Sound Proofing

Hi All,

The one thing I've noticed since having my TF is that it's bloody noisy, which is fine with the top down on the country roads in the summer but as most of my driving is not that I just wondered if people had sound proofed their cars, their thoughts and experiences and if anyone can recommend any products/solutions?

I'm thinking of lining the doors, wings with that sticky back stuff to see if that helps. I'm probably going to replace the carpets soon so will see if I can fit anymore sound deadening stuff behind those too, that sort of multicoloured wool material.

I don't have a hard top yet, but if that will help through the winter then I'll definitely get one. Again, any experiences?

Thanks,
Ollie

Thanks for that. I'll have a look and see what I can find. The engine noise I can understand and live with it's more the road noise and general clattering of the car.

I went in someone's MGF a while back and I'm sure it wasn't as noisy, I would ask him but he was no MG expert and doesn't have the car anymore.

Totally agree with this. Pretty much all noises are reduced by a hardtop:-

The engine cover section behind you is filled with the hood that quietens the engine.

The window seals better and reduces wind/road noise.

The hardtop is better insulated, also reduces wind/road noise..... even improves acoustics.

Dynamat is good, especially applied to the doors inner skin. Builders flashing is pretty much the same stuff as Dynamat but works out a little cheaper,

Dynamat Extreme

I've just covered the entire floor, forward fire wall, and rear fire wall (including the engine access cover) with Dynamat Extreme and then Dyna Liner sound proofing. I'm waiting to remove the door skins and will also line the doors with Dynamat Extreme. One trap for new players is the fit of the OEM carpet, especially in the foot well and accelerator pedal with all this sound proofing. I may end up removing the Dyna Liner from the drivers pedal area due to interference. I haven't driven the car as the SCU is in the UK being refurbished but I will as soon as it comes back to Oz, and modify the lining accordingly. I expect (hope) that the road noise will be quite a bit less.
Best wishes fellas.

A hard top is the best sound proofing as most engine noise comes out of the boot lid grille and straight through the hood/plastic window. The more solid hard top and it's glass window significantly reduce this noise. It makes the car like a tin-top! No other sound proofing will do that much but may reduce harshness due to damping vibration of panels and doors,etc.

I used a dynamat type product on every exterior panel.. Applied with a paint stripper gun.. (Heat the product up until its near melting)

Also did the entire inside of my cabin.. (Complete interior stripped) every inch of metal

Both sides of the fuel tank cover

Inside the fuel tank area (tank removed then re-fitted)

Inside the engine bay

Inside the boot

Then applied 10mm closed cell foam over most of the areas on external panels

Then foam fitted all of the rear wings with fire proof expanding foam to reduce the engine noise in the car

Engine cover will be double glazed Lexan cover

I've spent about ÂŁ1,000 sound proofing my car because I plan to do long Euro trips in it and want it as quiet as possible

My car sounds like concrete when you tap the doors/wings now..

No idea how quiet it'll be yet though as it doesn't drive yet..

Quite possibly the most extensively sound proofed F/TF yet..
