Many owners have such feelings, driving, especially when running at high speed, the noise of cars has become the main factor affecting the driving environment. Prolonged exposure to noise will be ringing in the ears, and more than a dream, palpitation and irritability, or directly cause hearing loss or even deafness, which indirectly caused by traffic accidents, vehicle noise is also not uncommon.
En Rui automotive brake caliper, the car noise generally comes from the engine noise, exhaust noise, fan, transmission system, braking system, tire and wind noise modified acquired through most of the noise can be effectively down the.
In do before car noise, you should first check the condition, some noise is caused by the failure of the vehicle itself, such as the tire pressure is not normal, irregular wear, suspension or chassis damage and engine knock. Noise engineering of the system, mainly through the damping, noise reduction, to seal three steps to complete. Door, trunk, car chassis, hood and roof is the most prone to air friction noise, therefore, these places are soundproofed noise reduction processing focus.
As for the noise of the engine, the best under the hood to paste an advanced sound-absorbing foam acoustic material can absorb and consume a large amount of engine noise, but also heat from the engine suppress the hood vibration and barrier to protect the paint surface from heat damage. It is understood by the professional construction technology, does not destroy the original car circuit, does not change the structure of the premise of the original car, the noise engineering noise in the car can be down by 4-8 dB, greatly enhance driving comfort.
Car soundproofing believe many of my friends have heard of, but the practical effect of what is different opinions, but also have to do sound would undermine the argument of automotive interior parts. Although my car to do car soundproofing done, but I have to buy the materials, construction, effect and can not explain the problem.
Many people believe that the car noise is modified before the rise in recent years, you may not think of car noise history dates back to the 1980s of the 20th century, when the United States a group of car audio enthusiasts brought order to be able to better enjoy the car stereo developed for the fun. Shock absorber damping material on the sheet metal of the car and sealed, and improve the defects of the speaker installation environment so as to improve vehicle acoustics. After 30 years of development, a better car soundproofing material, lower prices, while the construction process has become more perfect.
Automotive design has been considered noise problem, but because of cost considerations, many small cars, compact car and Chevrolet will simply do some soundproofing measures, although day-to-day running is no problem, but the pursuit of a comfortable driving experience users, audiophiles, construction noise has become an essential modification.
Construction noise not only quiet and comfortable driving experience, while enhancing the strength of the sheet metal of the vehicle, closed sound fuller, this is reflected in the part of the Japanese car is the most obvious. Vehicles many years the body Songkuang the owners can consider the entire vehicle noise. The engine construction noise reducing heat conduction think the engine hatch, played the role of protective paint. Ceiling soundproof barrier heat conduction to the car in the hot summer.
En Rui car brake caliper learned that vehicle noise is not as we imagine it, the noise can be broadly divided into three categories, low-frequency noise, intermediate frequency noise and high-frequency noise. Noise sources can be divided into the body resonance noise, tire and road surface friction generated tire noise and wind noise three kinds. So to solve the noise problem, it is necessary to start from the. |
