Value-added exports by HS code

The Value-added exports by HS codeengine is very noisy (the engine is very noisy, and soundproofing materials need to be installed!) When you step on the accelerator and feel the strong sense of acceleration, will you feel restless because of the noise of the engine? Many people will think that it is normal for the engine to be loud, and it can also stimulate the passion of car sports. However, in fact, the excessive noise of the engine will not only greatly reduce your driving experience, but also seriously affect your health. Therefore, for vehicles with excessive engine noise, we must take action to install soundproofing materials to prevent them from making too much noise. In the process of driving a car, engine noise is inevitable. However, car manufacturers have certain requirements. In the process of vehicle development, it is necessary to take into account the problem of engine noise.Therefore, in the design, some manufacturers have adopted some soundproofing measures. However, in order to pursue higher engine performance, other car manufacturers often reduce the sound insulation of the engine, resulting in greater noise in the vehicle. If the engine noise is too loud, it will pose a threat to the driver's attention and reaction speed, which in turn will affect driving safety. Scientific research shows that when the sound of the car engine exceeds 85 decibels, it is easy to cause the driver's hearing impairment. For long-term drivers, it may cause insomnia and affect the quality of sleep, thus causing greater harm to health. How to solve the problem of excessive engine noise? It is mainly handled by installing soundproofing materials. The use of soundproofing materials can improve the noise control effect of the car, thus improving the driving comfort and driver's safety.It can effectively reduce engine noise and improve the muting effect of the carriage. There are many ways to install soundproof materials. You can choose to install soundproof material boards, soundproof felts, soundproof stickers, etc. At the same time, corresponding materials should be used for the noise of different parts. For example, for the engine compartment, you can choose to install soundproof felt and soundproof panels to reduce the spread of cabin noise. For car doors, floors and other parts, soundproof stickers can be used to treat them. Not only that, the maintenance of the vehicle can also reduce the engine noise to a certain extent. Regular maintenance can prevent and solve many mechanical and electrical problems and reduce the generation of noise. At the same time, doing a good job of oil replacement and mechanical parts can also effectively reduce the generation of engine noise. In a word, for vehicles with loud engine noise, we should take measures to reduce excessive noise.Installing soundproofing materials is an effective way to improve driving comfort and improve the driver's health. In addition, regular maintenance of vehicles can also reduce engine noise to a certain extent.
