Why Should Vibration Damping Panels Be Applied in Strips?
4 Answers
Applying vibration damping panels in strips can achieve better noise reduction effects. Here are the detailed introductions of vibration damping panels: 1. Installation method: First, remove the four-door trim panels and clean the dirt inside. Then apply the vibration damping panels on the metal sheet layer and press them firmly. Cover with a layer of sound insulation cotton, and apply the vibration damping panels on the trim panel layer as a whole. The door trim panels can be covered with sound insulation cotton or applied on the trim panel layer. Finally, reinstall the four-door trim panels. 2. Function: The function of vibration damping panels is to eliminate low-frequency vibration and noise bands caused by the metal sheet during idling or driving. The function of sound absorption cotton is to absorb medium and high-frequency noise bands generated externally or internally during driving.
I used to work on cars a lot, and applying vibration damping sheets in strips makes absolute sense. If you apply them in one whole piece, the curvature of the car body makes it hard for the material to adhere properly, and too many air bubbles will render the soundproofing ineffective. Strips allow flexible adhesion to every corner without wrinkles. I once tried laying down a whole piece directly, and it peeled off the next day, forcing me to redo it. This method also saves material, reducing costs. For vehicles, vibration points aren’t fixed, so strip distribution can absorb more energy, ensuring more stable noise reduction. The key is to leave gaps for material expansion and contraction to prevent cracking from thermal changes. Generally, strips about 10 cm wide work best. Take your time when applying them, pressing each strip firmly, and you’ll solve most of the noise issues.
I've personally applied sound deadening mats and found that strips are easier to handle. The inner door panels are uneven, making it difficult to align whole pieces and wasting adhesive. Cutting them into strips and applying them one by one ensures a more secure fit. This method saves about 20% of materials, making it both eco-friendly and cost-effective. From an insulation perspective, the gaps between strips allow for air circulation, keeping the car comfortable even on hot days without AC. Online tutorials recommend this design to avoid material buildup that can create resonance points. After application, the annoying humming noise on highways was significantly reduced—totally worth it. DIY enthusiasts might want to try using a cutter for assistance—it's both convenient and efficient.
Physically, the strip application disperses pressure and vibrations. A full-board application tends to form a rigid surface, transmitting noise; whereas dividing into small strip units can buffer impact forces and reduce hot spot resonance. Each strip, 10 to 15 cm wide, covers like a net, absorbing energy evenly. The spaced gaps allow the material to stretch freely, preventing cracks and enhancing durability. This design significantly improves comfort during high-speed vibrations. The clever design optimizes sound insulation effects.
