This study assessed the intensity and likely effects of noise on workers during wheat processing. Noise measurements were taken using HD600 sound level meter. Subjective assessment of the effects of noise was undertaken using semi structured questionnaire. Also audiometric test was conducted on workers using AD229e diagnostic audiometer. The results of the study show that during wheat processing operations, the noise level in the factory ranges between 56.0 dB(A) and100.9 dB(A). Also, only 25.6 % of all the readings was below the specified limit of 85 dB(A). Workers are also observed to have certain forms of physiological and psychological disorders related to noise. The audiometric test results revealed that 33 % of the examined workers have defect in their left or right ear. Based on these results, WHO Class-5 hearing protector is recommended to be worn by workers in the processing sections while room acoustics should be upgraded to absorb some sounds transmitted to offices. © JASEM
