As I said before, sound will find its way in the car. Again, in our experience, and while there may be exceptions to the rule, it typically will not be worth the effort. When I tell this to people, they usually question if only doing the more general areas will be enough. It’s best to do the whole car if you are going to attempt sound-proofing in our experience. If you are going to apply a noise barrier to your floor, do not waste your time unless you can cover every area. For starters, 100% coverage is highly suggested. Using a noise barrier is relatively straightforward, and there are a couple of rules. It is also much thinner than previously prevalent noise barriers, making it the obvious choice to use in today’s vehicles. Our ResoNix Barrier is very flexible and holds its shape. 1/8″ MLV is very stiff and has no stretch, and does not conform well to bends and curves. Applying a noise barrier to sound-proof your vehicle used to be a daunting task. The new favorite among die-hard enthusiasts is encapsulated sheet lead.
Typically, 1/8″ thick, 1 pound per square foot virgin MLV. The most popular choice for this in the aftermarket car audio world used to be Mass Loaded Vinyl, aka MLV. As said before, to block noise, you need to have a limp, decoupled mass.
That said, those types of products still have their place, but let’s focus on blocking noise right now. You would need an absorbing material that is way too thick relative to the size of the car to do anything meaningful for road noise. Blocking will be the most effective way for a vehicle since blocking only needs mass with an air gap, while absorption needs a relatively thick open-cell or fibrous material. There are two ways to eliminate sound from entering an area blocking and absorption. Frankly, this is the most daunting and time-consuming yet rewarding task when sound treating a car. This part is what I refer to as sound-proofing your vehicle. Here is an excerpt from our Reference & Information Guide that explains blocking outside noise.Īfter you have lowered structure-borne resonance and eliminated all of the panel-on-panel vibrations, the final piece to the puzzle is to reduce the outside noise entering your vehicle. More info will be added as we get some spare time. No, your buddy’s favorite product with catchy marketing is not actually blocking your outside road noise. The point of a noise barrier is to block any unwanted noise from entering the cabin of your vehicle. The main purpose of this product is to replace a traditional noise barrier. It is a combination of two 3mm thick layers of our Closed Cell Foam that encapsulates a layer of 1/64″ thick, 1.25lb per sq/ft lead sheet.
ResoNix Barrier is a 3-layer, multi-function noise barrier product that is meant to fit in newer cars without the hassle and cuts down on installation time vs traditional noise barrier products such as Mass Loaded Vinyl. It is best not to wait until it is in stock. Please note that this product usually sells out before it even arrives to us, and we order small batches at a time due to the logistics of shipping and storage.
