噪声暴露对认知功能影响的研究

Study on the impact of noise exposure on cognitive function

噪声是我们日常生活中最常见的环境有害危险因素之一,长期暴露于噪声环境中不仅有可能造成听力损失,更为严重的是,它还可能对认知功能造成负面影响。噪声暴露对认知功能的影响涉及多个方面,包括注意力、记忆力、学习工作能力下降等。噪声还会引起机体的应激反应,导致应激激素水平升高,因而可能对大脑结构和功能产生不利影响。此外,噪声暴露还可能导致海马体损害,海马体是大脑中负责记忆和学习的重要区域,其受损会直接影响认知功能。噪声暴露还会引发氧化应激和炎症反应,这些生物过程进一步损害大脑细胞,导致认知功能的下降。

Noise,as one of the most common harmful environmental factors in our daily lives,can lead to hearing loss with prolonged exposure.More seriously,it can negatively affect cognitive function.The impact of noise exposure on cognitive abilities involves several aspects,including but not limited to reduced attention,memory,and learning and working capacity.Noise can trigger stress responses in the body,leading to elevated levels of stress hormones,which may adversely affect brain structure and function.Additionally,noise exposure may cause damage to the hippocampus,an important area of the brain responsible for memory and learning,and its damage can directly impair cognitive function.Noise exposure also induces oxidative stress and inflammatory responses,which can further damage brain cells,leading to a decline in cognitive abilities.
