在生产实践中,噪声与振动往往同时存在,研究与探讨噪声与振动联合作用下,对机体某些生理机能的影响,具有现实的意义。为此,我们在实验室对接触噪声与振动的大白鼠进行实验,观察了在噪声与振动的联合作用下,机体生理机能的某些改变。一、实验条件与内容噪声振动源为一振动台提供。振动参数:我们选定的振动频率为30赫兹,振动加速度为3～5米/秒~2。噪声级即振动台起动后的噪声为87.5～90分贝(A)。
In production practice, noise and vibration often exist at the same time. It is of practical significance to study and explore the effect of noise and vibration on some physiological functions of the body. To this end, we experiment with rats exposed to noise and vibration in the laboratory to observe some of the changes in the physiological function of the body under the combined effects of noise and vibration. First, the experimental conditions and content Noise vibration source for a shaking table. Vibration parameters: We selected the vibration frequency of 30 Hz, vibration acceleration of 3 ~ 5 m / s ~ 2. The noise level is 87.5 ~ 90 decibels (A) after starting the shaker.
