Abstract

Abstract All over the world, the need for energy is increasing, and the methods of obtaining it are harmful to the environment. Traditional energy resources are rapidly depleting. During the extraction and burning of fossil fuels, many different pollutants enter the environment. One of the renewable forms of energy is wind energy. Wind energy is mainly used to generate electricity in wind farms. Wind turbines are a unique source of noise because they are installed at a high height above the ground, and the noise emitted is fluctuating and manifests itself in a wide frequency range. Noise from wind turbines as low as 32 dB(A) is a strong nervous system irritant for some people, while noise of 40 dB(A) and above causes severe discomfort for many people [1]. Detailed noise modeling was carried out in the considered area, assessing how noise affects individual dwellings, noise in the living environment of residential buildings were modeled. The noise level without background noise sources of the nearest residential environment was determined by modeling at 31.9 dB(A) during the night, while the limit value for the protection of human health according to HN 33:2011 is 45 dB(A).

风力涡轮机运行噪声扩散的建模与评估

摘要全世界对能源的需求与日俱增，而获取能源的方法却对环境有害。传统能源正在迅速枯竭。在开采和燃烧化石燃料的过程中，许多不同的污染物会进入环境。风能是可再生能源之一。风能主要用于风力发电场发电。风力涡轮机是一种独特的噪声源，因为它们安装在离地面很高的地方，发出的噪声是波动的，频率范围很广。低至 32 dB（A）的风力涡轮机噪声会对某些人的神经系统产生强烈刺激，而 40 dB（A）及以上的噪声则会使许多人感到严重不适[1]。在所考虑的区域进行了详细的噪声建模，评估了噪声对个人住宅的影响，并对住宅楼生活环境中的噪声进行了建模。通过建模，确定最近的居住环境在夜间无背景噪声源的噪声级为 31.9 dB(A)，而根据 HN 33:2011 标准，保护人体健康的限值为 45 dB(A)。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
