Concentrate on flat panels if you dont have a big wallet. Convoluted panels generally vibrate less(higher freq) therefore mass loading is not needed. What you are doing by putting dynamat is adding weight to stop it vibrating and a little bit of sound blocking ability.
To be honest, there are cheaper products to use on the floor but dont let me stop you if you already planned it out. I dynamatted my spare tyre well and it didnt make any or much difference to road noise etc. Best places to use it is door panels, quarter panels. Sound dampening works several ways, its been a while since i played with audio but from memory... absorption: thick foam mass loading: bitumen etc(that black stuff on dynamat) blocking: that aluminium backing on dynamat so.... you mass load a panel to stop it vibrating.(add weight to it basically). Vibration causes sound = road noise.. or you block the sound by having a barrier.... dynamat does a bit of both. Get ready a pair of gloves and a hairdryer or heatgun and sharp raxor for the dynamat. You want to lay it down properly, the aluminium backing is razor sharp. This post has been edited by soven: Jul 9, 2007 - 2:27 AM |
