Low-frequency noise refers to noise with a frequency of less than 20 Hz, usually from vehicles, industrial machinery, building construction, etc. Due to the great impact of low-frequency noise on the human body, it is very important to control low-frequency noise. Here are a few common low-frequency noise mitigation measures put together by industrial noise reduction companies.
1.Noise source control: The primary task of low-frequency noise control is to reduce or eliminate noise sources. For vehicles, measures such as reducing vehicle speed and using vibration damping devices can be taken to reduce engine and wheel noise. For industrial machinery, equipment maintenance and adjustment can be carried out to reduce the generation of mechanical vibration and noise. For building construction, noise reduction equipment and sound insulation materials can be installed to reduce construction noise.
2.Sound insulation: Sound insulation is an effective way to reduce propagated noise. For low-frequency noise, measures such as sealing doors and windows, soundproof walls, and soundproof panels can be used to reduce the spread of noise. The selection and use of soundproofing materials is also crucial, for example, the use of sound-absorbing materials and soundproofing membranes can effectively reduce the transmission of low-frequency noise.
3.Shock absorption measures: Low-frequency noise is often accompanied by mechanical vibrations, and shock absorption measures can reduce vibration conduction and noise generation. For example, measures such as shock absorbers, shock absorber plates, etc., can be used in building construction to reduce vibration and noise. In vehicles and industrial machinery, vibration damping devices and vibration isolation devices can be used to reduce the conduction of vibration and noise.
4.Space planning and layout: Proper space planning and layout can reduce the propagation and impact of low-frequency noise. For example, in urban planning, noise sources can be separated from sensitive areas such as residential, educational, and medical areas to reduce the direct impact of noise. In architectural design, rooms and functional areas can be arranged rationally, and noise transmission can be reduced by changing the layout and spatial structure.
5.Education and awareness-raising: Low-frequency noise control requires not only technical means, but also extensive education, publicity and awareness-raising. Through publicity and education, the public's awareness and understanding of low-frequency noise can be enhanced, and the attention and willingness to control noise pollution can be improved. At the same time, it can also remind and guide people to take appropriate behaviors to reduce the generation and spread of noise.
To sum up, the control of low-frequency noise needs to consider many aspects. By taking reasonable and effective measures, we can effectively reduce the impact of low-frequency noise on human health and living environment, and improve the quality of life and environmental comfort.
