HS code segmentation for industrial chemicals

The HS code segmentation for industrial chemicalssound of the motorcycle engine rattling: behind the "the sound of the motorcycle engine does not stop" has long become a common fact in cities or in areas where the atmosphere of locomotive culture is popular. In particular, the particularly loud "da-da sound" that seems to shatter everything is even more complicated. On the one hand, it represents a free, unrestrained and individual attitude; on the other hand, it will also cause discomfort and troubles for many people.So, what is hidden behind the sound of the motorcycle engine? First of all, we need to know that the sound of the motorcycle engine is mainly caused by the exhaust system. When the engine burns oil and gas, it produces high-temperature and high-pressure gases, which need to be discharged through the exhaust pipe. Inside the exhaust pipe, there is a device called "muller", which will silence noise; however, some motorcycle owners who pursue "lavish" culture will choose to remove the silencer to increase the ventilation performance of the exhaust system, so that the sound of the engine is louder and more shocking. However, this kind of "lavish" behavior has caused a lovely controversy: is it a manifestation of self-showing and the pursuit of freedom, or an irresponsible and disrespectful behavior? For this question, the author believes thatA distinction should be made: in motorcycle professional competitions, gatherings and other places, the sound of motorcycle engines is considered a normal thing. On this occasion, the noise of the motorcycle engine is a kind of competitive sport, representing the challenge and courage of the driver. However, in some public places (such as residential areas, commercial blocks, etc.) or in the dead of night, showing off the sound of the engine becomes an irresponsible act. First of all, the sound of the engine can easily affect the lives of the surrounding residents. Especially in the middle of the night, on a quiet night, the noisy sound of the engine will make it difficult for people who must sleep to fall asleep, or interfere with the growth and learning of children. This kind of unconscious interference will not only increase people's stress, but also easily cause mental illness in the long run. Secondly, the high-decibel sound of the motorcycle engine will also affect your health.According to statistics, in a noisy environment for a long time, auditory organs and nerves will suffer different degrees of damage, even leading to deafness and other diseases. And riding a motorcycle itself also has a large part of the risks and dangers. If you focus too much on the sound of the engine and ignore safety when riding, the probability of accidents will be greatly increased. Considering the above factors, we can think that the behavior of the sound of the motorcycle engine is a manifestation of personality, but it should be within a reasonable range: that is, it is expressed within the scope allowed by the place, time and environment, and to fully consider and respect the rights and interests of others and oneself. In summary, the "clatting sound" of the motorcycle engine is not a simple problem. It may be a channel for a person to choose personality, express himself and get applause, but it may also be an irresponsible, disrespectful and health-conscious behavior.Therefore, while enjoying the motorcycle culture, we should also take responsibility in practice. On the premise of respecting the interests and rights of others, we should minimize the impact of motorcycle sound on the body and mind, and contribute to a good living and social environment.
