【摘要】 制钉行业噪声污染十分严重,国内外对于此类噪声的治理尚无成熟的经验和公开发表的资料。本文在对昆明制钉厂的调查研究和制钉车间噪声测定评价的基础上,结合信号处理技术,对噪声的时域特性、频谱特性及噪声源进行分析探讨,并提出了综合治理制钉行业噪声的措施。更多还原

【Abstract】 The noise pollution of naileries is very strong, and there is no efficienry method to control yet. Based on the study of KUNMING Nailery and the evalution of noise to the nail-workshop, and combined with signal processing technique, the time character, spectral character and acoustical mechanism of the noise have been analyzed. Then the idea that control the noise of naileries overall has been offered.更多还原
