Re: [T3] Sound Dampening Part II

you would be suprised how much noise comes from the engine lid in a square, but your right, noise does come in from all over. That is why i suggest having the inside sprayed with dynaspray or v-blok. Not only will you cover the entire interior and reduce a very good deal of noise,.but it also acts like a truck bed liner. It will help protect the metal underneath unlike the mat applications which can absorb water and retain it. I am removing my entire interior, and spraying the enitire inside,..door panels, headliner, you name it. Over the engine lid, i am pulling up the stock cardboard, and sprayin it, then puttin dynamat over top to replace the padding effect from the cardboard. Once the interior is replaced, you'll never see it. and the car will be quiet like a library.

Hi!

You have already discussed about dampening materials, but what are main
routes for noise to come in? I have Square, and to my knowledge engine
cover keeps noise out pretty well, but that piece of metal in cargo area
that is over transmission lets most of the noise in.

How about rear "door" panels or cargo panels? Where does all those cargo
panels connecting holes go to?

Have anyone studied this matter? I thought that best way to try find
noise routes out might be using plastic tube, another end to your ear,
another going around rear of the car searching biggest noise levels. I
just haven't yet got time to do it...

Any ideas?
