Noise induced hearing loss has become a serious public health issue that needs attention. This study aimed to determine the prevalence of hearing loss among saw-millers in major plank saw mills in Osogbo, Osun state. It is a cross sectional descriptive study using structured questionnaire and pure tone audiometry. A total of 73 subjects and 72 controls with age range from 16 – 71yrs. Majority (77.1%) of the operators have been operating machine for more than 10yrs. Over 18% (subjects) complained of hearing loss compared with 8.2% (control), (t = 35.476, p = 0.000). Most subjects (71.1%) have no knowledge of hearing/ear protection and only 5.6% of machine operators make use some protective devices. More than 41% (subjects) had hearing loss compared with 16% (controls) (t = 19.881, p < 0.001). There is a need for public enlightenment on the deleterious effect of noise on the populace.
