Car sound insulation does not mean that simply stuffing some items in the door panel will achieve the sound insulation effect. Since sound insulation must be done systematically, it is impossible to achieve the most effective sound insulation quality by just doing a certain location.

Partial sound insulation and complete vehicle sound insulation. The complete vehicle sound insulation effect is the best and the price is more expensive. Partial sound insulation is the most economical.

The complete vehicle sound insulation is said to be the most effective in automobile sound insulation. Yes, it is also the most expensive, but we do not recommend that all cars be soundproofed, because soundproofing new cars is actually very expensive and thankless.

For some cars, their own sound insulation effect is not low. It is possible that only a certain part of the sound insulation is not in place. At this time, there is no need to soundproof the entire vehicle, only a certain part is required. Doing some local sound insulation will have a great effect.

It is best to leave car sound insulation to professionals, otherwise it is very likely that the gain will outweigh the losses

If you want to do car sound insulation yourself, unless you have professional knowledge and skills, Otherwise, independent modification will not only consume a lot of time, but the results may also be unsatisfactory. For example, in terms of vehicle sound insulation, you first need to remove the door frames of the four doors, the wheel arches of the four wheels, seats, trunk interior panels, etc., and even the instrument panel needs to be removed, and then Installing various soundproofing materials and then putting the dismantled things back together means that the soundproofing system has performed an internal plastic surgery on the car.

Low, medium and high frequency noise are most effective in the engine, four doors and chassis

According to industry experience personnel, car noise is divided into low, medium and high frequency , not all noises can be isolated as desired, such as car engine noise, sheet metal vibration and other noises belonging to medium and high frequencies, which can also be isolated by sound insulation, and wind noise, especially exhaust pipes The sound belongs to the mid-low frequency and is often difficult to isolate. Therefore, the most effective parts of car sound insulation are the car engine, four doors and car chassis.

Finally, we advise car buyers that car sound insulation should be done according to the actual situation. I think it may not be necessary for new cars, mid- to high-end cars do not need to be done, and older cars can Yes, but you must go to a professional and reliable modification shop, otherwise it will be a waste of money in the end. This is my personal opinion and is for reference only. The decision-making power is still in your hands.
