Automobile noise and its harm

The noise on the bus will not only affect people's physical and mental health, but also affect the driver's mood. People often say that music can relieve the pressure of work and life, prevent various chronic diseases and so on. On the other hand, noise not only causes great interference to people's normal life and work, but also affects people's conversation and thinking, causing irritability and unresponsiveness. It may even affect the increase of cancer risk. Driving is noisy, distracting and prone to accidents. More seriously, noise will damage people's hearing and health. Let's watch the car noise and its harm with the car editor of this station.

Automobile noise and its harm. & the main cause of car noise

engine noise

Noise and vibration generated by gasoline combustion in the engine cylinder are transmitted to the cab through the engine cover and front fender. If the engine is badly worn, the noise decibel will increase accordingly.

Solution: By sticking sound insulation cotton with reflective layer in the range hood, the dual effects of heat preservation and sound insulation can be achieved. In addition, Mohji SMK graphene lubricating oil additive can be used to effectively repair the friction marks on the surface of automobile engines, double lubrication, reduce noise and improve automobile power.

Fetal noise

Tire noise is mostly caused by air flow in tire tread gap and air disturbance around tire. Secondly, the tire vibration noise caused by the vibration of the carcass and tread is also a very important factor. Of course, tire noise and road conditions cannot escape.

Solution: The tire and fender liner can be removed, and sound insulation materials can be attached to the four doors, the side position of the doors, the chassis, the position above the wheel arc and the four fenders, and then the soft materials and silent tires with special tread patterns can be replaced, so that the tire noise will be significantly reduced.

Wind noise

Noise is the sound produced by the friction between the air and the gaps and corners of the car during driving. The faster the driving speed, the clearer it is, which is closely related to the wind resistance coefficient in automobile design.

Solution: Wind resistance coefficient is a fixed design when the car leaves the factory, and it can only be compensated by adding a layer of sound insulation cotton on four doors. If the door gap is quite large, in addition, it is necessary to use the automobile sealing strip to effectively block the wind noise.

Automobile noise and its harm. & ampMdash Vehicle Noise Control

It is not easy to keep the car quiet. Cars need sound insulation in many places:

1, engine noise at first.

The partition between the engine compartment and the cockpit needs sound insulation and fire prevention, and some engine hoods will be equipped with sound insulation cotton, which is a common sound insulation means. Most cars above 15W will basically put the soundproof cotton in a suitable position, but it does not necessarily rule out that some rather dark manufacturers will cut corners and save some money.

2. Automobile sealing performance

Automobile sealing strip has the function of filling all kinds of gaps between different parts of the car body, and has the functions of shock absorption, waterproof, dustproof, sound insulation and decoration. It can not only improve the comfort of driving experience, but also ensure the body. Mainly used for door leaves, door frames, front and rear windshields, engine covers and trunk covers. If the sealing strip becomes hard, deteriorated or damaged during the driving of the car, the friction between air and the gaps and corners of the car will produce sound. If the sealing is poor, driving in the middle of the night will make this noise, which is really scary.

3. Tire noise

Most of them are composed of three parts: one is the air flow in the tire tread gap and the air noise caused by the air disturbance around the tire; Second, the tire vibration noise is caused by the vibration of the tire carcass and tread, especially the hard material of the tire, which is especially easy for the small partners to feel the road noise; The third is the road noise caused by uneven road surface. If you don't want the tires to be so noisy, silent tires are a good choice.

Automobile noise and its harm. Harm of automobile noise

Automobile noise will not only increase the fatigue of drivers and passengers, but also affect the driving safety of automobiles. On the other hand, noise also has a serious adverse effect on the digestive system and cardiovascular system, causing indigestion, loss of appetite, nausea and vomiting, which further affects the increase of the incidence of gastric diseases and gastric ulcers, making the incidence of hypertension, arteriosclerosis and coronary heart disease significantly higher than the normal level. Noise can also have a bad effect on the visual organs.

When the car noise comes out, we need to take measures to remedy it year by year. I think the degree of noise interference is a very subjective thing. If the friends feel completely affordable, there is no need to make a hullabaloo about. Of course, if you feel really uncomfortable, you can do four-door sound insulation or vehicle sound insulation if you can, but the price will be slightly higher. The above is the information about automobile noise and its harm shared by Bian Xiao Automobile.
