As a mid -to -high -end urban SUV model, Kia Lion runs a pure urban SUV bloodline. It abandons the rough shape of the traditional SUV. The overall design maintains a powerful style, and at the same time integrates the design concept of cars. It is a popular urban SUV model. But the shortcomings are too noise, especially when driving at high speeds. In order not to be troubled by the annoying noise, Kia Lion runners came to Xiamen Liangcai Port car audio for sound insulation and noise reduction. After testing, I learned that the noise is mainly from the engine and trunk. So the owner decided to sound insulation on the engine and trunk.
Kia Lion Run Upgrade the Big White Shark sound insulation preparation for construction:
Construction materials and corresponding sites:
Great White Shark Golden Shark -Engine
Great White Shark Silver Shark -Box Barrier
The first is the engine sound insulation. The engine sound insulation is divided into two parts: hood sound insulation and sink sound insulation.
Unload the original car hood thermal insulation pad and found that there is no sound insulation measures:
The first layer of the hood is soundproof, and the high -quality shock absorption board of the large white shark is strengthened to strengthen sheet metal to suppress resonance.
The second layer of sound insulation of the hood, equipped with large white shark engine sound insulation cotton, can not only effectively absorb noise, but also greatly weaken the heat produced by the engine to bake the hood paint surface to prevent the hood paint from accelerating aging.
The sink is the only way to pass the engine noise into the compartment. The purpose of sound insulation in the sink is to block the noise from the cockpit.
Then there are two parts of trunk sound insulation. The trunk sound insulation is divided into two parts: trunk sound insulation and tail cover sound insulation.
The large air cavity of the trunk sheet metal is large and the cavity is very easy to produce strong resonance and is not easy to dissipate. Therefore, the trunk has become one of the main sources of noise.
The first layer of the trunk sounds sound insulation, and the high -quality shock absorption board is affixed to the high -quality shock absorption board:
The trunk second sound isolation, sticking to the large white shark high -quality sound insulation cotton absorption noise:
The first layer of the rear tail lid is sound insulation, and the high -quality shock absorption board is affixed to the large white shark to reduce resonance.
The second layer of the rear tail lid sounds sounds, and the high -quality vibration plate of the Great White Shark is fully reduced.
Finally, the big white shark sound insulation cotton is installed to absorb noise:
Kia Lion Run upgraded the sound insulation of the Great White Shark. After the sound insulation was completed, the car was a lot quiet. When the owner again increased the throttle at a high speed, he could no longer hear the noisy engine noise and the stuffy roar of the trunk.
