What are the benefits of doing four door sound insulation, and the pros and cons of doing four door

Four-door sound insulation can achieve the following effects:

1. Block external environmental noise.

Driving on a road with more cars, whether you are overtaking or being overtaken, you can hear the noise of the other party's car, especially when it is side by side with the bus or truck, the noise is very large, and the noise will be reduced after doing four doors.

2. Improve the sound effect.

In the past, there were many holes in the steel plate of the door, and the steel plate was thin, and the resonance of the steel plate caused the sound distortion when the speaker was turned on. When the resonance of the steel plate inside and outside the door is suppressed and the hole is blocked, then the door forms a box, and everyone knows that the horn can only show good results in the box.

3. Enhance the sense of heaviness of the steel plate.

The anti-vibration pad restricts the bending of the steel plate and prevents it from vibrating, and when it hits the steel plate, it will make a dull sound, and it is no longer a crisp sound.

4. Make the sound of closing the door good.

After sound insulation, each door increases by about 4 kilograms, and the inertia of closing the door is greater than before, and a "bang" sound can be heard at the moment of closing the door.

5. Thermal insulation.

The sound insulation material is a rubber product, which has the function of thermal insulation.

After the sound insulation of the four doors, it can block the external environmental noise, make the closing sound better, enhance the strength of the steel plate, and improve safety. In addition, if it is a double-layer sound insulation and vibration dampening made of four doors, it can also greatly improve the sound effect. But to do sound insulation should pay attention to one point, the current market of materials are mixed, do not be greedy for cheap use of those three no products.

The specific pros and cons of making 4-door sound insulation for cars are as follows.

Four-door sound insulation is to paste a special soundproof blanket in the door trim to reduce the resonance caused by the thinner door sheet metal parts when driving, reduce the loosening of the door trim, and reduce the fatigue due to metal.

and the noise generated when the body twists. If it is only a four-door sound insulation, then the most obvious feeling it brings you should be the change in the feel of the opening and closing of the door, and the feeling of heaviness when closing the door.

Reduces the resonance of the door sheet metal parts due to the thin during driving, reduces the loosening of the door trim, and reduces the noise caused by metal fatigue and body twisting. If it is only a four-door sound insulation, then the most obvious feeling it brings you should be the change in the feel of the opening and closing of the door, and the feeling of heaviness when closing the door. If you choose an unprofessional tuning shop, the four-door sound insulation is likely to be ineffective, and it will also bring sequelae to the car.

Even change your car stereo sound.

It's hard to say, if you choose a professional modification shop, and the materials are relatively advanced, then the four-door sound insulation is generally not harmful; But if you choose an unprofessional tuning shop, the four-door sound insulation is likely to be ineffective, and it will also bring sequelae to your car, and even change the sound of your car.

It is worth noting that reliable materials must be selected for car four-door sound insulation, and there are many kinds of sound insulation products in the current market, and sound insulation materials are very critical. In addition to this, a professional and reliable tuning shop is also a must.

This depends on the specific situation, the shielding effect of four-door sound insulation for medium frequency noise is more obvious, but one point that needs to be reminded here is that the reduction of intermediate frequency noise will not bring a very obvious overall noise reduction, because the high frequency and low frequency noise still exist, but it feels that the direction of the noise has changed, which will improve the comfort level to a certain extent.

Hello, just do four-door sound insulation, the sound insulation effect of the car, the noise reduction is almost negligible, if the noise requirements are relatively high, you can change four silent tires. The effect is more obvious.

Is it useful to do four-door sound insulation, the details are as follows:

Useless. Sound insulation is effective in reducing noise in the car.

The shielding effect of four-door sound insulation on mid-frequency noise is more obvious. The reduction in mid-frequency noise does not lead to a very significant overall noise reduction, because the high-frequency and low-frequency noise is still there, but it feels like the direction of the noise ** has changed, which will improve the comfort level to a certain extent.

Sound insulation is mainly completed by rubber pads and cotton, the role of rubber pads is shockproof, the effect of cotton is sound absorption, the collocation of a single layer of rubber pads and a single layer of cotton belongs to the primary sound insulation, in order to improve the sound insulation effect, the number of layers of rubber pads and cotton should be increased.

** and basic understanding of noise.

The noise of the vehicle mainly comes from three aspects: the engine noise of the vehicle itself and the noise generated by the vehicle resonance; noise caused by the friction of tires touching the ground; Then there's the wind noise. These noises can be simply divided into high, medium and low frequencies, which can be understood as the noise generated when driving at speeds below 40km h; The midrange frequency is produced in 40km h-80km h; Above 80 km h, high-frequency noise will occur. To reduce the noise of different frequency bands, different areas need to be improved, and the sound insulation of the vehicle from the bottom up can solve the noise of low, medium and high frequencies, such as the best way to reduce the frequency noise is to do the chassis and fender sound insulation, and the medium frequency is the cabin, trunk, four doors and ABC column sound insulation, etc., we should choose sound insulation products reasonably according to their own noise ** and the area that needs to be improved.

Summary. Hello dear! We're happy to answer for you!

The pros and cons of 4-door sound insulation in cars are that four-door sound insulation is to paste a special soundproof blanket in the door trim panel to reduce the resonance caused by the thin door panel when driving, reduce the loosening of the door trim panel, and reduce the noise caused by metal fatigue and body twisting. If there are only four doors soundproofed, then the obvious feeling it gives you should be that the opening and closing of the door has changed, and there is a sense of heaviness when the door is closed. <>

Car noise is divided into low, medium and high frequency, and not all noise can be isolated as desired, while four-door sound insulation has an obvious shielding effect on mid-frequency noise. However, it is important to note here that the reduction of mid-range noise does not lead to significant overall noise reduction, because the high-frequency and low-frequency noise is still present, but the direction of the perceived noise source has changed, which will improve comfort to some extent. So, if there are only four doors that are soundproofed, some of the noise can be eliminated, but other noises, such as engine noise, chassis noise, tire noise, etc., will continue to exist.

Share a four-door soundproofing that I made with shock-absorbing panels and sound-absorbing cotton in Jindaosheng. --This part can play a role in blocking the outside noise, regardless of the urban overtaking, side by side driving the noise of the other party's vehicles, the highway high-speed driving wind dry, at this time the noise of the four doors is very large. After making a four-door sound insulation, the noise in this area will be reduced.

At the same time, it can also improve the sound effect of the car, because there are many holes in the door before, and the sheet metal is thinner, it is easy to cause the resonance of the steel plate to cause the sound distortion when the audio is opened, and the resonance of the steel plate is suppressed after the sound insulation is done, and the hole is blocked to form a box horn can show a better sound effect. The sound of the car door closing is also more pleasant.

Hello, during the use of the vehicle, if there is noise, you can consider doing it to the vehicle, and the sound insulation effect is still relatively good.

This depends on the specific situation, the four-door sound insulation has a more obvious shielding effect on the mid-frequency noise, but it needs to be reminded here that the reduction of the mid-frequency noise will not bring a very obvious overall noise reduction, because of the high-frequency and low-frequency noise.

It's still there, but I feel that the direction of the noise ** has changed, which will improve the comfort level to a certain extent.
