## Questions & Answers

**Q: Does this reduce noise vibration from your vehicle or from the other vehicles around?**
A: I applied inner door skin metal.  It reduces road noise and noise when other vehicle passes, and when I close the door, I hear thud instead of tin can sound.

**Q: Is the exterior, metallic, coating conductive?**
A: No.  I just checked it with my VOM and it has zero conductivity.  Actually seems to be a great insulator.

**Q: Can you safely usethis to sound proof walls indoors? Thanks**
A: This is for car doors with metal doors not home walls with wood and dry wall.  There are different materials for home door sound isolation.

**Q: Can you glue a headliner directly to this product ?**
A: I wouldn't. The headliner will be uneven. It would be better to spray a foam on the product to get an even surface before you do that. But you can glue fabric, such as carpet to it with the proper adhesive. 3M 77 is my product of choice.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great and looks well made!
*by M***L on May 20, 2025*

Amazing product to keep the loud droning sound of the exhaust away from the inside cabin of the car !

### ⭐⭐⭐⭐⭐ similar to Killmat
*by W***N on September 30, 2022*

This CANOPUS Car Sound Deadening Mat is very similar to Killmat.I have used Noico mat for my 2010 Camry, Killmat for my 2015 Camry, and Amazon basic mat for My 2021 RAV4 Hybrid. I used up 36 sq ft Amazon basic mat for my 2021 RAV4. I needed more mat for my 2021 RAV4. So I ordered 18 sq ft of CANOPUS Car Sound Deadening Mat. I installed Canopus mat mainly on wheel well of my RAV4. All these mat suppose to reduce metal vibrations. They are probably all made in China. They are all similarly butyl based. None of them claim the percentage of other components. However, they are slightly different. The differences are mainly in adhesion when apply to the metal surface.They suppose to reduce car road noise. While car road noise are mainly generated by tire rubber slapping on the concrete or asphalt road. The sound frequency of road noise are mainly in 800Hz to 1200Hz. It wound be better if any of these manufacture to test what frequencies these mat are most effective. The markers of these mats are demonstrating effectiveness of these mats with a patch of mat on a gong. Applying a small piece of mat can eliminates the ring of gong, which are ringing at 300 and 3500 Hz. The hard part to reduce car road noise is that noise penetrating into car from every where, it hard to completely apply these sound deadening mat to every metal surface of car. The main penetrating point should be rear wheel well. That's why all SUVs are nosier and cars unless the price difference is five times and more. Applying sound deadening mats are very labor intensive, manufactures will not spend that much labor to apply these mats to their cars at the labor cost of $100 or so per hr. However, apply these mat only 25% metal surface will give maximum return of investment. The more will only give diminishing returns. 2010 and 2015 Toyota Camry comes with about 16 sq inch of similar sound deadening mat. While RAV4 dose not have any mat on the four doors, and only has a little on the 5th door. That's one of reasons makes Camry quieter stock than RAV4. After applying these mats, the doors on RAV4 as well as Camry feel much solid when closing with a solid thump, not an empty tin can sound any more.This Canopus mat are similar to Killmat when apply to the metal surface, are stickiest among these four mats. Noico mat is medium sticky. Amazon basic is least sticky. When handling these mat, disposable gloves are must for Canopus and Killmat, recommended for Noico and optional for Amazon basic. However, when applying these mats to the metal surface, a heat gun or hair dryer is must for Amazon basic, recommended for Noico, and optional for Canopus and Killmat. I warm the metal surface before applying the mat to the surface. I recommend a roller for application, especially for Amazon basic.I have put Canopus and Amazon basic mat in -20C freezer, both of them are still malleable and suppose to work in winter time. However, in -80C freezer, both of become brittle. In -80C, only metal and wood can still maintain most of characteristics of normal temperature anyway.I have made my RAV4 quieter by at least 3 db using these mats and other sound insulators.If I need to buy again, I would recommend Canopus and Killmat when they are priced similar.
