He is quite right. Avoid taking out the roof liner.

One suggestion - but check the feasibility before doing it.
Take out the rubber beading & see if you can spot any gaps between the roof lining & the roof. If there is any gap, slide in a strip of butyl rubber damping sheet (sticky surface pointing to roof). Press it to stick. Give it a shot .. may help a little.

Question Re: The Damping Material and Sound Deadener Thread

1 x Dynamat-Xtreme bulk-pack ( 36 sq.ft )
2 x Dynamat-Xtreme door-kits
6 x Wurth damping sheets
...
So finally got the damping & the I.C.E (Car Audio Advice from the Audio Gurus: Use "Search thread" before posting a new Q!) installed in my car last week.
In addition to all the damping material already available with me, I had bought 2 more bulk-packs of STP-Silver for damping the car.
The floor, roof, doors, & hatch were all damped - I estimate that the damping material alone has added about 30 Kgs to the car, if not more.
Of all the damping material provided, only one of the DynaMat-Xtreme Door-Kits & the Wurth sheets got left out - everything else was used to damp the car.
The doors feel quite solid now & even at volumes high enough to liquify your insides, it does not appear that everything's going to fly apart.

That said, while the interior is now a much quieter space than earlier, there is still some road noise filtering within.

My query to the I.C.E folks is, what else should I be doing, from a damping perspective, to reduce road-noise ?

There will be some hidden small holes /gaps -esp in the firewall area - that cant be closed. Hence would suggest to let that be.

One thing I can still think of is - the wheels. Have you added anything in the engine-bay, around the wheel area.

Thanks, as far as I can tell, the wheel wells inside the car have been damped - should I damp the engine bay also ?
The thing is that the engine noise is now quite damped.
I used to have a very loud end-can, but recently I got a mid-muffler / resonator fitted to decrease the exhaust volume.
Now, after damping, the exhaust volume ( sound ) has decreased even more, the exhaust is just a muted note now, hence a tad sceptical that damping the engine bay will help.
Frustrated that even after using 3 bulk-packs ( ~116 sq.ft ) of damping material, road noise is still filtering in

You'll have to accept the fact that you have a car - not a soundproof studio. Some amount of road noise is going to filter in no matter what, all that damping only prevents certain frequencies and no amount of extra damping elsewhere is going to help further more. You're only pouring in more money and making the car heavier without decreasing noise.

Reminds me of Sanjay Gandhi's ambassador car.

Do you mean the (original, ugly) Maruti with Triumph engine? Had never seen him with an Amby (other cars, yes). He even wanted to get VW to manufacture Beetle in India.

Wasnt difficult to find the shop. But he was not willing to give less than 1 full roll. Each roll is 20m, and costs 1950 or so .. It did not feel very heavy.

Generally damping material like Dampguard or Dampmat Xtreme is used inside door pads to improve sound insulation, thereby improving sound quality inside.
I guess this is more appropriate in the Damping material technical section than here!

Came across Scosche damping sheets in my town (nothing else available here). Any inputs regarding the quality of these sheets and is it worth Rs.1500/- per sheet? Looks quite expensive to me.

I am getting quotes for ICE on my new Scorpio. The accessory shop is quoting 7500 for damping of two front doors with 3 sheet layers. Is the price ok? Seems a bit excessive.

Price is okay only if damping material is 'Dynamat extreme' else it is expensive.

It does sound a bit steep.

3 sheet layers? Do they mean outer, inner and door pad? Or do they mean 3 layers one on top of the other?

Check with 3M - even they are pushing damping, and they sound economical.

If you are going in for damping, damp all 4 doors and rear door. The rear door need not have sheets - rolled up closed cell foam stuffed between outer and inner metal layers is good enough.

I think he meant 3 layers one on top of another - but will confirm.
I will inquire about the 4 and rear door damping as you suggested - can you give an approx cost for the same?
