Sound deadening
Sound deadening
I wonder if anyone has tried installing sound absorbing felt / extra resonance pads (the self adhesive ones) in their Fulvia to reduce road noise at motorway cruising speeds? I'm sure we'd all still like to hear the engine of course......
Re: Sound deadening
have no yet done this on my Fulvia - but it is something I intend to do. On my fathers Aurelia we did the following:
sound absorbant felt ( actually sold as anti-drumming material), which is self adhesive and when heated can be molded to the panel shape ( including indents and groves). It is about 2 mm thick.
Proper sound deadening material was used on the roof (about 6 mm thick). This is not self adhesive and you must use a specialist high temperature adhesive for this as the roof is a heat sink (especially on a dark car). My father used one from Locktite, otherwise in hot weather the adhesive will fail and the material will sag.
The actual decibel reduction was not measured, but subjectively it is quieter

Jim,
My car is currently in a million pieces in Auckland, undergoing a very tortured restoration. The fulvia originally had cardboard sound deadening panels glued into the roof, and a series of sound absorbing material panels on the firewall and around the transmission tunnel (series 2 coupe). The doors have a tar heat applied material along with some sponge pads. There was also material under the rubber mats on the floor (perfect for retaining moisture and promoting rust).
Without all of this the resonance and general noise is pretty nasty so it is well worth re-installing it all unless it is a race car. My car is currently being painted so replacing all of these items will commence again soon. I will research what is available locally and let you know what I find..
Regards
Chris
