“…In relation to the tendency to an increase in threshold at 3000 Hz, when correlating total time of use, time of daily use, intensity of headphone use and the auditory parameters analyzed with the hearing thresholds at isolated frequencies, the results corroborated classic literature studies, which demonstrated that intense sounds can lead to a temporary or permanent rise in hearing thresholds, primarily at frequencies of 3000 Hz, 4000Hz and 6000 Hz (16,17,18,19,20) . Similar results were found by researchers who reported a difference in sound pressure when young people use devices with earbud and in-ear headphones.…”

Introduction:Hearing loss caused by the improper use of amplifying devices such as smartphones has been growing rapidly. Purpose: Measure and analyze the maximum and equivalent output intensities of supra-aural and intra-aural headphones, compare the adjusted intensities and correlate time and intensity of use, average frequencies of 500 Hz, 1000 Hz and 2000 Hz and the speech recognition threshold. Methods: The sample consisted of 20 subjects from both sexes, between the age of 16 and 27 years. The results were analyzed per ear, totaling 40 ears. The following procedures were adopted: questionnaire application, inspection of the ear canal, tonal and vocal audiometry, impedance testing and assessment of output intensities of supra-aural and intra-aural headphones. Results: Supra-aural headphones have significantly higher equivalent and maximum output intensities compared to their intra-aural counterparts. When adjusted maximum intensities were compared, it was found that intra-aural headphone users used significantly higher equivalent and maximum output intensities than supra-aural headphones users, showing a moderate correlation between time of use and daily use at a frequency of 3000 Hz. Conclusion: During the playing of a song, supra-aural headphones have outputs with greater equivalent and maximum intensities than intra-aural headphones. Intra-aural headphone users use higher equivalent and maximum output intensities than users of supra-aural headphones. Subjects that listen to music often do so for less time during the day, but at greater intensity. RESUMOIntrodução: A perda auditiva ocasionada pelo uso inadequado de aparelhos amplificadores, como smartphones, vem crescendo rapidamente. Objetivo: Mensurar e analisar as intensidades máximas e equivalentes de saída dos fones supra-aurais e intra-aurais, comparar as intensidades equivalentes e máximas ajustadas entre os dois tipos de fones e correlacionar o tempo de uso, a intensidade de uso e a média de 500 Hz, 1000 Hz e 2000 Hz e o limiar de reconhecimento de fala. Métodos: A amostra foi composta por 20 sujeitos de ambos os gêneros, com faixa etária de 16 a 27 anos. As análises dos resultados foram realizadas por orelha, totalizando 40 orelhas. Os procedimentos adotados foram: aplicação de questionário, inspeção do conduto auditivo externo, audiometria tonal e vocal, imitanciometria e avaliação das intensidades de saída dos fones supra-aurais e intra-aurais. Resultados: Os fones supra-aurais possuíam saídas com intensidades equivalentes e máximas significativamente maiores que os intra-aurais. Quando comparadas as intensidades máximas ajustadas, constatou-se que os usuários de fones intra-aurais utilizaram saídas com intensidades equivalentes e máximas significativamente maiores que os usuários de fones supraaurais, observando-se uma correlação de média força entre o tempo de uso e o uso diário, na frequência isolada de 3000 Hz. Conclusão: Os fones supra-aurais possuem saídas com intensidades equivalentes e máximas maiores que os fones intra-aurais, na execuçã...

“…Since personal music players are portable devices, they are convenient for daily use (12) , and since music is considered a pleasant sound, it is regarded as unable of causing damage to the individual (20) . However, the habit of listening to high--intensity music for long durations (1) jeopardizes the hearing health and may cause irreversible hearing damage.…”

Purpose: To verify the habits and attitudes of school-age youths regarding the use of personal music players, and assess their knowledge level about the harmful effects to the hearing of exposure to amplified music before and after an educational lecture. Methods: A total of 58 elementary and middle school students aged 10 to 17 years participated in the study. We presented an educational lecture using an expository dialogue format with audiovisual resources. To evaluate the students, we applied two online questionnaires before and 15 days after the lecture. Descriptive analysis was also performed. Results: Most students reported using personal music players with earphones above the mean intensity of the equipment and for fewer than 3 hours a day. The most frequent complaint was tinnitus. After the educational lecture, there were differences in knowledge about the concept of hearing loss and the fact that high-intensity music in moments of leisure may cause hearing loss. There was also a difference in the intensity used to listen to music with earphones, which decreased. Conclusion: Most students had prior knowledge of the harmful effect of amplified music on hearing and even then, some indicated inadequate habits. The educational lecture showed significant changes in only some of the aspects investigated, reflecting a need to structure continuous actions towards hearing loss prevention in this population. The inclusion of the school and the family in educational actions and the continuity of these actions are fundamental to effective changes in habits and attitudes among children and adolescents.Keywords: Hearing loss, Noise-induced; Child; Adolescent; Health education; Student health services RESUMO Objetivo: Verificar os hábitos e atitudes de jovens em idade escolar com relação ao uso de estéreos pessoais e avaliar o nível de conhecimento sobre os efeitos nocivos da exposição à música amplificada na audição, antes e após uma palestra educativa. Métodos: Participaram 58 estudantes do ensino fundamental e médio, entre 10 e 17 anos de idade. Foi realizada palestra educativa, mediante aula expositiva dialogada, utilizando recursos audiovisuais. Para avaliação foram aplicados dois questionários no formato online, antes e após 15 dias da palestra. Realizou-se, também, análise descritiva. Resultados: A maioria dos escolares relatou fazer uso de estéreos pessoais com fone de ouvido, acima da intensidade média do equipamento e por período inferior a três horas diárias. A queixa mais frequente foi o zumbido. Após a palestra educativa, houve diferença no conhecimento sobre o conceito de perda auditiva e de que música em intensidade elevada, em momentos de lazer, pode causar perda auditiva. Também houve diferença na intensidade utilizada para ouvir música com fone de ouvido, que foi reduzida. Conclusão: Grande parte dos escolares possuía conhecimento prévio a respeito dos prejuízos da música amplificada, para a audição e, ainda assim, alguns referiram há-bitos inadequados. A palestra educativa revelou mudanças si...

“…In one study 13 with 30 subjects and aiming to investigate whether there is damage and the extent of damage due to MP3 players, it was found that people exposed to loud noise show significant reduction in the amplitude of otoacoustic emissions, indicating temporary alterations to cells for the cochlea -damage which may become permanent if the exposure is continuous.…”

“…This technique, which works in function of the volume versus the amount of time used, employs audible beeps at frequencies that can be heard over the music. The user hears the beep, which hinders the appreciation of music and after a reduction in volume, the whistle stops 13 . Among the problems caused by the misuse of headsets are tinnitus, dizziness, difficulty understanding speech, and decreased ability to hear.…”

Objectives:To analyze the habits and behavior of adolescents exposed to amplified music with headphones and its implications on their hearing health. Methods: One hundred thirty-one high school students, aged 15 to 18 years were given a questionnaire containing closed questions regarding their habits and behavior related to personal stereos use. It is a descriptive cross-sectional study and used the Chi-square test. Results: It was shown that 79% of young people make use of portable music devices, 61.83% have a habit of using them often, 34.35% have long periods of exposure, and 37.40% use them at high volume. In terms of symptoms, present were: difficulty concentrating 63.36%; the need to ask people to repeat what was said 64.12%; the need to increase the TV volume 43.51%; tinnitus 38.93%, excitability 38.93%; and 36.64% of teens say they are somewhat worried about losing their hearing through the use of personal stereos. For the preventive aspects, 90.84% believe that noise is part of society, 80.92% find it important to reduce noise pollution, 51.91% would like to know the influence of the noise/pollution, but 74.81% would not like to participate in projects with questions about hearing health. Conclusion: The youths in this study are making indiscriminate use of personal stereos with headphones, within a population at risk for hearing loss considering its habits. Hearing Health Promotion Programs are recommended for this population.
