| Abstract |
Results of comparative studies on the firing technique (direct or hammer-actuated), the make of gun, the calibre, the power of the explosive charge and the size of the premises, on the noise level. The maximum instantaneous noise level, the duration of the noise impulse and the duration of the initial reflex were recorded by means of an oscillograph. Hearing lesions detected by audiometry in bolt-gun users were correlated with duration of exposure. It was found that hammer-actuated bolt guns are preferable from the occupational health point of view. The 9-mm cartridges were extremely dangerous from the noise point of view and their use should be restricted. Under present conditions, it is necessary to make use of personal protective equipment to prevent noise-induced hearing damage. Efforts should therefore be made to improve the design of bolt guns and achieve greater noise reduction. |
