Measures to control noise pollution

With the development of society and the improvement of people's living standards, noise pollution has become more and more serious. For example, the noise from house decoration, car noise, industrial noise and entertainment noise will affect people's daily life. Solving the problem of noise pollution has also become a top priority in improving the quality of life. How can we effectively solve the noise problem? Let’s talk about how to deal with the noise problem.

Method 1: (1) Where does noise pollution come from? Common noise sources in life can be divided into traffic noise (vibration and honking of large vehicles), construction noise, industrial noise, excessively loud entertainment noise, etc.

(2) The hazards of noise pollution. Noise brings physical and psychological harm to people and damages hearing. Long-term exposure to noise is harmful to the cardiovascular system, causing symptoms such as panic, high blood pressure and fatigue. It affects the nervous system, causing emotions such as impatience, anxiety, tension, irritability, depression, accompanied by symptoms such as headache, upset, and memory loss. It also affects sleep, causing fatigue, decreased work efficiency, slow reaction and other bad behaviors.

(3) Measures and suggestions for the prevention and control of noise pollution. The main measures to reduce environmental noise pollution are to control noise sources, such as prohibiting vehicles from honking their horns in urban areas, construction units adopting closed construction methods, prohibiting construction at night that disturbs residents, reducing noise emissions in entertainment venues, and strictly controlling noise emissions at industrial enterprise boundaries.

Method 2: The number and flow of motor vehicles are the main causes of traffic noise. Theoretically, if the vehicle speed doubles, the noise will increase; if the vehicle flow doubles, the noise will increase. Therefore, strictly and reasonably controlling the number and flow of motor vehicles is an important way to reduce urban traffic noise and actively promote the development of urban public transportation.

Method three: Greening noise reduction: Greening noise reduction mainly uses the absorption and reflection of sound waves by plants to achieve a certain noise reduction effect. It should choose short evergreen shrubs and evergreen trees to achieve three-dimensional greening. As can be seen from the figure below, the effect of noise reduction through greening is not obvious, and it is difficult to achieve noise reduction through greening in my country where land is scarce. However, the widespread use of greening and green belts mainly aims to reduce noise psychologically, beautify the environment, and increase visual and aesthetic effects.
