Sound deadening materials

[lansdownplace]

Hello all. I was considering what I could do to enhance my 412 and making it a bit quieter inside would be a real plus. It has standard carpet underlay, no bulkhead insulation and intriguingly closing the air vents has a tremendous positive effect on improving a sense of solitude when driving

What recommendations would you make to address this? I have had a look at few options on the internet, but as to whether they are effective or not, I have no idea

regards

Trade it in for a Blenheim 4 !

Or drive a Land Rover for a week and it will seem silent

Or buy a louder 8 track

Or wear a motorcycle helmet

Or fit Fraser Nash electric motors to each wheel

Or cover everything inside with Dynamat like on the Yanky custom car shows

Hope this helps :-)

Have tried one of the above!....does Dynamat work?

Yes - it works very well and makes the radio / 8 track sound better too !

I am very tempted to get an eight track, maybe Tadpole Radios could convert it to keep the 8track and allow it to connect to a modern stereo.

I am going to have a look at Dynamat later at the local stereogram shop

I glued sheet roofing lead to the petrol tank in my 411. It was very effective at stopping the sound of fuel sloshing around in the tank.

Sound is transmitted into the car by panels (side or floor) vibrating. You can either suppress the sound transmitted by the vibrating panel, or stop the panel vibrating in the first place, by adding mass to the panel. Lead does this very effectively.

I did what you're proposing on my Jensen CV-8.
You might find this thread helpful.
Wind down a bit to get past the nonsense and it becomes pertinent.
The attention I paid to the doors was also very effective.
