Factors to Consider When Choosing an Automotive Sound Deadening Material
As you can see, not all sound deadeners are made equal. Some outperform others in certain soundproofing properties. Thus, it’s important to consider certain factors when making a choice. Here’re the factors you should consider when choosing a sound deadening material for your car:
Thickness and Density
A highly dense and thick material will offer better soundproofing than a thinner, less dense material. Basically, the thickness of a sound deadener is measured in mils. The higher the mil value, the thicker the material. On the other hand, the density of a sound deadener is measured in pounds per cubic feet. The higher the value in pounds per cubic feet, the higher the density.
Another factor to consider is the size of the material. A larger material will cover a larger area whereas a smaller sized material will cover a small area. If you’re soundproofing areas such as the roof and hood, then you definitely need a larger material. A smaller sized material is ideal for soundproofing surfaces such as the doors and firewall.
You should also consider the weight of the material. For instance, a heavy sound deadener might weigh down your car doors and even add to the weight of your car if applied to more surfaces. The heavier your car, the more the fuel it will consume. Thus, a lighter material will not affect the fuel consumption of your car. Basically, the weight of a sound deadener is denoted in pounds. The higher the value in pounds, the heavier the material.
Ease of Installation
Another crucial factor to consider is the ease of installing the material. The best material is the one which is easy to work with. It should be easy to cut the material and shape it to match the area you want to install it. Besides, it should be flexible enough if you’re planning to install it around contours. Also, it’ll help if the material has some form of indication on whether you’ve installed it properly.
Tolerance to Extreme Temperatures
The tolerance of the material to extreme temperatures matters a lot when it comes to sound deadening materials. The car panels are exposed to heat from the sun, engine, and exhaust. Thus, the best material to use is the one that can tolerate high heat levels. It shouldn’t melt away during a hot summer day or when the engine heats up. Besides, it shouldn’t freeze or come off during a cold winter day.
The last thing you’d want in your car is installing a material that will add a bad odor. Thus, consider an odorless material, especially if you’re allergic to strong smells. Although the smell of some materials goes away a few days after installation, others may linger for a longer period. Thus, you’d rather go for an odorless material.
The adhesiveness of the material matters a lot on how reliable it will be. The best material is the one that adheres tightly to the area being insulated. It’ll help if the material comes with a self-adhesive surface. Such a material will save you from the hassle of applying glue. Besides, a material that adheres in place without heating it with a heat gun will also be easier to work with.
Method of Sound Insulation
You should also consider the method of sound insulation of the material you’re choosing. Some materials work by absorbing noise while others work by soundproofing. If most of the noise in your car cabin comes from outside the car, then you should choose a material that works by soundproofing to minimize outside noise. On the other hand, if most of the noise is coming from within the car such as rattling car panels, then you should choose a material that absorbs noise. You can as well combine the sound insulators in two layers.
The thermal insulation ability of the material is an added advantage. A sound deadener that doubles up as a thermal insulator would make your car cabin soundproof while still keeping it more comfortable by keeping heat away during summer. Besides, it will keep the car cabin warm during winter but retaining heat within the cabin. Consequently, you won’t have to turn on the air conditioner throughout, thereby saving on fuel.
Soundproofing your car can make all the difference in enhancing your car music experience. By choosing the right sound deadener for your car, you’ll enhance its acoustics by reducing road noise, rattling, vibrations, engine noise, and noise from loud exhausts among other unwanted noise. We hope that our review and buying guide will assist you in finding the right sound insulator for your car. After all, we’ve only reviewed the best automotive sound deadening material available today.
