厦门市卫生防疫站对63家外资工业企业噪声强度进行调查,结果表明,噪声强度在70~122分贝(A)之间,546个监测点中,符合卫生标准的306个,合格率为56.1%。 噪声强度按行业分,依次为印刷、制鞋、电子、纺织、家具及食品业。63家企业中只有13家企业工业噪声符合卫生标准,合格率为此次调查企业总数的20.6%。噪声类型主要有磨擦、冲击和机械振动引起的噪声,一般声压级较高,频谱范围较宽,中高频噪声占
Xiamen Municipal Health and Epidemic Prevention Station of 63 foreign-invested industrial enterprises to investigate the noise intensity, the results showed that the noise intensity is between 70 ~ 122 decibels (A), 546 monitoring points, in line with the health standards of 306, with a pass rate of 56.1% . Noise intensity by industry, followed by printing, footwear, electronics, textiles, furniture and food industry. Only 13 of the 63 enterprises had industrial noise meeting the hygiene standards, with the passing rate of 20.6% of the total number of enterprises surveyed. The main types of noise are noise caused by friction, impact and mechanical vibration. Generally, the sound pressure level is high, the spectrum is wide, and the high-frequency noise accounts for
