Sound Deadening Material for Cars – 5 Reasons You Should Install It

Soundproofing your car is a crucial part of upgrading your car stereo system. Soundproofing a car involves installing sound deadening materials such as soundproofing panels, sound deadening insulation foam, and sound deadening mats. Sound deadening works by dampening noise and reducing car panel vibrations. In this article, we’ll show you the importance of installing sound deadening material for cars.

What Is Automotive Sound Deadening and How Does It Work?

You might be struggling to listen to your car music due to excessive engine noise, road noise, vibrating car panels, or noise from other cars. If you’re facing such problems, you may try to turn up the volume of your car stereo high. However, listening to extremely loud music may feel exhausting. So what’s the best solution to this problem? Installing sound deadening insulation in your car is the best solution.

Essentially, sound dampening materials are attached to the interior of a car to soundproof it from unwanted noise and vibrations. They’re typically installed on the firewall, floor, roof, trunk, and door panels.

Sound deadening materials for cars are available in several types including:

• Automotive sound deadening mats- They’re malleable and fitted by sticking them on the door panels or the floor to absorb vibrations.
• Automotive sound deadening insulation- Insulation sheets are available in various thicknesses. You can cut them to size to fit on the interior of your car. They’re ideal for absorbing noise waves. Thus, they’re perfect for reducing engine noise and road noise.
• Car sound dampening acoustic foam- Insulation foam for cars is ideal for sound deadening the wheel well, firewall, and floorboards. It works by absorbing noise.

Benefits and Importance of Installing Sound Deadening Material for Cars

Installing automotive sound damping material in your car is a cost-effective way of upgrading the performance of your car audio system. Here are the reasons why you should install sound deadening in your car:

1. Reduces Vibrations and Rattling

Sound deadening mats, also known as sound dampener mats, and acoustic foam are great for reducing vibrations and rattling of car panels. If you have a powerful subwoofer or are driving along rough roads, door panels and other car panels can rattle. The rattling and vibrations will reduce the quality of your car sound system. Installing sound deadener mats will reduce rattling noise for a better listening experience.

2. Reduces Noise Transmission

You can apply sound dampening material on the door panel. The material increases the weight of the door. As a result, there’s reduced transfer of exterior noise into the car cabin. Also, sound deadening seals larger openings within the doors. Thus, there’s reduced noise transmission. Consequently, you’ll enjoy better bass performance, especially when using powerful car speakers and subwoofers.

3. Reduces Background Noise

You can reduce the noise in your car cabin by applying sound damping material to the floor, roof, cargo area or trunk, and doors. Reducing background noise makes it possible to hear more details in an audio recording. Also, reduced background noise improves the clarity of Bluetooth phone calls.

4. Reduces Noise from the Tires and Exhaust

If you have a loud exhaust system or tires that make loud noise, installing car sound insulation material will make the cabin noisy. As a result, you’ll find it hard to listen to music or make Bluetooth calls in your car. Installing automotive sound deadening materials can help in absorbing tire and exhaust noise. Consequently, your car will have a better acoustic environment for listening to podcasts, music, or making hands-free phone calls.

5. Increases Comfort

Some car sound dampening materials comprise a layer of butyl rubber, flexible aluminum sheet, and foam. The combination of these materials reduces noise while insulating the cabin against heat. Such automotive insulation materials are especially effective for preventing heat transfer from the engine, exhaust, and the exterior into the cabin. Consequently, it reduces the need to turn up the AC. That way, the insulation keeps heat inside the cabin during winter and away from the cabin during summer.

Does Sound Deadening Material for Cars Improve Bass?

Adding sound deadening sheets made of dense asphalt or butyl-based materials on the door panels, firewall, and floor increase the mass of the panels. Consequently, they reduce panel vibrations. Besides, sound deadeners seal gaps and passages where sound waves may pass through. As a result, there’s lower transmission of sound waves into the cabin.

Installing automotive sound-deadening material improves the sound pressure level score in your car. Also, they reduce road noise and vibrations that may get into the cabin. Consequently, you’ll experience better bass performance of your car audio system.

Will Automotive Sound Deadening Make My Car Heavy?

To effectively soundproof your car, you’ll need to add a significant amount of sound deadening material. However, that means you’ll add to the mass of the car. If you apply sound deadening all over the car panels, you’ll increase the weight of your car significantly. Thus, the best solution is to create a balance between soundproofing and the weight of your car. Preferably, only soundproof important parts of your car such as the door panels, firewall, floor, and trunk.

Final Thoughts

Installing sound deadening material for cars makes the cabin quieter by reducing engine noise, rattling and vibrations of panels, and road noise. Thus, you’ll enjoy a better listening environment in the cabin. Also, some insulation materials reduce heat transfer for a more comfortable cabin. Although sound deadening your car will cost you some money, it’s worth the added quietness and comfort. Thus, consider sound deadening insulation in your next car audio upgrade project.
