Sound Deadening

Sound-deadening materials aren't just used in home and movie theaters, auditoriums, or music rooms. Cars can also be laid out with these materials to keep racket from the engine, loud exhaust sounds, and rattling noises down. At the same time, they may also help dampen vibrations and enhance the stereo system range.

These materials come in different shapes and forms. You can choose one particular type or combine different products for best results or maximum dampening effect. To help you choose the best sound dampening material for your vehicle, here's a short guide:


Damping mats are fitted onto the car's panels to deaden the sound. They can be made from a particular type of rubber. They may also come with adhesive backing for those constructed out of asphaltic panes. These materials can effectively reduce the resonance or frequency of the panels. They could also turn sound vibrations into heat.

How to best use damping mats: This type of sound deadening material is placed in-between door panels that are next to each other to effectively reduce vibrations. You can add damping mats in the engine compartment as well to minimize rattles and other noises. Mats that are placed under the hood come with metal foil backing. These mats are known for their high heat resistance.


Foams used to dampen sounds may come in spray form or in sheets. Foam sheets are used the same way as mats.they also cover the panels. But instead of converting vibrations into heat, they absorb them by dispersing vibrations all throughout the sheet.

Where to use foams: This type of sound-deadening material can be placed around doors and engine spaces, as with sprays. You can check the labels to see where the foams are best used when dampening noises and vibrations from the car.


Sprays used for sound-deadening come in cans that require the use of compressors and paint guns. These may also be packaged as aerosol cans. Sprays are often used as alternatives to heavy or bulky mats.

What to do with sprays: Like foams, sprays can be used for filling small spaces. This is because they tend to expand, pushing against the nearby panels. With this, they're able to absorb and disperse vibrations.


Made out of thick pane of fibers, this sound dampening material is typically placed beneath the carpet. It's not as effective as other materials in absorbing or minimizing sound on its own, but when it comes to improved thermal insulation, this is one great option.

How to use insulation: First off, you have to get the measurement of the door panels and carpeted sections of the vehicle. Based on this measurement, cut off the insulation and matting. The carpet should be pulled from the car's body to easily install this sound dampening material. The next thing you have to do is to apply contact adhesion glue to the car's body, where the mats and insulation will be placed. As you lay the material on the glue, be sure to press this with a little bit of force so it will stick. You may fill in the spaces with foam or spray for better results. Let the glue and spray sit for a while until it's cured or totally dry. Follow the manufacturer's instructions carefully.
