RESUMO Introdução:A resolução temporal é a percepção de um intervalo de tempo em que o indivíduo discrimina dois sons sendo uma habilidade envolvida na música. Objetivo:Identificar o desempenho da resolução temporal em músicos violinistas e não músicos e correlacioná-lo à média dos limiares das frequências graves e agudas, bem como, ao tempo de exposição diária à música. Método:O presente estudo caracterizou-se por ser prospectivo e comparado entre dois grupos, sendo um composto por 20 músicos violinistas e outro por 20 não músicos semi pareados por idade e escolaridade que foram submetidos à avaliação audiológica e ao teste Gaps In Noise (GIN), para avaliar a resolução temporal. Resultados:O desempenho do teste GIN do grupo de músicos não foi significativo em relação ao grupo controle seja na orelha direita (OD) ou na esquerda (OE). A correlação entre a média das frequências agudas para OE com o teste GIN foi (p=0,001) no grupo controle. A média das frequências graves para ambas as orelhas no grupo de músicos foi estatisticamente significativa sendo os maiores valores para OD (p=0,001). Conclusão:Não houve diferença entre o desempenho do teste GIN para ambos os grupos assim como a correlação entre o tempo de exposição diária a música e o GIN. O limiar audiométrico das frequências agudas mostrou-se relevante na realização do teste GIN. Palavras-chave: música, limiar auditivo, percepção auditiva. SUMMARY Introduction:The temporal resolution is the perception of a time interval in which the individual discriminates two sounds being a skill involved in music. Objective:To identify the performance of temporal resolution in musicians and no musicians violinists and correlate it with the average of the thresholds of low frequencies and acute as well as the time of exposure to music daily. Method:This study was characterized by be prospective and compared between two groups, one consisting of 20 violinists and other musicians for 20 semi no musicians matched for age and education were submitted to audiological evaluation and to the test Gaps In Noise (GIN) to evaluate the temporal resolution. Results:The test performance of the GIN group of musicians was not significant in the control group is in the right ear (RE) or left (LE). The correlation between the average high frequencies for the LE with the GIN test was (p = 0.001) in the control group. The average frequencies for both ears in the group of musicians was statistically significant and the highest values for RE (p = 0.001). Conclusion:There was no difference between the performance of the GIN test for both groups as well as the correlation between duration of daily exposure to music and GIN. The audiometric threshold of high frequencies seemed to be relevant for testing GIN.

Introduction:The agricultural airplane pilot are daily exposed to intense noises, being susceptible to the noiseinduced hearing loss (NIHL) and its auditory and extra auditory effects. Objective:To analyze the audiological profile of this population, verifying the work's influence on its hearing. Method:It was realized a retrospective, individual, observational, and cross-sectional study through the data obtained by means of a questionnaire and audiometric thresholds of 41 agricultural pilots. To the statistical analysis were utilized the chi-square, Spearman, and Wilcoxon tests with significance level of 5%. Results:It was verified that 95,1% of the pilots use PPE ( personal protective equipment) during flight and 58,5% have contact with pesticides. More than half of individuals referred to feel auditory and extra auditory symptoms, being the buzz the more frequent (29,1%). It has the occurrence of 29,3% of NIHL suggestive hearing loss and 68,3% of normality, taking this presence of unilateral notch in 24,4% and bilateral notch in 31,7%. It was found correlation statistically significant in the associations between time of service and the average of the acute frequencies in the right ear (p=0038), and in the left ear (p=0,010). It has a statistical tendency in the association between audiometric configuration and contact with pesticides (p=0,088). Conclusion:The hearing loss prevalence in this study was showed high. More than half of the sample has normal audiometric thresholds with notch configuration. Such data lead to the conclusion that the agricultural pilots, even with PPE use, they still suffer with the damages caused by noise, needing best proposals of hearing loss prevention. RESUMO Introdução:Os pilotos de aviões agrícolas estão diariamente expostos a ruídos intensos, estando suscetíveis à Perda Auditiva Induzida pelo Ruído (PAIR) e seus efeitos auditivos e extra-auditivos. Objetivo:Analisar o perfil audiológico desta população, verificando a influência do trabalho sobre sua audição. Método:Foi realizado um estudo retrospectivo, de corte transversal, individual e observacional, através de dados obtidos por meio de questionário e audiometria tonal liminar de 41 pilotos agrícolas. Para a análise estatística foram utilizados os testes Qui-quadrado, Spearman e Wilcoxon, com nível de significância de 5%. Resultados:Verificou-se que 95,1% dos pilotos usam EPI durante os vôos e 58,5% possuem contato com agrotóxicos. Mais da metade dos indivíduos referiram ter sintomas auditivos e extra-auditivos, sendo o zumbido o mais frequente (29,1%). Houve a ocorrência de 29,3% de perda auditiva sugestiva de PAIR e 68,3% de normalidade, tendo, esta, presença de entalhe unilateral em 24,4% e entalhe bilateral em 31,7%. Foi encontrada correlação estatisticamente significativa nas associações entre tempo de serviço e a média das frequências agudas na orelha direita (p=0038) e na orelha esquerda (p=0,010). Houve tendência estatística na associação entre configuração audiométrica e contato com agrotóxicos (p=0,088). Conclusão:...

Introduction:The ability of temporal sequencing refers to the processing of two or more auditory stimuli in order of occurrence in time. Objective:To compare the skill of sequencing between musicians and non-musicians violinists from the frequency pattern test (FPT). Method:The prospective, constituted a group of 20 violinists and musicians non-musicians 20 participants, half matched for age and education, all males who underwent audiometric assessment and WPPT. Results:Comparing the performance in TFP between the groups was found statistically significant for the group of musicians in both ears, (p = 0.003) for the right ear (RE) and (p = 0.002) for the left ear (OE). The results of the PPT were correlated with the average frequencies, three-tone average and high frequencies mean obtaining a statistically significant only for OD being (p = 0.0047) for low frequencies, (p = 0.011) for average and tritonal (p = 0.02) for the average frequencies. The comparative analysis between the ears, the only group statistically significant variable was the mean of frequencies in the group of musicians (p <0.001). Conclusion:The performance of the group of musicians in the TPF group was superior to non-musicians. Highlights the relevance of the auditory thresholds for low frequencies, acute tritonal average performance of TPF in OD.
