Sound dampening the front door of a 2013 Prius+ (Prius V)

Applying Petec Bitumen dampening mats to my 2013 Prius+ (Prius V). Music taken from the youtube free library. Original sound was not usable, since my neighbours were using their high pressure cleaner :(. The effect of the dampening material is really impressive!

A little. Less high pitched. What really helped was putting thick alubutyl mats on the floor, beneath the carpet, and placing a new, thicker carpet on top of the old one. Now, it's a decent car from a noise point of view. Need yet to make a slideshow of that...

well executedvery informativeI guess you didn't place an inner membrane, but reused that plasticI assume you did all 4 doors; but how about the trunk door, wheel wells, spare tire well, dash and ceiling?

Did this reduced the interior noise while driving?

Did it make a huge difference??

I need decibels number. Not subjective feel
