hi navin,

from what i remeber, honda's ARE tinny. but it was the favorite cause no other car could match its peformance at the time.

i have had 3 ohc's. the type1 was good. i bought it as soon it was launched.(1.5l) the car felt solid. it went upto 1.5l kms and there were no rattles. then i got a black OHC type 2. it wasnt as good as the type1. i replaced it with an octy after driving 35k kms(it started rattling alot). still had another type2 ohc(all 3 1500cc) it was sold after 60k kms. this was the worst.

from my experience with the hondas, i can safely say these cars were difficult to ice. the front speakers would get as loud outside as it was in the car.

Next up was palio. amazing build quality. i used to only drive this car because the ICE used to sound really nice with no noise outside(no vaibrating boot lid etc)

now i drive a Hyundai Accent crdi. it doesn't rattle at all. no vibes from the boot, doors. even before damping the boot there were little vibes from the license plate. it has a decent build quality(better than honda IMHO)

This is my opinon so some one else' might differ. the ICE system was shifted from one car to another and the equipment through out was almost the same.

cheers

It should arrive in a day or two. Will tell you then. The catalogue has confused me.

I would assume the Santro would need as much as my mom NHC.

I used 8 sheets on the NHC, 6 on the Sail, 8 on the Octy (in addition to 2 sheets of Extreme but it a much larger car) and now I am actually thinking of redoing the NHC's front doors with more damping. The sheets we had we larger than 12" x 12".

Does the thickness of the sheet also matter?

not really but it's damping ability does. Sometimes thickness is related to damping ability.

Navin, from the photos posted by Sam, those AD sheets you have used looked like 1m x 1m (app. 3' x 3'). How much did the AD sheets cost you per sheet effectively?

Hot Tracks quoted (on phone) 1400/- per AD sheet, so the effective cost would be 155/sq.ft. Economical enough, @LBM?

I have been procrastinating for long damping my Safari (isn't too bad, but the FRP panels act up sometimes). Any idea how many sheets (3x3) would that take?

@B&T, how many sq.ft app. did you use in the Sierra?

IMHO, the panel resonance in cars also depends on the area without discontinuities, such as troughs and promininent fold lines. E.g. Santro and OHC doors are large plain panels, whereas Accent and Elantra doors have both troughs (for the door protection strip) and folds.

Yes sir it is ....but first check which area vibrate then damp it. no need to fill the car with damping in the first go. But the front doors are very necessary.

Not much in the Sierra. Never had anything exotic in the car so didnt bother. All the damping has gone into the company Palio and a little bit in the Wagon R.

Larger the continuous panel without any support, frame, fold etc, lower the resonant frequency and the potential displacement. Thats why when someone is on a budget, I recommend to use patches of damping to reduce the effective panel size.

For most cars, you need about 10-15 sq. ft per door to really toughen it up. Inner skin + door frame + door panel.

I think those numbers look right. I asked Sam (who was getting some for himself) to get me 24 sheets (4 boxes of 6).

BTW the NHC was the only car out of the 3 I damped that resonated so much that I may be forced to damp even the rear doors. I have a sft corner for the CVT tranny (for reasons that can be discssed on another part of this forum) but the car really needs better interiors and paneling. If Hyundai can do it why not Honda?

6x1400=8400. Doesn't sound too bad. Does it add a lot of weight to the car?

@navin, can you tell me how many sheets you used and where in the NHC? I have no idea about damping and you know what they say about imitation being the best form of flattery.

When you damp the trunk, is it only the under carpet area or the entire area including the sides and underneath the lid?

No it will not add too much weight..

when the boot is damped First I will go with the boot lid , second the side walls and lastly the under carpet area.

Whats a dampening mat?

[chiragh_bir]

these mats helps decreasing the un wanted vibrations caused by speakers or woofers

you can contact LBM/Gunbir for that.
