Not recommened.
They are not meant for engine bay area.
In some specific cars, there are manufacturer provided Engine Covers which help in damping the engine sound to a decent extent. Not sure if they are available for all cars.

I am refering to the fabia here, which has an engine cover for the diesel available, albeit at a cost which'd make you think twice

I saw that in Safari also, will check if that can be done in a petrol engine car.

I got the front doors of my i10 damped from galaxy,cochin. they charged me rs.1700 for both doors. only the first surface was damped, not the inside of the door.

oh yeah, the damping material used was noisekill.

I went to local market in Faridabad for damping, no one knows what damping is . One guy told me he can do it for 1300 full car, material he was going to use was same as black foam kind of thing used in car A/c's , Will it be good to damp with that material?

I think they use closed cell foam to insulate car a/c pipes. CC foam wouldn't absorb moisture.

CC foam rolled and packed is good only to reduce rattles in some places (like hatch/rear door/boot lid), but pasted on large surfaces it does not have a significant damping ability. Check with our dear old Dr. LBM Singh Freedabadwale (low_bass_makker), and he can point you in the right direction in Faridabad.

Need to get my car damped as its messing with the sound, even at the lowest volumes, my doorpads have begun rattling.

Could someone suggest a good place for damping in South Mumbai?
And if possible, what is the cost im looking at?

My installer quoted-
Rs. 1200 per door and
Rs. 1400
for the boot of my Fiesta Sports
The brand he said is Kicker, is the price quoted justified?

Revisiting an old thread.Gurus kindly advise

I recently installed a pair of Bull components in my swift along with a pioneer 3250 HU.
I was told that , since I'm not installing an amp I wouldnt require any damping.
Now the issue is that when I crank up the volume , my door panels start to vibrate, a lot.

Searching the forum I learned all the brands of damping materials but I dont want to spend a lot at the moment.

But recently I came across this brand called Wurth, which I understand has been used by some of the bhpians here.

A direct deal from the company is being offered at an attractive rate of about Rs.2400/- for a pack of 6 sheets of 21" x 10" ( http://www.wuerth.com.ph/Catalog/WPI%20006%200005.htm ) The first one in the link catalog.

Is this worth in this price bracket ?? or shall I look elsewhere/alternate option cheaper option ?


Cheers

GT

Question Damping question:

Does applying patches of damping material, instead of covering the whole area, on the inside of the outer door skin produce good result? Shouldn't this work to cut down resonance and vibrations and be effective?

Depends on the size of the patches applied. Small ones like the size of one's hand or smaller are unlikely to make any difference. Swathes of 10-12" wide damping sheet would. That's how one does it - it would be *very* difficult to put one large sheet otherwise at one go.

I'm talking about not covering the entire outer skin of the door. But applying patches like in the picture below. Random patches here and there.

@ sankar

I was also about to do the same with wurth sheets which have the dimensions of 22'' x 9 '' by slicing them in pieces , lemme know if this works out for you.
