Car soundproofing, Chongqing Daneng Soundproofing Yijie is more professional

Benefits of car sound insulation | Role of sound insulation | Characteristics of sound insulation: , Benefits of sound insulation for car audio - improve the audio quality and reproduce the original taste of music. Let's first understand what unfavorable factors the car structure has on audio installation
How to install speakers The bracket and bottom plate (door) are not rigid enough: When the speakers on the car sound, the sound waves from the speakers will not only be transmitted forward, but also transmitted backward at the same time. When the sound waves transmitted backward impact the bottom plate, the bottom plate will resonate with the speakers. Or vibrating, causing the sound pressure of the speaker to be lost and causing harmonic distortion of the speaker, resulting in deterioration of sound quality.
The box (door) where the speaker is installed is not tight enough, and the phase difference between the sound waves in the forward and backward directions of the mid-woofer is large. Because the wavelength of low-frequency sound waves is longer and its diffraction ability is strong, the directionality of low-frequency sound waves is very weak. Since the door speaker mounting panel is full of holes, the sound waves radiated backward will go around to the front and cancel each other out with the sound waves in the front. This will cause the forward-transmitting acoustic radiation energy to be greatly weakened (ie, acoustic short circuit). As a result, the mid- and low-frequency volume is insufficient.
How can sound insulation make up for the shortcomings of the original car structure?
) Our sound insulation material has a two-layer structure: rubber damping material and outer metal sheet.
When the metal structure vibrates, the damping layer also vibrates, but is constrained by the outer metal sheet, thereby attenuating the vibration energy transmitted along the structure, suppressing the vibration of the metal structure, and weakening the resonance and trembling of the base plate. The result is a speaker that plays purer, more natural music.
) Car doors can be easily sealed with large sound insulation materials. Because the sound insulation material can penetrate into the fine gaps of the car body steel plate, and can seal and seal the holes in the iron plate, thereby turning the car door into a solid and sealed box, it can effectively improve the sound quality of the car audio. Bring unexpected effects to car owners.
In audio modification and audio upgrade, sound insulation is an essential step, which can make you get twice the result with half the effort. A survey shows that sound insulation can improve the sound effect by more than 3%.
. The benefits of sound insulation for car drivers: Improve ride comfort and reduce safety hazards. Let’s first understand what harm car noise directly causes to people) When the noise is too high, it will make people uncomfortable, tinnitus, or easy to fatigue. Scientific research has found that when people are in an environment with noise greater than decibels, they will develop anxiety and irritability.) When people are in an environment with high decibel noise for a long time, their hearing will decrease, which will affect the abnormal feeling of the car itself. to cause driving safety hazards. According to incomplete statistics, accidents indirectly caused by noise in cars account for 10% of all traffic accidents, which is enough to illustrate the harm caused by noise. What are the benefits of soundproofing your car? ) Isolate the noise outside the car, protect your physical and mental health, care for your family, improve the quality of the car, and enhance the comfort of the ride. ) Absorb and reduce the noise in the cabin caused by vibration, improve ride comfort, eliminate journey fatigue and eliminate noise damage to the human body. Vehicles that have been soundproofed can make the soundproofing effect of low-end models reach the level of mid-range cars. At the same time, the safe driving and stability of the vehicle are increased, and the ride is more comfortable. Let the safety factor be improved.
Yijie Daneng Sound Insulation | Characteristics and functions of sound insulation for the whole vehicle:
, hood paint maintenance project-isolating engine noise and reducing engine resonance noise
The face of the entire vehicle engine The paint surface will age prematurely if it is baked under the high temperature of the engine! Choosing Daneng hood insulation film can not only reduce the baking of the hood by engine heat, keeping the face of your car always bright, but it can also effectively absorb the mechanical noise of the engine and reduce the transmission of engine noise to the inside and outside of the car.
, car floor sound insulation and heat insulation project - engine noise reduction, hot gas emission reduction
The construction of the car floor and internal firewall is to focus on solving engine noise and road noise, and a large amount of low-frequency noise is to solve these two problems. Daneng's unique low-frequency king not only effectively isolates low-frequency noise, but also greatly reduces the heat transfer from the engine exhaust pipe to the car, allowing you to enjoy quiet driving while the car is cooler and more comfortable.
Four-door sound insulation enhancement project-sound effect improvement, door road noise reduction
The four doors are the main source of noise in the car. DaNeng’s double-layer sound insulation treatment for this part will effectively reduce the transmission of noise through the doors. In addition to the large amount of road noise coming in, the sound quality of the speakers installed on the doors can be greatly improved by turning the doors into speakers, making your driving more fun.
. Trunk sound insulation and noise reduction project - super bass reduction, rear tire dryness reduction
The trunk is the main source of noise in the car. The sound insulation treatment of this part will effectively reduce road noise. At the same time, the reinforced trunk will make the car body more secure when driving, and can also greatly improve the sound pressure and sound quality of the subwoofer installed in the trunk. The trunk and door sound insulation together form the basic engineering of Daneng Automobile's sound insulation.
