How To Reduce Car Noise

Your car noise reduction and car sound improvement questions answered by Car Insulation UK. 

"How do I reduce car noise?", "How to improve sound in my car?" and "how to reduce car cabin noise?"

Here you will find specialist advice when looking to reduce car noise along with advice on car sound reduction materials which are suitable for reducing noises from different irritating noise sources within your vehicle.

On this page we would like to offer some guidance on the different sound paths into your vehicle along with the suitable car noise reduction products to improve car sound quality. We have over 10 years industry experience in reducing vehicle noise and improving vehicle sound for some of the biggest and most prestigious vehicle brands in the world.  With this page we aim to save you time and money by helping you to fit the best car noise reduction materials in the right areas of the vehicle.  Some sites which claim to offer advice for example "fitting one branded product to the whole of the vehicle" is simply wasting you money as a car or vehicle has many sound sources which cause irritating noises, e.g wind noise, exhaust noise, cabin noise, road noise, tyre noise, engine noise, rain noise, stereo noise and outside noises to name a few.  Each of these potentially irritating noises vary in frequency and the routes in which the sound enters the vehicle.

We would like to provide you with an information tool kit for reducing noise in cars which guides you through some of the best noise reduction insulation products available on the market and matches their different acoustic properties with the relevant car noise problem.

1)  Plan you car soundproofing project. Planning your car soundproofing project is the starting point for your car soundproofing project.  A basic plan will help you to estimate timings and soundproofing material requirements, saving you time and money.

  • Decide the areas of the vehicle which require soundproofing and the order which you plan to soundproof them.  Consider the use of one soundproofing material covering multiple areas of the car and if the shapes can be nested together to reduce the amount of material required.

  • Research which car parts will need to removed and how to do this online.  Roughly plan the time it will take to remove the parts. (allow for 15-30 minutes per area cutting and fitting car soundproofing materials)

  • Plan the tools you require to remove the panels of the vehicle. (for cutting and fitting the car soundproofing materials you will only need a sharp knife / scissors and a board or area to cut them)


2) Choosing the right car soundproofing materials for the right areas of the car is the starting point for soundproofing your car.  There are many complex noise issues created within cars which cover most of the acoustic frequency spectrum.  


Usually soundproofing materials are split into three types. (click the links to the relevant categories)
  • Car sound absorption materials: These soundproofing materials reduce the sound energy carried in airborne noise.  Also known as automotive acoustic absorption material.

  • Transmission loss materials: These soundproofing materials act as sound barriers and reduce the amount of noise passing through the material. Also known as automotive acoustic barrier materials.

  • Anti-vibration materials: These soundproofing materials adhere to body panels and stop them acting as a reverberant speaker. When OEM's are constructing a vehicle which includes soundproofing, a panel dampening material is fitted which reduces the vibration of the vehicles body panels when they are excited by one of the many high energy sound sources caused when the vehicle is in use.

To successfully combat a complex noise issue and soundproof your car you usually require a combination of two or three material types to provide optimum acoustic performance.

3) Ordering enough soundproofing materials for the job. This is always key to saving time when soundproofing your vehicle.  If you need to remove seating or door cards the last thing you need is to run out of soundproofing material half way through the job and potentially pay shipping fees twice.
  • Consider the roll width of the material when estimating the quantity you require.
  • Consider the shape of the part you will create when fitting your car soundproofing, if the shape is rectangular or triangular could you nest this to reduce the amount of soundproofing material required?
  • Consider if soundproofing material off cuts could be used for different areas of the vehicle?
  • Once you have selected your required soundproofing materials check if you require high performance double sided tape to fit the products.
