9 best sound deadener
Sound deadeners, also known as automotive soundproofing materials or automotive sound deadening products, are designed to reduce or eliminate noise and vibrations in vehicles. These materials are commonly used in automotive applications to enhance the comfort and quietness of the interior cabin. Sound deadeners play a crucial role in minimizing road noise, engine noise, and other external sounds, providing a more pleasant driving experience.
There are several types of sound deadening materials used in the automotive industry:
Asphalt-Based Pads: These are thick, heavy pads that contain asphalt or bitumen. They are effective at dampening vibrations and reducing noise levels. Asphalt-based pads are often used on the floor, doors, and trunk areas of vehicles.
Butyl-Based Sheets: Butyl-based sheets are composed of rubber-like materials known as butyl rubber. They are flexible and adhesive, making them easy to apply to various surfaces in a vehicle. Butyl sheets are commonly used on car doors and other metal panels.
Foam-Based Insulation: Foam-based materials, such as closed-cell foam, are lightweight and provide both thermal insulation and sound dampening properties. They are often used in automotive interiors to absorb noise and improve insulation.
Spray-On Sound Deadeners: These are liquid coatings that can be sprayed onto surfaces. Once dried, they form a thick, rubbery layer that reduces vibrations and noise. Spray-on sound deadeners are versatile and can be applied to irregular or hard-to-reach areas.
Mass-Loaded Vinyl (MLV): MLV is a dense, flexible material that offers excellent soundproofing properties.It is often used as a barrier to block airborne noise and is particularly effective in reducing low-frequency sounds.
Automotive sound deadeners are typically installed during the manufacturing process, but they can also be added to existing vehicles as aftermarket products. Proper installation of sound deadeners can significantly improve the overall driving experience by creating a quieter and more comfortable interior environment. These materials are widely used in various vehicles, including cars, trucks, and recreational vehicles, to enhance sound insulation and reduce noise pollution inside the cabin.

User questions & answers
| Question: | How many sheets come with the 36sq kit? I do see they are 20x |
| Answer: | Not only that it has SSD mounts but it is really easy to use them. They slide in and out of the case and can be locked into place. You simply slide the mount out of the case, install the SSD, then slide the mount back in and lock it. This is a really nice case. |
| Question: | How effective is this to reduce vibrations |
| Answer: | the case is deeper than it is tall. |
| Question: | Will this product help with the high pitched noise from tires on the highway |
| Answer: | No but you can purchse a 2.5'' media card reader front panel adapter for ~$25 which will fit and works just as well. |
| Question: | I have a portable air conditioner that is really loud. If i wrap the unit with this will it quiet down |
| Answer: | It should, especially if you do not mount a side fan. The case has a particularly wide clearance because its side panels flare out. It probably has more clearance than most.I installed a Hyper 212 EVO in one. |
Dynamat 10435 12" x 36" x 0.067" Thick Self-Adhesive Sound Deadener with Xtreme Door Kit
Dynamat
Product description
Stop fighting engine rumble, speaker rattle, road noise and buzzing vehicle parts! Apply Dynamat Xtreme to your vehicles resonant surfaces and enjoy improved clarity, loudness and bass response from your car stereo. High-performance Dynamat Xtreme is lighter than Dynamat Original, four times more effective, requires no heat to apply and is recommended for vehicle tops, sides and contoured areas. Dynamat Xtreme is coated with aluminum for high temperature areas such as firewalls and floors. Why does your car stereo sound louder when you pull off the freeway and come to a stop? Road noise steals much of the listenable portion of your music. At 70 mph, a typical automotive noise level of 85 dB leaves you with only 20 dB of listenable music. Applying Dynamat creates a "sonic barrier" restoring 3, 6, even 12 dB of lost dynamic range. Gaining just 3 dB doubles your effective amplifier power. And that means you hear more music. Kit contains four 12" x 36" (305mm x 914mm) pieces of Dynamat Xtreme and includes enough material for two standard size doors.
- This kit contains four 12"x36" pieces and includes enough material for two standard size doors
User questions & answers
| Question: | Will it stick to wood surface and metal surface |
| Answer: | It's 36 square feet. 36 - '1 foot by 1 foot' sections. Measure it. It depends on how well your going to cover everything. I covered every square inch of my vehicle including wheel wells, under carpet, rear hatch, 2 layers on the doors, and my hood and used 3 bulk kits. Didn't get to do my headliner and that would probably be 1/2 kit or a little more. You could also get away with just covering large open areas and use less. If I were you get 3 or 4 and you can do your fenders and hood too. |
| Question: | Hi, Is this the original silver version or the new black |
| Answer: | Normal Dynamat Xtreme will help reduce resonance of the metal. However, it will not really stop the low frequency pulses that the Kubota will generate. If you want to try blocking this type of noise, you are better off using the the Dynapad product and line all the floors and walls of your cab. The Dynapad does not have self-adhesive side, so you will have to use some kind of glue or adhesive to apply it to the vertical walls. However, this is likely the best you can do inside a vehicle. It's 3/8" thick and pretty heavy weight. If you don't want to do this, you can try the 1/2" Dynaliner, which does have an adhesive sticker backing and it's lighter, but will not block as much low frequency pulses. |
| Question: | can you use this on your exhaust muffler |
| Answer: | I used 2 boxes to do the whole floor , all 4 doors and the back of the cab in an Ford. F 350 truck |
| Question: | I have a Gas Club Car Carryall (Golf Cart)....My question: Would this Thermo-Tec be of much use to dampen/deaden the engine sound from my golf cart? I am considering placing some under the bed of the rear of the golf cart, under the front seats, and even possibly the floor board of the golf cart. Would this work good |
| Answer: | I also have a 2012 Hyundai Santa Fe and it was enough to cover all four doors, the tailgate and a few extra small places...you definitely would need 2-3 boxes to cover everything...But also keep in mind, you only need roughly 25% surface area coverage to be effective. No need to over do it! (2 boxes would probably be enough)You can check out sounddeadenershowdown dot com for a better explanation! |

| Question: | I have a carrier comfort apu 2 cylinder kubota diesel generator mounted to the side of my big rig approximately 95 decimals how much reduction |
| Answer: | If you look to eliminate the road, engine noise and metal vibrations then Noico 80 mil material is the way to go. You are to install Noico 80 mil to such key areas, as floorboards, doors, firewall, roof, trunk + trunk lid, rear deck. We recommend to carefully prepare the metal surface before installation of deadener to it. That would include thoroughly cleaning, drying and degreasing the metal surface before installing the sound deadening to it. You are also to firmly roll down the sound deadening mats to the metal surface with aid of roller. *Ambient temperature upon installation should be not less than 60 degrees F. If a temperature is lower than 60 degrees F then you are to preheat both, metal surface and even deadening pads up to 60 degrees F. That will largely enhance an adhesion and overall effect. |
| Question: | Is this enough for 1980 camaro floor? if i isolating the whole car (t tops) how many of that do i need |
| Answer: | Insulating the wheel wells, floorboards, firewall and doors would certainly decrease the high pitch noise but it won't totally cancel that. It appears that the source is tyres themselves. Sound deadening works more towards low frequency resonance elimination. Please note that all of our sound deadening materials are to be installed from the interior side only. |
| Question: | CHEN: Does this package come with enough to do my whole car? 2012 Hyundai Santa Fe ？How much package |
| Answer: | Unfortunately Noico 80 mil wont work in this case because the noise is caused by the fan movement and it is actually a flow of air that you get to hear and it can't be remedied with this material. |

User questions & answers
| Question: | Will this possibly deaden vibration if applied under a speaker grill which is vibrating |
| Answer: | I don't have the best smelling sense, but I do not believe the sound deadener has a strong smell. However, I'm using it a location that does not get hot. I cannot say whether added heat would cause the product to develop a stronger rubber type smell. |
| Question: | Will this product stick onto the stock tar (asphalt) sound deadener which OEM car manufacturers use |
| Answer: | 80 |
| Question: | Is there only 1 sheet of 32" x 54" in each box |

| Question: | I just read dynamats website and it states to use this product over the top of dynamat, can i use this instead of dynamat |
| Answer: | yes we make kits out of these and sell them |

User questions & answers
| Question: | Is one roll enough for a Jetta |
| Answer: | Yes one roll would be fine for just the floor. |
| Question: | Does this product have an odor |
| Answer: | No, i don't recall any odor at all. |
| Question: | Does it require some sort of glue or tape to fix it against the floor |
| Answer: | No, I did not need to use any tape, glue, or Velcro. It is firm enough to stay in place until you cover it with the original carpet. |
| Question: | From the Dynamat website it looks like you should first use Dynamat and then add Dynapad on top, in addition, for the floors. Have people done that |
| Answer: | Yes, based on how much sound deadening you want and how much you want to spend. I used this in multiple cars. The best approach is two layers of Dynamat and then one layer of Dynapad. Since each product works on different frequencies, you need at least one of each for best results |

User questions & answers
| Question: | I have a new, clean fuel tank that is tight but produces vibration noise at highway speeds, could this be applied to bottom or top of tank |
| Answer: | Yes. I put dynamat around a 4K generator in our rv. Sides,top and bottom. Did a great job not only deadening the noise but 2 years later, it’s still stuck on. Very impressed |
| Question: | Can it be used as a hoodliner |
| Answer: | Worked great, used it on my 1971 RoadRunner |
| Question: | Can this work on the inside of a sub box made out of aluminum, mdf is too thick for the space. Would half inch be thick enough? Thanks |
| Answer: | Yes, it will adhere to aluminum. It works best if you apply it in warm conditions. Make sure you Stick one edge down and then use a roller to apply the rest so you avoid trapping air bubbles. It will work on gentle curve but for hard corners, cut it and start a new sheet |
| Question: | does the thickness matter during the installation, as in can it be too thick I won't be able to put back the headliner |
| Answer: | We used this product in our 1957 Chevy and it was not too thick for the headliner. We used the 1/2 inch thickness |
