The wheel arc can be said to be the main way for tire noise to invade the interior of the cabin, and the front wheel is close to the engine, and the noise is more obvious, so in order to cut off the conduction path of tire noise, Shantou Elvis modification technicians carried out five-layer sound insulation treatment on the front wheel arc and fender plate to reduce sheet metal resonance, absorb and filter medium and high frequency noise, and minimize tire noise.
The original wheel arc and fender plate do not have any sound insulation measures
The 5-layer sound insulation of wheel arc and fender board can effectively cut off the transmission route of tire noise
The door panel is mainly wind noise intrusion is more serious, the modifier uses great white shark 2% to paste the sheet metal inside and outside the door panel, its high density, hardness, thick thickness, can effectively control the resonance of the iron sheet wind noise and vibration noise barrier in the outside, the door panel sealed into a soundproof box, sound insulation effect is better, while providing a good sound environment for the sound field speaker, improve the sound quality. In order to make the sound insulation effect more ideal, the modification technician also used sound-absorbing cotton to further sound insulation treatment on the door panel cover, which can absorb all kinds of noise at the door panel and block the incoming external noise.
The inner layer of the door panel is treated with shock absorption, and the decorative cover is treated with sound absorption
After solving the noise problem, the original car audio began to be upgraded, the front sound field chose Moray Hai Bili two-way frequency, which integrates a number of Moray patented innovative technologies, with excellent performance, vocal performance is round and natural, smooth and full voice, real sense of scene, the singer’s lips and teeth squirming Buddha clearly emerged, such as singing a cappella in your ears.
