Great solutions to sound insulation problems! Real shots of Chongqing Yijie Nissan X-Trail four-door soundproofing operation!

Why do we need to insulate cars? That’s because the impact of noise generated by driving cars on us has to attract our attention. A series of problems such as neurasthenia, hearing loss, distraction, etc. are all inseparable from the interference of noise. Car sound insulation is no longer as simple as we think. Substances such as sound insulation damping panels and sound-absorbing cotton among sound insulation materials can greatly absorb or even isolate the noise generated by car panels. Having a good body will help you feel good. Refreshing air, smooth work, and harmonious family, I believe this is what everyone expects. Daneng Sound Insulation has been a leader in the automotive sound insulation industry for more than ten years. Today we are going to talk about Daneng Sound Insulation!
First of all, we need to understand the effect of Daneng sound insulation:
Noise reduction: road noise is almost reduced by half, engine noise becomes deep and powerful, the original buzz disappears a lot, and the sound becomes cleaner. There is a lot less noise, and the peak noise peak at high speed is reduced to decibels.
, Sheet metal reinforcement: The body steel plate becomes as solid as an armored car, which is completely different from the parts that have not been done before. When closing the door, the sound is as thick as that of a luxury car. When passing a hurdle, the body becomes more compact and no longer loose. It feels completely like a new car!
Block heat: Block the conduction of sunlight, engine, and exhaust pipe heat to the cab, completely saying goodbye to the steamer-like cabin in summer. The interior of the car will cool down more quickly, and the energy consumption of the air conditioner will be greatly reduced, saving your fuel expenses!
. Car body maintenance: Prevent the corrosion of the body steel plate, enhance the chassis' ability to resist sand and stone impact and corrosion and rust, and solve the problem of premature aging and fading of the hood paint surface caused by high temperature baking in the engine compartment.
. Reduce vibration: The annoying vibrations of the steering wheel, floor, and gear lever are effectively suppressed. The driver is placed in a private personal space, which not only improves the driving comfort, but also prolongs the use of interior components. service life.
Reason for upgrade: The car door has been completely transformed into a solid and sealed box. The volume of the speaker has increased significantly, the layering of the music has become clearer, the low frequency has become more powerful, and the overall music has become much more delicate and vivid, like a mobile phone. concert hall.
Chassis anti-rust: Form a solid elastic protective layer on vehicle chassis, wheels, mailboxes, car lower panels, trunks and other exposed parts to prevent the impact of flying stones and gravel and the sound of tire friction during driving. Being blocked, moisture, acid rain, and salt will no longer cause corrosion to the car chassis, ensuring that it will not rust and wear for years, greatly improving driving safety and car value.
Car body sealing: Every car has almost more than a dozen completely unnecessary holes. These holes transmit a lot of noise, dust, and heat. These holes and gaps can be completely sealed to improve the overall sealing of the cab. , effectively reduce car noise, save air conditioning energy consumption, and improve the air quality in the car.
Solutions 2 and 3 to Daneng’s sound insulation problems:
1: How is Daneng’s sound insulation performance?
Daneng Top Sound Insulation King is a patented product. It is a lightweight, elastic butyl shock-absorbing composite material covered with an aluminum film. This product bonds easily to sheet metal or other rigid substrates. The most suitable temperature range of the material is -°C to +°C, the temperature it can withstand is between -°C and +°C, and its anti-aging ability is extremely strong.
2: What are the acoustic properties of Daneng Sound Insulation?
The sound loss factor is a measure of the material's ability to attenuate solid-transmitted sound. From this factor you can see how much vibration energy is converted into heat energy (as opposed to sound energy). If a structure includes multiple layers of damping material, a combination factor b is required. The theoretical maximum sound loss factor is approximately (without vibration). The sound loss factor of a metal plate with no damping properties of thickness , is approximately . When used with the panel, Yijie's top sound insulation king can achieve a sound loss factor of up to . (at +℃). The sound insulation performance of the structure can be further improved by using multiple layers of top-grade sound insulation film.
Three: Will Daneng’s sound insulation construction have any impact on the original car?
This issue is also a common concern among car owners. In fact, the car sound insulation project does not require changes to the body structure and various wiring, oil circuits and power systems. Moreover, during the disassembly process, Yijie's car sound insulation and noise reduction center will also prepare some fragile plastic buckles for timely replacement. Sound insulation construction must be carried out in a sealed, bright, and clean workshop by installation technicians who have undergone strict professional training. During the construction process, as long as the process is strictly followed, the car body and interior parts will not be damaged, so everyone must choose a professional car sound insulation and noise reduction mechanism for construction.
Four: What is the sound insulation effect of Daneng?
The effect of sound insulation varies according to different vehicle conditions. Through correct installation, after the entire vehicle is constructed, the noise inside the vehicle can be reduced by about 3 decibels under the premise that the external noise is the same. If a more detailed top-level installation solution is adopted, the effect can be even better. In addition, Yijie sound insulation project can also improve the audio listening environment in the car, especially to meet the needs of professional car audio enthusiasts.
