高原作业环境对听力的影响

Influence of plateau working environment on hearing

摘要:

高原环境具有低温、低氧的特点，随着我国西部大开发战略的不断深入，许多工作人员需要从低海拔区域快速进入高海拔区域，此类人群，极易因低温、低氧而导致人体生理机能的改变，诱发心、脑、肾等多器官功能的损伤。耳蜗及听觉中枢对缺氧极为敏感，缺氧可导致耳蜗微循环障碍进而导致听力下降。听力受损则会导致作业能力下降，所以高原作业环境对听力的影响是我们不得不关注的一个问题，本文通过文献复习的方式对这一问题进行初步论述。

Abstract:

The plateau environment is characterized by low temperature and low oxygen. With the deepening of China's Western Region Development Strategy, many workers need to quickly move from low-altitude areas to high-altitude areas. For these people, multiple organs function is reduced by physiological changes because of low temperature and hypoxia, which induce the damage of multi-organ functions such as heart, brain and kidneys. And the cochlea and auditory center are extremely sensitive to hypoxia, which can lead to cochlear microcirculation disorders and hearing loss. And hearing loss will lead to the decline of working ability. Therefore, we have to pay attention to the impact of altitude working environment on hearing. This paper preliminarily discusses this issue through literature review.
