Most effective and affordable ways to sound-proof your car

Repetitive noise while driving is annoying, but how can you prevent different types of noises around your car? Click for the most effective methods for a quieter cabin!

If you are driving one of those luxury vehicles like the BMW 7 series, the Audi A8 or Roll Royce, congrats, this problem is totally unrelated to you. But many of our readers don't have that privilege. We buy a car mostly because it serves one of our specific needs and we're willing to pay an amount corresponding to those features, no more, no less.

Since most people aren't lucky enough to sit on luxury cars, sound-proofing is clearly an issue

Knowing that demand, car manufacturers only focus on what we truly need and somewhat neglect other factors. In this case, they did not really care about the annoyance from the sound of the engine. That distinct sound is not particularly loud, but prolonged exposure to it could be annoying, especially on a long journey. 

Sources of noise and how to deal with it

It should be obvious that you must first locate where the noise comes from before researching deeper. Generally speaking, 90 percent of the noise comes from the engine, but it has to transfer through several components before reaching our ears. Here are some of them and how to get rid of those excessive, repetitive noises.

1. The hood

The first component that not only transfers the noise but even amplifies it, the hood. Located just above the engine in most cars and are often made of metal, this is a perfect "instrument" for sound transferring. But thanks to recent development in the engine production technology, the sound generated from the engine becomes much more lenient and soothing.

Made from metal, the hood is a 'perfect' device to transfer, or even amplify the noise that bugs you

The sensible way to get rid of sound is, of course, get your car soundproof. Unlike those fancy sound absorbing pads you would see on a luxury studio, those that are used on a car are relatively simple.

First, make sure that the sound is factually generated from your hood. Second, go to an auto service and buy a roll of soundproofing material. We recommend you use the Fatmat, but you could get what is available in your area, as long as they serve the same purpose and have a similar thickness, which is around 80 mm, and also a similar noise-canceling pattern engraved on (so that it can trap noise inside and let them fade away naturally).

This material is a self-adhesive one, meaning it could be able to stick itself to the hood without any additional external adhesive. It also comes with a manual and a toolkit so that you can learn to use it in no time.

2. The window

Let's be honest here, none of us would enjoy the artificial coolness by the AC, especially when the weather outside is calm and soothing, or when our path happens to cross a countryside road. I think it's safe to say that 99% of us would lower the windshield down and let the breeze from mother nature caress our face and body. Sadly, it's not always the breezes that get into our car, but rather strong winds. Not only it would interfere with our driving process, but the noise generated from the wind smashing against the window would also be annoying too.

We all like to feel the cool air outside but that usually comes with other problems...

The best course of action here is to get your windshield stratified and the extra layer of this type of window glass would do wonder with wind noise. If laminated windows were not in your car's standard package, you can get yours turned into one in an auto shop, and it's relatively cheap too. 

3. The floors 

This is actually understandable. When we drive, almost all of us would feel the vibration from underneath transferred through your legs. Most floors come with thin carpets and thus not enough to reduce the vibration from the metal platform. So what you should do here is pretty much the same as the method you applied to the hood - get a different carpet or put another one on top of the old one you are using. Just make sure that the total thickness is sufficient to absorb the noise. To save time and energy, you should buy a block of Fatmat for your hood (as mentioned above) and use it for the floor.

You would probably guess as the vibration from the floor is very easy to feel

4. The doors

We put this one last because of its complication. Unlike other parts like the hood, the floor or the window, getting your car doors sound-proof would involve its complete and total disintegration and so most motorists would shy away from this method and only resort to it when all other methods are not effective. Most people would not need to go this far to get their car sound-proof, but we think it should still be introduced for reference purposes.

This is pretty extreme, so only do it when none of the mentioned methods work

Other sound-proofing methods

Get a new sound system

If you can't reduce the annoying noise, better suppress it by a louder and pleaser one. In this case, you should equip your car with a new, advanced sound system, so that every one of your favorite songs would act as a mini sound-canceling device that helps you feel relaxed, and at the same time kill the noise that has been bugging you ever since. 

Frequently Asked Questions

1. Does sound-proofing work at all?

This is one of the most, if not the most, asked questions regarding sound-proofing your car. After all, it's a reasonable question since no one wants to put extra stuff on your hood and floor only to find out that they're ineffective. First of all, let us guarantee you that all the things we mentioned above do work, otherwise, we would not categorize it here. On the other hand, if you expect an utter sound-free environment after installing all those, you could be disappointed because the purpose of those kits is to REDUCE the sound, not eradicate it completely. If you think about it, not hearing any sound would actually be dangerous since you need it to feel the environment around and thus navigate safely on the road. 

2. How should I purchase sound-proofing material online?

The short answer: like the way you would do with brick-and-mortar businesses. The long answers are you should do thorough research, from what type of material cancel noise the most effective to its average price tag. Even though the widespread of the internet has driven down the reference price significantly, there's still some dishonest business owner try to trick you with their words and all. So please do yourselves a favor and really know what you're getting into.

Scammers and also greedy business owners are everywhere, so take care 

If you have already searched for countless hours and still feel not satisfied, maybe it's time to do it on your own. If craftsmanship is your strong suit and you have plenty of time at the weekend, you could search for raw material and design a one according to your taste. It will cost you a lot of time but much less money.
