Phewwww
Took me two days to go through the whole thread.
I am more knowledgable now on damping.
And got another positive point about owning a FIAT.
In my Adventure, there is some material in the engine cabinet, covering innerside by some material silverish in colour. Its the area between engine cabinet and car dasboard, below windshield. Over it there is a another layer of some fabric based product (thick black colored). Same black material is also on the bonnet.
Rest there is no such damping used in any of the doors. However the boot floor area is having a thick material of dense natural fiber, slightly greenish in colour. Its just below the matt. But in passenger cabin the floor is having only by a mat.
Now firstly what is that greenish thick and dense material, I have seen it in the forum being used by Gunbir in few of his installs for damping doors.
There is considerable road noise in my car. So apart from geting the butyl based damping material, what else could be helpfull in minimising this road noise. And would it require some work to be done behind dashboard (I don't want my dashboard to be opened)? Would this green material be more helpfull or i have to go for butyl based damping sheets.
Also damping material reduces the noises by decreasing the resonance of parts, but I am still not able to understand how it reduces the vibrations and rattles caused by something loose. Isn't it covers that part and stops one hearing the rattling noise instead of curing the cause.

I am listing down few rattling and sounds which i have known after going through this thread and my car. Gurujano, please provide your inputs.

1) Creaking vibrating sounds, due to overstretching of parts, loose parts.
Cure: Tightening and readjustments of the parts at body shops.
2) Road noise, due to tyre-road contact.
Cure: damping the floor.
3) engine noise.
cure: damping the engine cabinet.
4) Air noise, due to air drag at high speeds.
Cure: Buy a mercedec
5) Noise due to ICE being played in high volumes.
Cure: Damping the resonating parts.
6) Noise due to friction between rubber gaskets on doors and car body.
Cure: Clean and polish the rubber gaskets, or replace the gaskets.

Initially my car noise was cured just by cleaning the rubber gaskets, and applying polish on them. but now some creaking is also being observed. I suppose first I should get all the things done to cure noises by a body shop, and then damp the car.

2) Road noise, due to tyre-road contact.

also damp doors and change tyres to nylon belted from steel belted

3) engine noise.
cure: damping the engine cabinet.

and firewall.

I recently got my feista damped, front and boot. My concern is that damping in the boot was done on the inner side of the rear shelf tray, i mean to say from inside the car cabin to the parcel tray. I thought as the Sub is in the boot, doesnt it make sense to do damping of the rear tray from below the tray as the sound will be hitting inside of the tray from the boot. I hope i am able to make my self clear. Do you think that this is the way damping is done? Reason being that i still hear sounds from the rear when palying at high volumes.

Either the budget is the culprit or the patience and sensibility of the guy who did your damping is at a premium. Anyhow, maybe you can patiently complete what that guy forgot to do.

Get a sheet of closed cell foam (black shiny foam) and start stuffing in all nooks and crannies, especially the boot lid and wherever wires and cables are passing through. Also make sure anything loose in the wheel well area is stayed down properly. Put some double-sided tape behind the number plate.

No, damping is effective no matter which face of the surface is damped.

What i meant to say was that the Boot lid was damped but the rear tray was damped from inside the Cabin and not from the below (which is from inside the boot).
Well i spent 3100 on the front doors and boot. Dont know the name of the material but its the same Silver shiny sheet used everywhere in Delhi.

Is this something we can do by our selves?or does it have to be done by the ICE guy himself??My car has also some vibrations that can be felt once the volume is raised, suspect is the rear parcel shelf which is a thin plastic case for the accord.This cant take the load of the coaxials and then start to vibrate.

Nylon tyres have lower road noise.
