中文摘要
在产品和环境辐射的噪声特别是中高频噪声得到有效控制的情况下，低频噪声污染备受关注，这在对声环境质量要求较高的工作和居住场所中尤为突出。本项目开展了低频噪声暴露下人体生理效应和心理主观烦恼度的联合研究。研究不同声暴露下受声者在安静状态时脑电、心电等生理指标的变化特征及主观烦恼，重点探索了生理指标变化特征与低频噪声引起的主观烦恼度之间的相互关系，建立了两者之间的数学关系模型。同时，通过低频噪声暴露下的动物实验，观察动物行为学变化、生理指标变化以及脑组织中枢神经细胞形态学变化，就低频噪声对机体生理指标产生影响的病理学依据进行研究。研究成果可为根据机体生理指标的变化估计低频噪声主观烦恼度提供坚实的理论和实验基础，具有较强的学术价值和现实意义，同时也可为我国产品和环境噪声标准制定、低频噪声控制等相关领域的应用研究提供有力支撑。
英文摘要
As the intermediate and high frequency noises radiated by products and environment were controlled effectively, people pay more attention to the low frequency noises, especially in residential areas or workarounds which require highe acoustical environment quality. This project was carried out on the investigations of human physiological effects and subjective annoyances under sound exposure, and studyed on the changing characteristics of physiological indices and subjective annoyance when the testee was sitting down calmly,such as EEG and ECG. The relationship between the variation characteristics of physiological indices and subjective annoyance was focused on and the relational model was established. Meanwhile, animals experiments under low frequency noise exposure were carried out, in order to observe the changes of animal behavior, physiological indices and the morphological changes of nerve centre system cells in their brain tissues and disclose the pathology foundation of the physiological indices variations. The research results can be used to evaluate the subjective annoyance of low frequency noise exposure according to the variations of physiological indices, and provide a significant theory and practice supports for the further application researches,such as low frequency noise control, products and environment noises criterions establishment and other related fields.
