大型赛事中体育场馆内环境噪音对人群的影响研究

环境噪音对人群健康的影响,除了传统的听力损伤和生理评价标准之外,它对人群的心理影响是不可忽视的.为了补充传统评价模型在心理学方面评价的不足,提出了一种基于模糊分析的评价模型,计算篮球赛体育馆内环境噪音对人群影响的评价指标,以模糊数学的隶属度理论为基础,把环境噪音对人群影响的定性评价转变为定量评价,用来表达环境噪音对人群影响的不确定性;以人群对篮球赛体育场馆内环境噪音的主观感觉和环境噪音的强弱、环境噪音频率以及环境噪音随时间的变化为基础,对评价指标权重进行归一化处理计算评价指标综合矩阵,并采用模糊分析法建立评价模型.通过三部分实验测试,证明所提模型能够准确评价篮球赛体育场馆内环境噪音对人群心理烦躁的影响程度.

Impact of Ambient Noise on Masses in Sports Venues in Large Events

The impact of environmental noise on the health of the population, in addition to the traditional hearing impairment and physiological evaluation criteria, its psychological impact on the crowd can not be ignored. In order to supplement the defi-ciency of traditional evaluation model in psychology evaluation, an evaluation model based on fuzzy analysis is proposed to calcu-late the evaluation index of the impact of environmental noise on the crowd in basketball gymnasium. Based on the theory of mem-bership degree of fuzzy mathematics, The influence of noise on the population is transformed into quantitative evaluation, which is used to express the uncertainty of the impact of environmental noise on the crowd. The subjective feeling and the ambient noise in-tensity, the ambient noise frequency and the environment of the crowd in the basketball stadium Based on the change of noise, the weight of the evaluation index is normalized and the evaluation matrix is calculated and the fuzzy model is used to establish the e-valuation model. Through three parts of the experiment, it is proved that the proposed model can accurately evaluate the influence of environmental noise on the psychological irritability of the people in the basketball stadium.
