有些文献指出,脑的血液动力学对噪音的作用很敏感,但是噪音引起的听力障碍和脑血液动力学变化之间的相互关系,研究很少。作者研究机器制造业噪音车间工人脑血流图资料和听力障碍的相互关系,观察230名工人,其中听力正常52例,其余发生各种感音性听力障碍,车间噪音98～102分贝,工龄5～27年,工种有锅炉工、锻工和铸工。对照组是30名工作环境无噪音并听力正常的
Some documents indicate that brain hemodynamics is sensitive to noise but there is very little research on the relationship between noise-induced hearing impairment and cerebral hemodynamic changes. The authors studied the relationship between hemogram data and hearing impairment in the noise workshop workers in the machine manufacturing industry, and observed 230 workers, of whom 52 were normal hearing, the rest were all susceptible to hearing loss, the workshop noise was 98 to 102 dB and the working age was 5 ~ 27 years, there are Boiler workers, forging and casting workers. The control group was 30 working environment with no noise and normal hearing
