Life must have Toyota, Toyota also has to Prado, the protagonist of today's article is a Toyota Prado, Prado is a large SUV owned by Toyota, its good off-road function and excellent appearance plan and its super high cost performance for its fierce competition in the off-road vehicle market to win the championship, the model as the name, very domineering.
<h1 class="pgc-h-arrow-right" > the original car audio system analysis</h1>
The Prado is not limited to the details, and the design style is more rugged, which can make it look more wild and uninhibited, but it also causes it to produce more noise when driving. Door panel resonance, low-frequency resonance of the chassis, resonance noise of the tail box, road noise and tire noise, etc. have brought greater trouble to the owner! If you want to reduce the noise in the cabin, the only solution is to do sound insulation treatment for the car.
<h1 class="pgc-h-arrow-right" > Kunming Daosheng Toyota Prado sound insulation modification configuration</h1>
Four doors soundproof: ballet
Chassis sound insulation: ballet + windsor
Main and co-pilot bottom plate sound insulation: small bomb + aviation memory foam + NB2
Hood sound insulation: Ballet + StP military guard hood acoustic cotton
<h1 class= "pgc-h-arrow-right" > four doors of sound insulation</h1>
First of all, a sound insulation of the four door panels, this time we use ballet sound insulation materials, door sound insulation has a good effect on wind noise, coupled with the door side sealing strip, the effect is more ideal. Another point is that the door sound insulation has a good effect on the low frequency effect of the horn.
<h1 class="pgc-h-arrow-right" > Chassis sound insulation</h1>
The main chassis is road noise and tire noise! Using a layer of ballet anti-vibration board, the chassis is laid with a layer of windsor cotton on the basis of shock absorption, which effectively seals the chassis, blocks the intrusion of external noise, and makes the interior of the car quieter.
<h1 class= "pgc-h-arrow-right" > sound insulation under the feet of the main and co-pilots</h1>
The sheet metal resonance under the feet of the main and co-pilots and the vibration noise fed back from the road surface form a low-frequency resonance noise here and are transmitted to the driver's cabin, so the sound insulation treatment of this part is very critical. The main and co-pilot feet are treated with Russian StP bomblets + aviation memory cotton + NB2 sound insulation materials, which can effectively reduce road noise and low-frequency resonance noise.
<h1 class="pgc-h-arrow-right" > Hood sound insulation</h1>
The iron sheet of the car hood part is thin, easy to be affected by engine noise and thermal radiation, causing noise pollution and damage to the hood surface paint, so the modification technician uses ballet + StP military guard hood sound insulation cotton, the hood to do sound insulation treatment, inhibit the transmission of noise,
<h1 class="pgc-h-arrow-right" > summary:</h1>
After doing the sound insulation, the owner couldn't wait to verify the effect, so he drove 5 kilometers on the ordinary city road and the highway. Owner's feeling: the effect is OK when driving on the city streets, and the bumpy road feels obvious, especially over the speed bump; the effect is very significant on the high speed, especially when the speed reaches 80 to 120 kilometers per hour, the "buzzing" sound when driving is reduced very much.
Say goodbye to the "noise" in the car, the Volvo XC60 has a soundproof upgrade
No way? The new toyota Willanda model has to do the whole car sound insulation?
And it wants to be powerful, and it must be practical and not to lose, then the public tanyue will choose this set of trumpets
