Abstract: This paper mainly elaborates on the analysis and summary of the distribution of employees with abnormal hearing test results in occupational health examinations based on the noise measurement results from regular occupational hazard detections conducted over the past three years at 16 units within a certain oilfield. Starting with the noise measurement results, field research was conducted on units with a large number of pump-type equipment, high equipment noise levels, and a significant number of pump rooms where noise exceeded 90dB(A). By combining detection data with field investigations, research conclusions were drawn and protective suggestions were proposed to improve the working conditions of noisy operations and to protect the health of workers.

Key words: occupational hazards, noise, protection suggestions
