Purpose: to identify cochlear dysfunction and occurrence of tinnitus in young adults exposed to drums noise of a college band.Methods: the sample included 50 subjects: 25 musicians (study group) and 25 non--musicians (control group). The procedures included anamnesis, pure tone audiometry, acoustic impedance and Transient Evoked Otoacoustic Emissions, Distortion Product Otoacoustic Emissions and Distortion Product Otoacoustic Emissions InputOutput function.Results: positive correlation between the occurrence of tinnitus and the variables exposure time and use of personal stereos was found. Overall, the study group showed significantly lower Transient Evoked Otoacoustic Emissions, when compared to the control group. In the study group, there was a tendency toward worse response in 6 kHz(f2) in Distortion Product Otoacoustic Emissions in both ears. The Distortion Product Otoacoustic Emissions Input-Output function did not differ between groups nor did its slope.Conclusion: in general, otoacoustic emissions were worse in noise-exposed young people (study group) when compared to the unexposed (control group), indicating that the test may be important in early identification of cochlear changes.

Purpose: to obtain and compare the percentage of correct consonants rate in deaf children, cochlear implant or hearing aids users within a twelve-month interval. Additionally, the influence of aspects, such as, frequency in therapy, age at hearing impairment identification and hearing device, were also investigated in the percentage of correct consonants (PCC) index. Methods: nineteen children with hearing impairment, hearing aids or cochlear implant and were in speech therapy participated in this research. The PCC index was calculated using three tests: naming, imitation and spontaneous speech, using the phonology tasks of ABFW's -Child Language Test. The procedures were applied and reapplied within a 12-month interval, thus, characterizing a longitudinal study. Results: regarding the comparison of the PCC index, there was a statistically significant difference between the applications in all tests. An association of the average gain of percentage of correct consonants with frequency therapy was observed. Conclusion: the PCC index obtained and compared in two occasions, revealed improvement in all tasks after 12 months of speech therapy using aurioral approach. Improvement in oral production and frequency in therapy directly influenced the improvement of oral language development of these children. Improvement in oral language development of these children was directly influenced by compliance to the therapy. The age at hearing loss identification and the daily use of the devices did not influence the PCC indexes.

Além disso, buscou-se verificar a influência da frequência em terapia, da época da identificação da deficiência auditiva e do tempo de uso do dispositivo auditivo no índice de PCC. Métodos: participaram desta pesquisa 19 crianças deficientes auditivas, usuárias de Prótese Auditiva e/ ou Implante Coclear e que estavam em terapia fonoaudiológica. O índice de porcentagem de consoantes corretas foi calculado por meio de três provas: nomeação, imitação e fala espontânea utilizando as tarefas da prova de fonologia do ABFW -Teste de Linguagem Infantil. Os procedimentos foram aplicados, reaplicados e comparados, num intervalo de 12 meses, caracterizando um estudo longitudinal. Resultados: em relação à comparação do índice de porcentagem de consoantes corretas, houve diferença estatisticamente significante entre as aplicações em todas as provas. Observou-se associação do ganho médio de porcentagem de consoantes corretas apenas com a frequência em terapia. Conclusão: a partir da obtenção e comparação em duas oportunidades do índice PCC em crianças deficientes auditivas, observou-se melhora em todas as tarefas após 12 meses de intervenção fonoaudiológica com a aborgadem aurioral. A melhora do desenvolvimento d...
