Any car has a huge number of different types of noise sources. In business class cars, great attention is paid to noise insulation. In cars that are mainly focused on the middle class, noise protection is not always enough. Sound insulation means damping the noise of the transmission and the engine, as well as reducing the vibration of the metal parts of the car when driving, which is achieved by gluing various materials to the body parts.
Instructions
Step 1
First, make soundproofing doors. To do this, remove the car door trim. It is usually secured with screws that are in the handle. Unfasten the bugs and detach the trim by lifting it up from the bottom. Disconnect the wires that fit the power window.
Step 2
Tear off the plastic wrap that was attached to the door at the factory. Degrease the surface. Cut and glue the outer part of the door (from the inside) with soundproofing material. Make sure that the material fits snugly to the surface, otherwise it will not have the desired effect, and when heated, it will fall off altogether.
Step 3
Seal up the factory mounting holes to create an enclosed volume for the best sounding of your speakers. Do this entire procedure with all doors. If you want, run the speaker wires at the same time to install the speakers in the door. Glue with thin strips the fit of the trim to the door.
Step 4
Next, perform interior soundproofing. To do this, take it apart to the ground. Apply a layer of insulation that will absorb vibration to the surface of the body: floor, arches, fenders. Then glue everything with a second layer, which serves to absorb noise. When assembling the interior, screw in the bolts that hold the trim in place to avoid confusion.
