当前美国医院内病人接触到的噪声强度已超过美国环境保护局规定的标准。加州大学护士学校、洛杉矶卫生科学中心Topf医师曾作过调查,在11周中对外科楼的每个病房测量2～4张病床,共进行九次测量;在24小时内每间隔2秒记录一下。床头噪声强度为52.63～55.43分贝,而标准允许最大值为45分贝;噪声峰值达68.8～79.3分贝。与此相比,真空吸尘器也仅为70分贝。 At present, the intensity of noise exposure to patients in U.S. hospitals exceeds the standards set by the U.S. Environmental Protection Agency. Dr. Topf from the University of California School of Nursing and the Los Angeles Center for Health Sciences conducted a survey. In the 11th week, 2 to 4 beds were measured on each ward of the surgical building. A total of nine measurements were taken; records were taken every 2 seconds in 24 hours. . Bedside noise intensity is 52.63 ~ 55.43 decibels, while the standard allows the maximum value of 45 decibels; noise peak of 68.8 ~ 79.3 decibels. In comparison, the vacuum cleaner is only 70 decibels.
