Don't know if it's on the new Accord, but I've heard of it being in other Jap luxury cars. Ages ago I did a '06 Accord, two layers of sound deadener on every door panel and heaps in the boot. Once you were inside, you couldn't hear power tools being operated right next to the door :) mate thats great im planning to do it with the Aurion... once thing ive found with my Yaris... the BITUMEN PAINT if its dry will only take out the noises coming from engines going pass you... but does not some reason omit road roars... im planning to to supercheap and spray wet bitumen paint and cover it with domestic aluminium foils so i get more noise suppression for the Yaris...
