i'm doing soundproofing for my pc

1 roll of hoodliner
1 dampening mat

some question...

1) the dampening mat, wut is the material

2) can u give me a link to vibraton dampener material comparison, i cant find

3) y u recommend it only for floors of cars instead of doors, does it melt or sumthing?

I m planning to put two layers, 1st layer dampening type, 2nd layer absorption type:

Sidepanel 50x60cm 3000cm²
Sidepanel 50x60cm 3000cm²
Mobo Tray 50x40cm 2000cm²
Roof 20x60cm 1200cm²
Floor 20x60cm 1200cm²
Total to cover 10400cm²

1) i assumed hoodliner is from dynamat company not soundblok...
from dynamat specification... hoodliner is open and close foam both.... its urm hybrid i guess
so urs must be some other company

2) For the 2nd layer, hoodliner is expensive. Noise Absorption Mat - 1 piece (~3'x4', thickness ~1inch, Open-Cell foam) and Insulation Foam - 1 piece (3'x4', thickness 5mm, self-adhesive, Close-Cell foam)
which one u recommend for my pc, close or open? wut the difference?

3) anyway do u sell promat <--- close type foam

4) for 1st layer, dampening, i want to use dampening mat coz its so cheap, is it the same as sikadamp, dynamat that other ppl using

5) i dont understand suppression pad and propad, it doesnt cover the whole area, just patch here and there how to stop sound???

very insightful, i ll get back to you once i have my pc. planning to buy after raya...
