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

I am a safety officer by profession. I measured the sound level before and after installation. With Dynamite Extreme, the noise level dropped by 5 decibels. Some of the 1 star reviews complained that the noise level only dropped 5 decibels. The sound intensity doubles for every 3 decibel increase. So a 5 decibel reduction means you are actually significantly reducing the sound intensity with the Dynamat. Most of us perceive a sound as twice as loud as another if they differ by about 10 dB; For…

This was recommended to us by our mechanic to mute the sound in our RV. My husband was converting the van and we decided to give it a try as the loud engine noise made it very difficult to converse while the van was running. He lifted all the carpeting around the kennel, cut and fitted the dynamat to the entire floor area around and under the kennel (engine). The difference was incredible. Now we can easily have a conversation. It all seems a lot calmer. This stuff really works as it says. I…

Bought to compare with two other popular brands and install. Testing still ongoing but best stickiness so far but a tiny fraction thinner and a few bucks more. I would easily recommend this or any of the other brands (without intention so I can give a rating). It had the best grip and it was enough to be a good part of a compact car. You will keep 2 of these or you can build a bigger car. depends on your car. I layered anything that rattled when I tapped it. Buy a roller and not cheap. sticks…

The app is time and labor consuming. Focus on flatter areas first, they generate the most noise. Save the trimmings as every little thing can and should be used somewhere. I was skeptical of its ability to mitigate my trunk's horrific rumble, but was pleasantly surprised to see how much of a difference it made. The adhesion to these things is pretty intense, if not careful they can wreak a bit of havoc. The tape will help seal sticky bits in the trunk and other places you may need to climb in…

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…

I have a 2002 Mazda Miata like all Miatas. These are roadsters. They have wild roaring street noise, up or down. Okay, it's a convertible and you say it's okay. I tried to add insulation to the "Noisy Zones". Not good. I've tried many things to reduce the rumble and road noise. Hence the last cash injection for Dinamat. All I can say is "do it" and don't look back. My little Miata is so quiet that my wife and I can have a normal conversation with her WITHOUT raising our voices. Quiet is a…

I did some research before deciding on the Dynamat. There are some cheaper competitors out there that people swear are just as good, and they could be, but I just don't trust them that much. In fact, if you do your research, you'll find that some people have opted for roofing material that you can buy at Home Depot. Someone must have gone insane to put $20 worth of roof tar in a $20,000+ car. The only negative thing people have to say about Dynamat is that it's expensive, but buying big packs…
