ABSTRACT
Noise exposure is one of the most common occupational hazards worldwide. The aim of this study is to investigate the extent of noise exposure and the associated noise effects among abbatoir workers in Benin City, Nigeria. This research employed a cross-sectional design using a sixty (60) well-structured questionnaire and a quantitative measurement of noise levels using a calibrated Smart Sensor Digital Sound Level Meter (Model AS824). The result shows that the mean noise level ranged between 70.3db to 80.3db. Results reveal elevated noise levels within the abattoir, particularly during morning operations with peak levels exceeding recommended occupational exposure limits. The occurrence of hearing difficulty, high blood pressure, stress, sleeplessness, and increased heart rate was reported among the workers. The duration of noise exposure significantly rate (c2 = 3.609, p<0.047) associated with increased heart rate among the respondents.
