Car maintenance knowledge teaches you how to soundproof your car

carSoundproofThe product originated in the late 1980s and was produced by a group of AmericansCar stereoAudiophiles are developed to better enjoy the fun of car audio. These products can not only reduce the noise in the car during driving, but also improve the sound pressure and tone of the car audio. Therefore, car sound insulation was originally created for hedonists who really love cars. The purpose is to allow more car owners to have a perfect sublimation and enjoy more wonderful driving pleasure.Related reading: Do not "ring" the sound field to analyze the sound field and positioning sound of car stereo daily maintenance tips and four kinds of troubleshooting

Sound insulation function

1. Use sound insulation and vibration damping materials to dampen and seal the sheet metal of the car, improve the defects of the speaker installation environment, and restore the sound pressure and sound quality of the car audio.

2. Use sound insulation and vibration damping materials to reduce the noise transmitted by the automobile sheet metal structure and improve the driving comfort.

Sound insulation construction of car door

1: After driving the car to a safe place, apply the hand brake and turn off the flame to ensure safe operation.

2: Remove the interior parts in the order of first outside and then inside to expose the working surface. Put the dismantled screws and buckles into a special sealing plastic bag and mark the disassembly position, and put it in the designated place. Be sure to pay attention to the disassembly skills when disassembling, do not use brute force or excessive force to damage the panel and paint layer. All buckles must use a special buckle tool.

3: Use asphaltdetergentClean the work surface thoroughly, all dirt, grease, water, rust, etc. must be cleaned. When dealing with attachments (glue, glass fiber, etc.) that are difficult to remove, try to dissolve them with other special solvents and then slowly remove the attachments with a special spatula; or use a hot air gun to heat them evenly and then tear them off. Never use open flames or high-temperature heating at the work station, and it is forbidden to use corrosive solvents to prevent damage to paint and panels. Finally, wipe the work surface thoroughly with a clean cloth. When handling attachments, attention must be paid to the strength and direction of the force to prevent scratches on the paint and panels. After using the detergent, be sure to close the lid in time to avoid volatilization of the detergent and knocking over the detergent bottle.

4: First press the soundproof material into a mold on the working surface, and then use scissors or a paper knife on the worktable to divide it into the corresponding size and shape of the required working surface. If necessary, use paper to cut it into a model. Then unload. When cutting, try to avoid excessive splicing and repeated cutting.

5: Tear off the protective kraft paper on the back of the sound insulation material and paste it on the work surface. When the working surface is large, uncover the protective kraft paper while pasting it on the working surface, and then use a special roller to compact it. When there are air bubbles, use a paper knife to pick it up and press out the air so that the soundproof material is tightly attached to the work surface. Be careful when using scissors or paper cutters on the work surface to avoid cutting lines and scratching the work surface. Small materials and leftover materials should be attached to the parts with poor inner strength to further improve the sound insulation and noise reduction effect.

6: Reinstall the interior parts as they are from the inside to the outside. During the installation process, all parts must be reinstalled as they are; all screws and buckles must be tightened and fastened to avoid secondary noise.

Effect after construction

The sound of closing doors is obviously dull. When the vehicle passes over ridges, ditches and bumpy roads, the sound of the luggage compartment becomes solid. When driving at 60-80km/h, the road noise becomes lighter and smoother, and the external environment is introduced into the car. The noise is also significantly reduced; the sound environment is significantly improved, the bass effect is fuller, the level of music is enhanced, the high, middle, and low frequencies are very clear, and the sound quality is effectively improved.
