Sound deadening on the cheap, no audio equip

To block the noise the equation goes like this:

- Cover 25% with Mat on flat areas of metal panels (to prevent reverberations)

- 1 layer of CCFoam (to absorb high frequencies that still penetrate treated panels with Mat)

- 1 layer of MLV (mass loaded vinyl - 1square foot = 1 pound) to BLOCK the noise


I would start with

-Floor and wheel wells (all 4)

-Doors

A very effective and cheap area to treat are the front fenders.

and last... trunk

Sweet, thanks for the detailed information. How much would the above roughly cost and where would you recommend buying them?


Also, how would I go about treating the wheel wells and front fenders? (I'm pretty auto illiterate. I don't even know how to change my oil which is ironic considering I'm an engineering major )

Start with this LINK Don it's very nice to talk to, he thought me a lot about how to deaden my car.

You can also order from: http://www.soundproofing.org/

How much? well that depends on how much do you want to do. It's not cheap and it's heavy.

For the front fenders you can read post # 908 in my thread. LINK

Front wheel wells are not as difficult like the rear ones, just start taking panels out, then the carpet, and if I did it you can do it!

Remember that a continuous, uninterupted layer of mass MLV is what you need to block the noise. I remember when I was treating my car, it was like a game, chasing the noise from one side to another, it's until I covered everything that the road noise goes to a minimum. And I did a mix on blocking road noise with improving the interior of my car for a sound system.

I hope it helps.

That helps a lot actually. Thanks derick

Final question, about how much total weight (after everything's done) will this add to my car?

You are welcome...

At least 1 pound per every square foot of MLV. Mat or CLD Tiles are not as heavy but add weight, I'm guessing I have about 200 pounds but I love it! in summer I still get 42.4 MPG in winter it's around 39 MPG

The other day I picked up my Mother at the airport, she has a Yaris too, and her husband has a BMW 3 series, and after 5-10 minutes in the car she turns at me with a very frustrating voice...

"Your car feels so quite and smooth more like the BMW not like my Yaris, or even better!"

Yes, it feels good!
