Achados audiológicos em jovens usuários de fones de ouvido

Abstract

Objetivos analisar a relação entre o uso de fones de ouvidos e os comprometimentos auditivos e extra-auditivos provocados pelos tocadores portáteis de música. Métodos a proposta foi coletar dados, por meio de um questionário respondido pelos participantes. Realização dos exames audiométricos: audiometria tonal e vocal; imitânciometria e pesquisa dos reflexos acústicos; emissões otoacústicas transientes e emissões otoacústicas produto de distorção, posteriormente os dados foram comparados entre os indivíduos de um mesmo grupo e os grupos foram comparados entre si (grupo experimental e grupo controle). Para a análise estatística foi utilizado o teste Qui-Quadrado e exato de Fisher. Resultados algumas das variáveis investigadas, tais como o uso de fones de ouvido de 1 a 2 horas diárias, a presença de queixas auditivas e extra-auditivas, exposição a níveis de pressão sonora elevados extra-ocupacional uma vez por semana, ser não fumante, não usar medicamentos controlados e não apresentar zumbido possuíram frequência estatisticamente significante para o grupo experimental. Em relação às queixas auditivas houve diferença estatisticamente significante entre os grupos experimental e controle para sensação de ouvido abafado e sensação de rebaixamento auditivo. Conclusão os sintomas temporários indicam os potenciais efeitos nocivos de ouvir tocadores portáteis de música por uma hora ao dia. Pesquisas ainda são necessárias para avaliar os prejuízos de longo prazo ao sistema auditivo.

Amplified music with headphones and its implications on hearing health in teens

“…Studies have shown in using headphones, a period of two hours is sufficient for subsequent hearing impairment hearing. It was also found that listening to loud music directly into the ear can damage the sensitive hair cells in the inner ear [2][3][4]6,[28][29][30] .…”

“…However, not everyone knows that excessive use of these devices may cause irreversible damage to hearing 1 , in the short or long term 2 . This habit, when frequent, added to the exposure time, the physical characteristics (such as frequency and intensity), and other non-occupational noise at high sound levels, determines the impact on hearing health, and results in a public health problem, which affects most of the world population [1][2][3][4] .…”

Hearing loss induced by music or by high sound pressure levels (HSPLIHL) has similar characteristics to hearing loss caused by occupational exposure to noise, with slow onset, progressive, irreversible, sensorineural, bilateral hearing loss that initially affects high frequencies and then the other frequencies 2 .…”

Such a loss can develop into a major public health and social problem since a growing number of adolescents and adults have symptoms related to exposure, such as distortion, intolerance to loud sounds, dizziness, earache, difficulty understanding or hearing words, tinnitus, and alterations in auditive thresholds 5,6 .…”

“…[1][2][3][4][5] Indeed, noise is a trademark of modern society 6 and people are generally aware of it, but why is so difficult to change their attitude toward this reality?…”
