Did a lot of this in my old Celica.
I used SecondSkin products. Firstly, I stripped out all the interior then I put down a vibration dampner mat called Damplifier Pro onto all exposed internal sheet metal. Where possible, always try and apply to the insides of the body panels. These literally absorb and dissepate the vibrations in the body panels. It is these vibrations that make most of the noise inside your car. Exhaust and wheel noise can also be reduced by concentrating on the wheel arches and over the exhaust tunnel. If this still istn't enough for you, then you can apply a closed cell mat. I used Luxury Liner Pro for this which is just placed over the vibration mat. This mat catches any airbourne noise that escapes through the vibration dampner and gives you that nice silent top end car feel.
The stuff isn't cheap but believe be does work.
If you don't want to go to this extent then the best areas to do is the doors. These are big areas of metal that can pick up a lot of vibrations/road noise. Soundproofing the doors will make an instant improvement in road noise. And will also improve the sound quality of the speakers as they will perform much better in a sound deadened door.
Have fun!!

But you are so much more attractive with your bald silvery appearance

Hi Geoffers, KUGA PETE and Gutbucket
Thanks Geoffers for the pointers. I did have to take the side panel off the rear of my old RAV 4 so I would imagine its the same process. A few screws/bolts and then some push fixings. From somersetdrew's post "took the opertunity of sound proofing the luggage compartment and behind the side trims around the wheel arch,s this has made a huge difference to the amount of road noise transmited in to the car and i would fully recomend it. While I had the car apart I took the opertunity of sound proofing the luggage compartment and behind the side trims around the wheel arch,s this has made a huge difference to the amount of road noise transmited in to the car and i would fully recomend it" Is this it I wonder?? http://www.focusdiy.co.uk/WestcoFoamInsulationUnderlay195415?category=underlay This I think will be my number 1 project as the driving dynamics are superb for the type of car but a quiet drive would be superb...

I would be interested in this too. the kuga does lack a little noise refinement!

Well at the moment it seems the thing to do would be start with the easiest... So does anyone know if that would be the doors? The bonnet? The 'shell' around the boot space? Under the boot space (rear tyre). It seems straight forward... pop the panels cut some shapes and use double sided sticky tape to stick them in and then replace. So has anyone removed the door panels etc and if so how??? Thanks from Kugapete (2)

Most good sound proofing vibration mat is self adhesive. Just peel the back off and stick!
The doors would be a good place to start. Also wheel arches and floor. Well, to be honest you could go on. A lot of noise, especially wind noise, comes through the roof! Dampning the bonnet takes out a little engine noise but a lot will still come in through the bulkhead.
You don't need to completely cover every millimeter of panel for it to take effect. As long as you can stick it to a good proportion of the panel or area you want to deaden then the mat will absorb the vibrations.
Heres a good video or two that will show it...
As it says...nuff said!!

thanks big fella. Also found out that there are two main sources of noise: Resonance - caused by the panels flexing which noise damping mats sort out, I think thats the sticky stuff like dynomat... anyways you only need 25-50% coverage on a panel to cut that out. Air sound - caused by road noise and wind. This is sorted using a closed cell foam. Closed so that no moisture gets in and makes the car smell. Commercial products have a sandwich of materials which 'decouple' the noise. As you have to apply the sound damping material to the panel first, then the closed cell over the top. This is sounding like a project. somersetdrew mentioned he did the boot area and rear wheel arches so I guess I'll start there as I think the wife would be concerned if I took the doors apart. It seems the hardest part of this is access. So any advice people have about removing door panels etc would be gratefully received. This site has a lot of info... http://www.talkaudio.co.uk/vbb/showthread.php?t=318019&highlight=sound+proof&page=2 Let me know if you guys are interested and when I get the Kuga (early August) I'll measure the sound before and after as well as taking pics.

Seems like a lot of effort for very little little gain to me, fair enough if the kuga was really noisy, but it isn't - it's quieter than my old Mondeo GhiaX (though I'm sure a brand new Mondeo may be quieter than a new Kuga)
Just turn the stereo up a notch, or fill the car with people? Or just get older so your hearing deteriorates like me!
Also noise deadening / sound proofing=extra weight=lower fuel economy
