitory effect of the olivocochlear efferent auditory pathway. Many studies have been inconclusive in demonstrating a clear connection between this system and a behavioral speech-in-noise listening skill. The purpose of this study was to investigate the activation of a medial olivocochlear (MOC) efferent in children with poor speech-in-noise (PSIN) performance and children with language impairment and PSIN (SLI+PSIN).MethodsTransient evoked otoacoustic emissions (TEOAEs) with and without contralateral white noise were tested in 58 children (between 6 and12 years). These children were arranged in three groups: typical development (TD) (n=25), PSIN (n=15) and SLI+PSI (n=13).ResultsPSIN and SLI+PSI groups presented reduced otoacoustic emission suppression in comparison with the TD group.ConclusionOur finding suggests differences in MOC function among children with typical development and children with poor SIN and language problems.
