Sound deadening

[Ron40]

Does anyone have any experience in sound deadening a car, what products to use and were is the best place to put it, I have heard of Dynomat but I believe its really more for vibration for loud music in a car to get a better quality sound, this is not what I am after , I am hoping I can quite [ some ] outside noise & engine noise.

thanks

Dynamat is what you are after, it's for reducing noise.

How much will Dynamat quiet my car? Even a small amount of Dynamat can cause a profound noise reduction. For example, applying Dynamat to the doors of your vehicle can reduce road noise from 3-6dB!. Complete coverage of an average vehicle can reduce road noise 9, 12 even as much as 18dB.
