Alterações auditivas em trabalhadores de indústrias madeireiras do interior de Rondônia

Abstract

O ruído ocupacional é considerado um risco físico bastante freqüente em quase todos os segmentos industriais e, desse modo, merece atenção especial por parte dos profissionais da saúde e segurança do trabalho. O presente estudo investigou a presença de queixas e alterações audiométricas em trabalhadores de indústrias madeireiras do interior de Rondônia. Participaram do estudo 16 trabalhadores de três indústrias, os quais foram submetidos a uma entrevista sobre a audição, bem como ao exame audiológico por meio da audiometria tonal liminar e da imitanciometria. Todos os participantes eram do gênero masculino, sendo que a maioria apresentava idade inferior a 25 anos e referiu não haver concluído o Ensino Fundamental. Queixas auditivas e uso de protetor auricular foram referidos pela metade da amostra. Os traçados audiométricos revelaram alteração na metade da amostra.

“…In relation to the necessary time exposition for triggering noise-induced hearing loss, the highest number of impairing rates occurs between five and seven years, decreasing loss progression rate until fifteen years when it tends to stabilize as long as exposition conditions and absence of other causative factors are kept 2,4,5 . Noise-induced hearing loss characterized by irreversible cochlear damage, in configuration of high-frequency features one of the most serious, prevalent problems for workers' health.…”
