Electrification technology does have a significant positive impact on reducing noise pollution. Here are a few key points:
1. Low noise level:
Electric vehicles have lower noise levels compared to traditional internal combustion engine vehicles. Due to the use of electric drive systems in electric vehicles, there is no combustion process of internal combustion engines, which reduces engine noise and exhaust noise. This makes electric vehicles drive in cities with almost no engine noise and exhaust noise, significantly reducing the level of noise pollution in urban environments.
2. Noise control in vehicle design:
Electric vehicle manufacturers have taken a series of measures in the design and manufacturing process to further reduce noise pollution. These measures include using better sound insulation materials to reduce the transmission of road and body noise, optimizing the chassis and wheel suspension system to reduce noise caused by uneven road surfaces and suspension system vibrations, and adopting advanced wind noise control technology to reduce noise levels during driving.
3. Silent driving mode:
Many electric vehicles are equipped with a silent driving mode, allowing drivers to choose this mode when driving at low speeds or parking. Silent driving mode will reduce the power output of electric vehicles, decrease the generation of motor noise and mechanical noise, and further reduce noise pollution.
4. Potential to promote overall reduction of urban noise:
As more and more vehicles turn to electric vehicles, the overall noise level in cities will significantly decrease, creating a more livable urban environment.
5. Synergistic benefits of reducing traffic noise and chemical air pollution:
Research has shown that electric light vehicles and electric buses have a significant impact on traffic noise levels in highly urbanized cities. Electric buses have greater potential in reducing traffic noise, with a maximum reduction of 4.4 dBA during the day in urban core areas.
In summary, electrification technology has played a positive role in reducing urban noise pollution by reducing the noise level during vehicle operation, improving the quality of life of residents, and providing an effective way to create a quieter urban environment.
