The development of speech-in-noise perception in Hebrew-speaking school-age children

Abstract

Several studies suggest that auditory perception in general and the perception of speech in noise in particular continue to develop until late childhood or early adolescence. It remains unclear, however, whether this prolonged development results from the maturation of the cognitive factors associated with the performance of auditory tasks or from the slow development of auditory sensory processing. We investigated the perception of monosyllabic words embedded in white noise in Hebrew-speaking school-age children and adults. Although identification thresholds did not become adult-like until 11 years of age, we found no evidence linking this prolonged development to non-sensory factors associated with performance consistency. Therefore, we suggest that similar to the development of amplitude and frequency modulation detection thresholds, this protracted development is related to the maturation of auditory sensory processing.
