Even more so if you’re trying to drown out the sounds of the road with the radio on. We all want a relaxing drive, and the sounds of wheels on road and the dull hum of whirring car parts can really take the joy out of driving. A solution to the transport tinnitus of car-based noise pollution is to layer your vehicle with sound deadening material. Not only is this one of the best ways to muffle your car from the inside, but it is cheap too, and takes up very little space. Below is everything you need to know about sound deadening your car, and some crafty tips to get the most out of it.

What is sound deadening material?

There are plenty of options when it comes to sound deadening your car. When it comes down to it, the focus should be on budget, effectiveness and aesthetics. Much like a car stereo installation, knowing what you’re looking for and need from your sound deadening will help you to make a great value and long-lasting purchase.


Insulation is a two in one solution for heat and sound. Installing these panels will mean that you can both deaden the external sounds and also deflect any unwanted heat in the car. This keeps you both cool and quiet and is best used for roofs and doors due to its condensed fibre made thinness.


Mats are a lot bulkier than insulation and are best used for floors of cars, or for general use in roomier vehicles. Mats work by converting the sound energy into heat energy, thus keeping you warm whilst deadening the noise from your vehicle.


Coming in either spray or sheet form, the insulation foam is light and works perfectly on the insides of doors. The spray is used through a compressor can, whilst the sheets of foam are place dover the car panels, absorbing the vibrations and sounds which come from outside.


A spray is a great source of sound insulation for those harder to reach or smaller areas of the car. Whether a corner crevice or a tight gap, sprays can be used for insulation due to their ease of application. Sprays are also lightweight, meaning that you don’t add much weight to the car.

What parts of the car should you sound proof?

So now you know the different types of sound deadening materials, what are the parts of the vehicle which need it the most?


The doors are a delicate part of the car so should only have insulation applied which will not add too much weight. Insulation is needed here to stop wind and mechanical sounds. You may also find parts of the car sound system here, and so don’t want to add any more weight.


The floor has space for bulkier sound deadening materials and can be prone to road and undercarriage noise.


The roof needs to be protected from heat and wind noise, it usually being rather thin and being closest to your ears!
