| Abstract: | he protective efficiency for noise of twenty types of ear protectors in domestic and aboardfor oil drilling workers were studied in laboratory, we imitated the noise enviroment in which oildrilling workers are in the sound level with 103db(A). To using subjective testing method of earprotector, every ear protector chose 10 testers to wear on and off, then testing the conductionthreshold value amaong 125 - 8KHz frequency range at the same time. The results are shownthat the protection efficiency of 3M ear muffs is the best to oppose against oil drilling noise. Theefficiency of ear protector for noise of TJ, X- 1, 6300 ear plugs and 2453 muffs were satisfied. |
