Estéreos pessoais: hábitos auditivos e avaliação audiológica

Abstract

OBJETIVO: Caracterizar os hábitos auditivos e relacioná-los aos achados audiológicos de adultos sem queixas auditivas, usuários de estéreos pessoais. MÉTODOS: Foram avaliados 85 indivíduos, com idades entre 18 e 34 anos, com audição normal, sem exposição a ruído ocupacional. Todos responderam a um questionário de hábitos auditivos, disponibilizado na Internet e foram convocados para a avaliação audiológica: Audiometria Altas Frequências, Emissões Otoacústicas Evocadas por Estímulo Transiente (EOAT) e Emissões Otoacústicas Evocadas por Produto de Distorção (EOAPD). RESULTADOS: Os participantes do estudo ficam expostos à música por mais de duas horas diárias, há mais de quatro anos, normalmente em meios de transporte. Observou-se um entalhe em 6 kHz no delineamento da configuração audiométrica a partir das médias dos limiares auditivos de via aérea, característico de PAIR. Quanto maior o tempo (em anos) de exposição ao som, maior a chance de ausência de EOAT e incidência de zumbido. A maioria se preocupa com a saúde auditiva e acredita que os maus hábitos podem causar danos à audição. CONCLUSÃO: Embora os indivíduos não tenham apresentado queixas auditivas, aspectos relacionados à exposição ao ruído foram evidenciados, tais como zumbido, estresse e relatos de dificuldade crescente de inteligibilidade de fala com o aumento do ruído ambiental.

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

“…Data on concern about hearing health proved to be in line with the findings of a study 38 conducted in the United States (USA), yet the data disagreed with another study 1 conducted in Brazil, where most care about hearing health and believe that bad habits can damage hearing.…”

“…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 .…”

Hábitos e queixas auditivas de adolescentes usuários de estéreos pessoais

“…This abusive use with high duration, intensity and/or frequency of exposure to music may lead to auditory function disorders [3][4][5][6] and it may cause severe consequences to life quality 7 . The occurrence of auditory symptoms such as hypoacusis, ear fullness or dizziness and tinnitus after using personal stereos may suggest higher risks to young people's hearing 5,6,8 . It indicates a relationship among these symptoms and the habit of using personal stereos 5 .…”

“…It is important to highlight that tinnitus may cause concentration, sleep and learning interference, becoming an important symptom to be investigated, because it is common in this population 3 . According to a recent study, as longer is the time of headsets use, higher is the tinnitus occurrence 6 . Besides, another study observed that people with tinnitus may present alteration of medial olivocochlear tract function, observed through lower otoacoustic emissions suppression 14 .…”
