Understanding Sound Deadening Products

       So, there are many different types of sound deadeners, sound absorbers, noise barriers, and decouplers out there. Each and every one of these product types serves a specific task in reducing sound inside of a vehicle. 


1. Constrained Layer Damper Sound Deadeners

       Constrained Layer Damper (CLD) Sound Deadeners are essential in minimizing vibrations and rattles in your vehicle. Products like the original ResoNix CLD Squares, heavy-duty ResoNix Mega CLD Squares, or the lightweight ResoNix Lite CLD Rectangles are designed to dampen the vibrations of your car’s metal and plastic panels, significantly reducing the noise inside the cabin. They are particularly effective in dealing with low-frequency resonance noises, which are common in automotive environments.

2. Sound Absorbers     

       Sound Absorbers, such as ResoNix Fiber Mat 25 and 45, ResoNix Guardian, and ResoNix Lockout play a pivotal role in absorbing airborne sounds. These materials are typically made from fibrous or foam materials and are perfect for covering large surfaces like door panels and car ceilings. They work by absorbing sound waves, preventing them from reflecting back into or entering the cabin.

3. Decouplers

       Decouplers, like the ResoNix Fiber Mat 25 & 45, ResoNix CCF Decoupler 7S, ResoNIx CCF Decoupler 3S, and ResoNix CCF Decoupler 3F are designed to break the path of sound transmission. They create a physical separation between two surfaces, preventing noise from passing through. This is especially useful for areas where panels or parts of the car are in direct contact, leading to noise transmission.

4. Noise Barriers

       Noise Barriers, such as the ResoNix Barrier, are the final layer of defense against noise. These heavy, dense materials block external noises from entering the car. They are particularly effective against road and wind noise, making them an essential component for a sound deadening or sound proofing project.

Basic Install Guidelines For Sound Deadening Materials


1. Installing Constrained Layer Damper Sound Deadeners

To install CLD Sound Deadeners like ResoNix CLD Squares:

       .  Clean the surface where you’ll apply the deadener.

       .  Measure and cut the deadener to fit the panel.

       .  Peel off the backing and apply it to the car panel. Use a roller and apply light pressure, ensuring no air bubbles.


2. Installing Sound Absorbers

For installing Sound Absorbers such as ResoNix Fiber Mat:

       .  Clean and dry the area of application.

       .  Cut the absorber to size, taking the contours of the area into consideration.

       .  Secure it in place using the ResoNix Fiber Mat’s built-in peel-and-stick adhesive.


3. Installing Decouplers

For installing Sound Absorbers such as ResoNix Fiber Mat or ResoNix CCF Decoupler:

       .  Clean and dry the area of application

       .  Cut the decoupled to the required size.

       .  Place it between the two contact points to reduce buzzes, rattles, and noise transmission.


4. Installing Noise Barriers

To effectively install Noise Barriers like ResoNix Barrier:

       .  Locate areas with high external noise intrusion.

       .  Measure and cut the ResoNix Barrier material.

       .  Apply it appropriately, preferably with 100% coverage to create a solid barrier against external noise. 


       Conclusion: Sound deadening your car can significantly improve your driving experience.
