I have noticed that I can hear the outside noises when the engine is off to the point where I think a window is open. Would dynomatting the door panels reduce a lot of the outside noise coming in? I know it will help from an audio standpoint so I was just wondering if road noise is an added bonus.

 

I've also noticed execessive noise...also like if a window were open....is this because something is wrong, or is it just me?

 

My guess is that YES dynomatting or cascading. will drasticly reduce noise. I'll tell you why. The time I was doing the the fake wood project that you have to take the door panels out, I was driving without door panels for a couple of days. Anyways there was so much noise, it was crazy. My assumtion is that if the door panels reduce so much noise, adding an issulation matt would even further decrease noise.

I don't have cascade, but this is a Site NSXNEXT gave me. Thank you Neil.

 

i think this is how acura go these day!
