Abstract

Background : NIHL is irreversible sensorineural hearing loss, affect one or two ears because of exposure to excessive levels of noise in environment. Prevanlence of NIHL not only occur in industrial worker but also in musician. This study is aimed to prove the associatioan between duration of noise exposure with noise induced hearing loss in musician Method : this was a cross-sectional study with consecutive sampling. using musician as a sample. Forty seven musicians fulfilled exclution and inclution criterias during April 2010 to June 2010 measured with pure tone audiometry and noise intensity. Pure tone audiometry exam was conducted by audiologist. Data will be described on table, tested with chi-square, prevalence rasio with SPSS for windows 17 Result : chi-square test between variables using α=0,05, CI95% and power 95%. Chi-square test between duration of noise exposure with noise induced hearing loss X2=4,65 p=0,03 (significant) RP=7,05 (CI95%=0,857-58,164). Conclusion : Prevalence of NIHL increase after five years exposed to excessive levels of noise Keyword : noise-induced hearing loss, musician, duration of noise exposure
