Background/Aim. Initial experiences in rehabilitation of children with cochlear implants and frequent debates regarding the effects of their application have imposed the necessity to compare the effects of speech rehabilitation in children with hearing aids with those having cochlear implants. The aim of this study was to evaluate and compare the level of lexical development in hearing impaired children who are involved in the process of hearing and speech-language rehabilitation and who were amplified by hearing aids or cochlear implants. Methods. The sample consisted of 55 children aged 3?6 years, diagnosed with prelingual bilateral hearing impairment with a hearing threshold above 90 dB. All examined children had average intellectual abilities and no additonal impairments. The sample was divided into 2 groups: E1 group consisted of 30 children with cochlear implants and E2 group consisted of 25 children who were amplified by individual hearing aids. Research methodology included a Test of Vocabulary. The testing was performed individually. A year after the testing, a retest was done. Statistical analysis was performed using the SPSS v. 17 for Windows. Results. The largest number of children had average achievements on a Test of Vocabulary during initial testing. After a year (retest) significant improvements were noticed. A large number of children had above average achievements (46.7% in the E1 and 36% in the E2 group) while the number of children with below average achievements was significantly reduced (3.3% in the E1 and 8% in the E2). A comparative analysis of the test and those with gearing aids achievements showed that there was no statistically significant difference between children with cochlear implants and retest. Conclusion. Significant improvement of the achievements on retest in both groups can be explained by positive effects of systematic, planned, intensive and continuous rehabilitation of hearing impaired children, and not by application of certain type of hearing amplification.

Phonological Processes are simplification of sounds which occur among the children during the younger age and will gradually diminish giving an adult like speech form. The aim of the present study is to analyze the occurrence of phonological processes among hearing impaired children who underwent cochlear implant surgery during their younger age as an early intervention. The subjects included in the study were 10 children (5 male and 5 female) who were diagnosed with congenital total hearing impairment and underwent cochlear implant surgery and attending Auditory verbal therapy. The task given to the subjects in the present study is to repeat the words in Tamil Articulation Test followed by the Clinician. The words were recorded and further analyzed for the occurrence of phonological processes. The results show that a total of 26 phonological processes (both typical and atypical) occurred with a maximum occurrence of Depalatalization and minimally of Final Consonant Deletion. The results of the present study help in providing a better knowledge about the occurrence of phonological processes which helps the speech language pathologist in intervening hearing impaired children with cochlear implants and to improve their speech intelligibility.

Introduction: Hearing is essential to learn language and speech and to develop cognitive skills. According to World Health Organisation (WHO), world-wide approximately 350 million people have hearing disorder. The performance of some moderately severe hearing-impaired adults and children using hearing aids is poorer than that of even profoundly hearing-impaired individuals using cochlear implants with advanced speech processing strategies. Aim: To find out the appropriate candidates in need of cochlear implantation in Prayagraj district of Uttar Pradesh, India. Materials and Methods: This cross-sectional study was conducted on hearing impaired patients attending Ear Nose Throat (ENT) Out Patient Department (OPD) of tertiary health care center in Prayagraj Uttar Pradesh from August 2011 to July 2012. The study population consisted of 95 patients categorised into four groups (pre-lingual children and adults, post-lingual children and adults) who presented with the chief complaints of impaired hearing and delayed speech. A detailed history, clinical and other relevant systemic examination and investigations were done. Patients were subjected to free field audiometry, pure tone audiometry and Brainstem-Evoked Response Audiometry (BERA) for assessment of hearing threshold level. Patients used hearing aid for six months and after hearing aid use, their hearing threshold and speech discrimination scores were estimated. Patients, whose aided score on open-set sentence test was less than 50%, were selected as candidate for cochlear implants, as they were not significantly benefited by hearing aids. Results: Out of the 95 cases, 48 were found to be suitable for cochlear implantation, which formed 50.5% of the study group. Pre-lingual hearing impaired adults had the highest percentage i.e., 86.7%, fulfilling the criteria for cochlear implantation followed by pre-lingual children, in whom 46.7% fell in this category. A 26.7% of postlingual children and 20% of postlingual adults were found suitable for cochlear implantation. Conclusion: The pre-lingual hearing impaired children and adults are more in need for cochlear implantation than the postlingual hearing-impaired children and adults. Approximately, 134,501 cases were estimated to be, in need of cochlear implantation in Prayagraj district based on the census estimate of 2011.

A commercial noise dose meter was used to estimate the equivalent noise dose received through high-gain hearing aids worn in a school for deaf children. There were no significant differences among nominal SSPL settings and all SSPL settings produced very high equivalent noise doses, although these are within the parameters of previous projections.

The identification of consonants in a/-C-/a/nonsense syllables, using a fourteen-alternative forced-choice procedure, was examined in 4 profoundly hearing-impaired children under five conditions: audition alone using hearing aids in free-field (A),vision alone (V), auditory-visual using hearing aids in free-field (AV1), auditory-visual with linear amplification (AV2), and auditory-visual with syllabic compression (AV3). In the AV2 and AV3 conditions, acoustic signals were binaurally presented by magnetic or acoustic coupling to the subjects' hearing aids. The syllabic compressor had a compression ratio of 10:1, and attack and release times were 1.2 ms and 60 ms. The confusion matrices were subjected to two analysis methods: hierarchical clustering and information transmission analysis using articulatory features. The same general conclusions were drawn on the basis of results obtained from either analysis method. The results indicated better performance in the V condition than in the A condition. In the three AV conditions, the subjects predominately combined the acoustic parameter of voicing with the visual signal. No consistent differences were recorded across the three AV conditions. Syllabic compression did not, therefore, appear to have a significant influence on AV perception for these children. A high degree of subject variability was recorded for the A and three AV conditions, but not for the V condition.
