Review on 🔇 Dynamat 10455 Xtreme Bulk Pack: 9 Sets of 18"x32"x0.067" Self-Adhesive Sound Deadener, Black by Eric Young

After much sweat, hours and hours tearing Sienna 2013 incl. doors, floor, console, rear side panels. not much soundproofing. Very very disappointing. Really thought it would make a lot more difference. Next we will put in a quieter rubber. Maybe it's the ticket. It should be added that all of the seats are out the back of this van, except for two that slide out of the floor at the back. This is one of the reasons for the high noise level, but not the whole reason. It was always noisy. Unacceptable levels when driving on various highways, e.g. B. the northeast extension of the PA Highway en route to New York. Terrible road there. I will say that I put the dynamat in the box with the console, put my phone in there and barely heard it ring. So it works in certain applications. Too bad it can't be installed on Windows. Next time it will be a luxury car that comes with all the noise-cancelling devices from the factory. It matters, but not the difference we were hoping for given all the $$$, time, and work.
