Car Noise Sources
1. Engine noise engine noise is generated by normal operation of
the engine, when the seal inside the car is bad, naturally incoming
2. noise, tire tire material is hard, driving, especially in
potholes, pavement, frictionwith the ground, impact noise, and
parts such as fenders, Fender vibrations form aresonance
amplification of incoming vehicles
3. Wind in the car while driving, vehicle collided with air
4. mechanical aging: aging itself loose due to mechanical parts,
running very loudvibration noise can occur.
auto sound insulation project engine noise, vibration, body door
can be resonance, driving and road surface friction, air
resistance, effective elimination and barrier, giving you a quiet
drive space, greatly improve the driving comfort.
Strengthening the Car
covers, doors, reserved spaces, roof, Fender non key site pull the
metal is relatively weak, after installing insulation, solid body,
whenthe collision occurred, increased passive safety.
Optimization of sound effects
sound, especially the installation of the subwooferin the rear
part, can cause the trunk vibration, sound reduction, this is
because there is no proper shock absorbing car structure cannot
afford Mega Bass impact, issued a buzzing sound. After
soundproofing after construction, eliminating bodyresonance of the
metal, but also has good sound-absorbing effect, can sound more
clear, vigorous, surge.
The noise of construction material
Noise mitigation works mainly through the following two ways
1. use the vibration insulation materials to achieve the purpose of
muffler noise. For example: chassis door, luggage after you paste,
such as vibration deadening, itwill reinforce the body structure
and control the role of resonance between bodyand external noise.
This is because the paste after the vibration insulation. Changethe
natural frequency of the body, controlling vehicle noise and
resonance and resonance of the body, thus effectively trap a noise.
2. using sound- absorbing materials to achieve the purpose of
muffler noise. For example the hood in the engine using sound
absorbing materials decreased engine noise. This is because the
sound-absorbing material is an acoustic foam material it horizontal
distribution of open and closed-mouth the mouth, effectively
noiseswhich sound energy is converted to mechanical energy and heat
energy consumed, to achieve the aim of absorbing noise
Sound proof construction considerations
1. Note When removing demolition techniques, not with brute force
and damagethe surface and the paint layer, all of the clips you
want to use a dedicated buttontool.
2. dealing with the attachment should pay attention to the
intensity and directionof force to prevent scratching the paint and
cut the Panel. After using the cleaner,be sure to close the lid to
avoid volatile cleaning agent or knocked to clean bottles.
3. when cutting, stitching can be avoided as far as possible and
4. chassis with the lines and air conditioning vents must not be
5. flooring installation steps to complete after finished ceiling,
avoid soiling or damage the seats and carpets.
6. in a car with air bags work, be sure to pull out the split key,
light skin, prevent the air bag explosion cause vehicle damage
Car makes a noise after construction, vehicle noise can be reduced
by 8-15 DB. When the vehicle is up to 80-120KM/hours, passengers in
the car in conversation and improve ride quality, and enhanced ride
comfort. Original sound without changing the case, you can increase
sound pressure levels. Switch door cannot hear sound, voice thick;
enhance body strength, delaying the aging of body parts.
