摘要
探讨了国内外２０种护耳器对石油钻井噪声的防护效果。首先在隔声室内模拟石油钻井工人接触的噪声环境，声级达１０３ｄＢ（Ａ）。采用护耳器主观测量方法对每种护耳器进行噪声防护效果测量，并筛选出噪声防护效果明显的几种护耳器。
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.
