DIY Hoodliner Soundproofing

DIY Hoodliner Soundproofing

Hoodliner soundproofing is one of the best things you can do to your car today, to reduce the engine and road noise. In this article, I am going to show you exactly how you can sound deaden a car hood fast.

A noisy car engine is really unpleasant especially when trying to listen to your favorite music or trying to have a conversation with someone, Fortunately, there is a way to reduce road and engine noise.

Material Required For Hood liner Soundproofing:

  •  Sound deadening foam shield: There a lot of sound deadening foams that can soundproof a car hood, But it’s important to buy the right one, that’s why I included a guideline of what the soundproofing foam should contain. I personally recommend Noico 80 Mil (Click here to see the current price on Amazon)
  •  a pair of Scissors: The next thing you are going to need is a pair of scissors for cutting the soundproofing foam.
  •  A Roller(optional): This is really optional, you don’t really need it, but it will save you some time.

Guideline on buying a soundproofing Foam.

There are really a lot of foam shields in the market, Some are really Good but unfortunately, some are really bad and costly. Before purchasing a soundproofing foam shield make sure its:

  1.  It contains a heat barrier to help deflect the heat from hot temperatures and engine.
  2.  Strong adhesive to help stick the foam on the car under-hood.
  3. Thick this goes without saying that the thicker the foam the better.

I personally recommend Dynamat Thick adhesive sound deadener, From Amazon simply because of it matches the criteria for a good soundproofing foam.

reducing noise from the engine via hood liner sound deadening is really not difficult to do and it should take you no more than 2 hours (and yes you can do it yourself!). Follow these simple steps.

  1.  Open the car hood. This is self-explanatory.
  2. Clean the hood. You don’t need to use any soap/chemicals, water should do.
  3. measure the hood. Each car comes in different sizes and shapes, so it is important to measure before cutting the foam.
  4. Cut the sound deadening foam shield. Carefully cut the foam according to the size and shape of the car hood liner.
  5. Pull off one side of the foam. All you have to do is peel off the foam in order to use the adhesive.
  6. Stick the foam. Use the adhesive side of the foam to paste on the hood liner.
  7. Flatten the foam. Use a roller or your hand to make sure the foam it stuck and flat.
  8. Test the car. After all, is done, simply close the bonnet and test the car, by now the engine and road noise is reduced.

Dynamat hood-liner vs Fatmat Hood-liner

This is a very common question that is asked, and I will try to answer it in the best way I can, Both Dynamat and Fatmat work really well and it doesn’t really matter whether you choose to use Dynamat or Fatmat in your DIY project however, I think it is really important to know that Dynamat is slightly expensive than Fatmat. It is entirely up to you which one you want to use.
