How to Make a Car Interior Quieter

One way to improve the comfort of your car is to make it quieter. Soundproofing a car involves a great deal of effort but the end result makes it worthwhile. A quieter environment inside the car makes it easier to enjoy your favorite music, carry on a conversation or simply enjoy the peace and quiet as you take in the sights. Research the variety of sound insulation options for cars and trucks. A variety of products are available such as mats, multi-layered foam insulation and aerosol sprays. Set aside a weekend, purchase the appropriate materials, and by Monday morning, you will be able to enjoy a more peaceful drive to work.

Things You'll Need

  • Automotive soundproofing materials
  • Adjustable wrench
  • Screwdriver
  • Masking tape
  • Markers
  • Gloves
  • Measuring tape
  • Contact adhesive
  • Mild detergent
  • Cloth
  • Remove the seats in your vehicle. The seats are connected to racks that slide back and forth. Unscrew the bolts with an adjustable wrench. Set the seats in an indoor area or cover the seats with plastic tarps if they are being stored outside.

  • Pop off the plastic panels in the interior of the car using a screwdriver if needed. Number and mark the back of the panel with masking tape. This makes it easier to replace the panels after you have installed the new insulation.

  • Remove the old insulation from the interior panels. Protect your hands with gloves.

  • Measure the length and width of the panels with the measuring tape. Cut soundproof mats that fit the panel dimensions. Attach the mats to the panels with contact adhesive. The matting material reduces road vibrations and absorbs low frequency noises.

  • Spray hard-to-get-to panels and crevices with sound insulation spray. Follow the instructions on the can. Clean the surfaces before applying the insulation.

  • Mount foam noise barriers underneath the carpet. Choose from a variety of noise barriers of different shapes, sizes and thicknesses to reduce road noise.

  • Replace the panels and car seats in the reverse of how you took them out.
