Does anyone know where I can obtain a noise reduction kit? I believe Acoustikit is no longer in business.
|

I purchased material from Acoustikit to cutup that was supplied for noise reduction. It seemed to be about one inch thick felt with a black vinyl coat on one side. I have heard of other materials where they have a thin lead layer inside the material to improve sound absorption. I wondered if marine suppliers would stock sound absorbtion material as engine noise in a boat is a big problem.

Try a product called Dynomat. It's proven to reduce vibration and deaden noise.
I've used it in small quantities for car speaker mounts and it's very, very good. Next project is to put some under the existing noise insulation on the bonnet.
It's available from any good specialist.

yeah, i've heard of dynomat, its really good stuff. I saw a demo in a car accessory shop where they stuck some to a cymbol (the instrument forgot spelling) and it made it sound like it was made of plastic. I was well impressed.
Its quite expensive though and would probably be able to get it cheaper from markets (Donnington Market near me is normally quite good for bartering)
They also make a foam version where you just spray it in cavities and it expands inside, but i've heard this isnt as good as the real McCoy.

John,
I'm interested to know what modern car needs a noise reduction kit. With the advent of effective "total design" in this area at the build stage, rather than throwing a bit of felt in afterwards, I thought such kits were only sold for old Land Rovers.
They're actually a waste of time in old Land Rovers really. They are needed granted but the felt is soon sodden this time of year.

Would that it was a modern car. Its for a Jetta 16v. Thanks for the suggestion of BJ.
|
John,
I had a new Jetta TX (pretend GTI) in 1986 and loved it.
Thought the noise of the 16V was part of the experience!

Dont spend a lot of money its not worth anything. You dont say what year the car is, but i will presume you have an earlier model without any damping under the bonnet.
go to a scrap yard and see if you can get a genuine VAG diesel underbonnet liner. This will reduce noise noticeably. Next go to www.falcon-acoustics.co.uk and buy some 2mm dedshete pads. USe thse at doubel thickness and stick to the bonnet before you fit the liner.
Most of the cabin noise comes throught the firewall. Covering this is difficult, unless you take the engine out.
Also, if you have a K&N, take it out. THese things make horrible induction noise and dont filter properly.

Sadly its not hard to find a modern car which is unecessarily noisy.
In fact its depressingly easy,even if the engine is acceptable the tyre noise wont be,or the wind noise,or.....
it might be excusable if we didnt have enormously long bonnets covering very short engines indeed. It wouldnt even be a problem if some of the space was filled with some sort of acoustically reflective material,but theres none in anything in my drive......
