The Relationship between Mean Length of utterance (MLU), Lexical Richness and syntactical and lexical metalinguistic Awareness in Bilingual (Turkish-Persian) normal and hearing impaired Children Objectives: Regarding the impact of hearing loss on language development and metalinguistic skill and being language development different from metalinguistic skill in bilingual children, studying of...
Distortion product emissions (DPEs) at 2f1 f2 frequencies were measured in 53 human ears; 21 of them exhibited cochlear hearing loss. DPEs were obtained as a function of stimulus level (DPE growth curves) at seven frequency regions between 707 Hz and 5656 Hz. Several distinctly different shapes or patterns of DPE growth curves were observed. These included single-segment monotonic growth curves...
introduction: tinnitus is a perception of sound without external source. the exact etiology of tinnitus is not fully understood, although some researchers believe that the condition usually starts in the cochlea. the aim of this study was to determine the potential contribution of outer hair cell dysfunction to chronic tinnitus, by application of distortion-product evoked otoacoustic emission (...
Background: Cortical Evoked Response Audiometry (CERA) refers to prediction of behavioral pure-tone thresholds (500-4000 Hz) obtained by recording the N1-P2 complex of auditory long latency responses. CERA is the preferred method for frequency–specific estimation of audiogram in conscious adults and older children. CERA has an increased accuracy of determination of the hearing thresholds of ale...
Objectives: Phonemic awareness skills have a significant impact on children speech and language. The purpose of this study was investigating the phonemic awareness skills of children with cochlear implant and normal hearing peers in primary school. Methods: phonemic awareness subscales of phonological awareness test were administered to 30 children with cochlear implantation at the first to ...
Objective: The aim of the present research was to compare the auditory perception and verbal intelligibility in children with cochlear implant, hearing aids and normal hearing. Methods: 60 children aged 5-7 years were divided to three groups and each group contained 20 children. The first and second groups were selected ordinarily from children with cochlear implant and hearing aids by conve...
abstract introduction: conductive hearing loss attenuates and delays sound transmission in the middle ear. it can make variety of central auditory processing disorders; that persists even after resolve of peripheral auditory system problems. one of the aspects of central auditory processing is the temporal processing, which is important for understanding speech, including temporal resolution,...
