Xiao Lu just paid for confidential motor vehicles, have not delighted the past small number days, difficulties draw close, and savour silent, he can not stand the traffic is a effect of “shock, motor running, the airstream and racket engendered by vehicles friction”, but under the He moved into the motor vehicle embellishment line, consider through the putting in of insulation to get clear of “the hurt 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 as asserted by distinct causes of disturbance, vehicle disturbance can be split up into numerous categories: vehicle components in the interior structure of the body producing from disturbance, vehicle and automotive friction stroke of breeze, exhaust and street exterior friction disturbance and vehicle motors have the motor running and the disturbance initiated by external ecological noise.
The inside structure of elements for the automotive racket, through the putting in of metallic plates on the body damping material, in order that the total body more robust, hence lessening the body’s resonance frequency, so as to realise the intent of racket reduction. The other racket is engendered chiefly by sound-absorbing sound-absorbing material and fastening the entrance to solve. Acoustic worth of some yield can effectually imbibe sound vitality and use, the entrance fasten glue can effectually alleviate the vibration produced by the body boundary of the entrance fasten and entrance perimeter metallic for instance gap obstacle of displacement in rank to effectually lessen air racket in the car. The putting in of insulation indoors the well, can highly enhance the car’s silent and comfort. However, alertness is needed, fitting 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 installation of insulation materials to the car should also pay attention to security, such as to seal the body, it is necessary to grasp the scale, both to ensure a good seal body, but also to maintain a balance so that air pressure inside the vehicle, if the seal caused by excessive hypoxia car, against the same high.
In general, the use of high-quality insulation components, the setting up of expertise and reasonable, and could be the vehicle to decrease disturbance an mean of about 10 db, as somebody said, the vehicle disturbance can be decreased by 30个decibels, it is not credible.
