How to choose good car noise Materials
Xiao Lu just acquired personal vehicles, have not satisfied the past couple of days, problems arrive, and relish calm, he can not stand the traffic is a outcome of "shock, motor running, the breeze and disturbance developed by vehicles friction", but under the He went into the vehicle adornment line, believe through the setting up of insulation to eliminate "the agony in my heart."
A car's designer decorated Xiao told reporters traveling in the vehicle, the driver's attention is very focused, if the vehicle noise at this time larger, it will affect his mood, a long time the brain caused by fatigue easily, it is because of this, and now the installation of insulation to the car more and more people take this kind of work the streets of the converted stores are more and more.
Xiao said that according to different sources of noise, car noise can be divided into many categories: car parts in the internal structure of the body resulting from noise, vehicle and automotive friction stroke of wind, tire and road surface friction noise and car engines have the engine running and the noise caused by external environmental noise.
The internal structure of components for the automotive noise, through the installation of metal plates on the body damping material, so that the whole body more robust, thus reducing the body's resonance frequency, so as to achieve the purpose of noise reduction. The other noise is generated mainly by sound-absorbing sound-absorbing material and sealing the door to solve. Acoustic quality of some products can effectively absorb sound energy and consumption, the door seal glue can effectively alleviate the vibration caused by the body side of the door seal and door frame metal edge gap problem of displacement in order to effectively reduce air noise in the car. The installation of insulation inside the well, can greatly enhance the car's quiet and comfort. However, attention is necessary, installing insulation should not change the structure of the body.
Xiao said that the setting up of insulation components to the vehicle, the cost distinction on a large, widespread at round 1,000 yuan, 5,000 yuan at the high-end around. A allotment of cash in alignment to follow earnings, some adornment shops will be bewildered as genuine ones wantonly deceive buyers, for example some proprietors assertion that they are trading brand-name goods, in detail, are commonplace components, the brand-name tag affixed.
Some shops are also clearly the effect of noise in general and even the materials are not good, he said, not what the voices are high-quality materials can be separated, in order to deal with such as engines and exhaust pipes have a low-frequency noise, it should be the use of lead metal with acoustic foam aluminum or composite materials of polyester PU and metal plate from the noise composite materials, and some of the shop in order to reduce costs is to use sheep felt, sheep blankets on the high-frequency noise must have the effect of noise, but no use on low-frequency noise. Weeding the face of the market, consumers must be paying close, careful selection of decorative lines, and seek advice from many experts, so as to avoid deception.
Xiao said that the setting up of insulation components to the vehicle should furthermore pay vigilance to security, for example to close the body, it is essential to grab the scale, both to double-check a good close body, but furthermore to sustain a balance in order that air force interior the vehicle, if the close initiated by unwarranted hypoxia vehicle, against the identical high.
In general, the use of high-quality insulation elements, the putting in of technical knowledge and sensible, and could be the motor vehicle to lessen racket an midpoint of about 10 db, as a person said, the motor vehicle racket can be lessened by 30个decibels, it is not credible. - 2361
