Sound proofing a TR6

[fisicx]

If been considering soundproofing the car this winter when it's not out and about quite so much. There is however a huge range of products and I'm not sure where to start or even if it's needed.

 

Some of the product are horrendously expensive and some people suggests it's a waste of time.

 

Has anyone sound-proofed their car?

 

If they have did it make any difference and what product did they use?

It's a complex subject and there are at least two "kinds" of sound contributing to the noise level in a car. Methods to reduce one kind of sound don't necessarily reduce the other.

 

One kind of sound is that generated by panels when they vibrate. This kind of sound is often treated by adding a dense, pliant layer to the panel to increase its mass and to absorb some of the vibration energy. This serves to "deaden" the panel. The factory used those bituminous pads in various places, but there are more modern products that reportedly perform better.

 

The other kind of sound is transmitted sound like engine, road, or wind noise. These usually require barriers that are thicker, lighter, and more porous, like carpet underlayment.

Waste of time and money. Spend it on something else.

Fair enough. I'll cross it off the list of stuff to buy.

 

Still need new carpets though. Mine don't have patina, the word to use is 'motheaten'.

You have a choice on carpets. Expensive wool ones or the cheaper tufted nylon. There's a school of thought that says go for the cheaper ones because they'll get wet and you won't cry so much when they need replacing. That's the choice I made and ironically the car is watertight and they've never been wet. d'Oh!

Following a similar thread on Land Rover forum my son stuck black bitumastic panels all over the insides of the cabin and under bonnet area of his Landy and it made a difference, but not enough to make it worthwhile in my opinion, It's now just very noisy compared to very, very noisy before.

The best noise reduction I did on my 4 was....... poly bushes in the suspension! The amount of vibration and rattling was dramatically reduced. The rest, hood down, is mostly wind noise and buffeting. There's not a lot you can do about that. Hood up its much quieter but the hood drums at anything over about 55 - which is most of the time.

Why not wear noise canceling headphones?

 

They only reduce repetitive noise such as the beat/drone from the engine, fuel pump and wind noise, and passing traffic.

 

Wearing them you can still have a normal volume conversation and hear emergency services sirens etc.

What about the repetitive noise from the passenger seat?

Yes there are many a male of the species,with TRs, that go on and on and on........!! I've met a few of them over the years.

 

What is happening to this club? It's going downhill fast in my view.

The TR6 is what it is. It's a very good traditional British sports car where the design concept go back to the 1930's. Like all traditional sports cars it will be be noisy which can be difficult to change. However, having said that chances are if the car has been rebuilt most of the factory sound deadening material will have been remove. If this is the case then retro-fitting sound deadening may help.

 

Some of us now, old age, drive the TR7 as they a quite and comfortable. But then it is non-traditional and not to everybody's taste.
