SOUND DEADENING. TECHNICAL STUFF :)

[depz]

Hey all!

I want to sound deaden my 1998 316i coupe. I heard that the cheapest way to do it is to stuff the door panels and everything with cotton wool which is really effective and costs next to nothing. does it really work? is there anything that works better?
i dont really want to spend anything on it past £15 cos im a cheap arse


Any info/help/ideas would be well helpful and appreciated.

hhhmmmmm....not sure about that one, every time you take the window down your gonna be compacting it and if its a wet window even worse!!

so why doesnt dynamat do that?

what about sticking it to the sides with brown tape (you know the card board box stuff) or using foam carpet underlay??

Just a thought.

Dynamat and like products are water-proof rubber/butyl/asphalt based products.

they use mass to absorb vibrations and resonance.

It's not cotton that people use, its Polyester Fiberfill (stuff used in stuffed animals and pillows)

Fiberfill, Cotton or the like will insulate, but will not absorb vibration or resonance.

Also, it will absorb moisture and keep in in between panels. This will eventually result in premature rusting/corrosion within the spaces where it is used.

Stick with products designed to do the job right.

you should get the stuff they use in payphones around the base that shit makes it so u cant hear nothing

what stuff is that? dont think we have the same foneboxes in the UK (ours are just metal dug into the concrete)

2 be honest ill probs just buy the dynamatt..just wondered if there were any alternatives.
