چکیده

UNLABELLED Much has been studied on the role of the acoustic reflex in the communication process. AIM To examine the responses of the contralateral acoustic reflex in children with normal hearing and phonological disorders. To investigate the relationship of the level of severity of phonological disorder. To measure the chances of it affecting all the frequencies tested. MATERIALS AND METHODS The study was based on the analysis of medical charts from 70 children with phonological disorders, and 24 females and 46 males, aged between 5 and 7 years. Audiological tests were analyzed to exclude children with hearing loss, evaluation of the contralateral acoustic reflex and the level of severity of phonological disorder. STUDY DESIGN Prospective. RESULTS All children showed change in the contralateral acoustic reflex. There was no significant relationship between the level of severity of phonological disorders and changes in the acoustic reflex for both genders. Female children showed no statistically significant value in the relationship between the frequencies, except at 500 Hz. Male children had more significant relationship in the association between changes in frequencies tested. CONCLUSION It is believed that children with phonological disorders exhibit changes in the contralateral acoustic reflex.

Efferent auditory system: its effect on auditory processing.

UNLABELLED Auditory processing depends on afferent and efferent auditory pathways integrity. The efferent auditory system may be assessed in humans by two non-invasive and objective methods: acoustic reflex and otoacoustic emissions suppression. AIM Analyze the efferent auditory system activity by otoacoustic emission suppression and acoustic reflex sensitization in human subjects with audito...

Establishment of Phonological Contrasts among Fricatives by Children with a Phological Disorder: Acoustic Cues Manipulation

• ABSTRACT: The present study focuses on the presence of covert contrasts in the speech of children with a phonological disorder. The hypothesis is that children with phonological disorders manipulate secondary acoustic cues in an attempt to distinguish the phonological contrasts. We used five audio recordings of the speech of five children with speech disorders, between four and five years of ...
