Photo Report of Completed Work
The owner of a Audi A4 came to us with complaints of door panel buzz, highway hum, and weak mid-bass.
After inspection and a quick dB check, we proposed 4-door soundproofing using STP two-layer tech: Vibration vibration damping + acoustic/thermal decoupler.
We removed the trims, degreased the metal, checked for corrosion, and sealed service holes and speaker mounts.
Lightweight, non-bitumen stack—no hinge strain, OEM-clean reassembly.
Result: quieter cabin, tighter mid-bass, clearer vocals. Completed in 1 day.
Door Inspection
Having disassembled the door, we didn't see any sound-absorbing material. We clean it and degrease the surface.
Door Sound Proofing. Layer 1
- The first layer is STP Gold vibration insulation. It will remove vibrations, noise.
Door Sound Proofing. Layer 2.
- The second layer is StP Sonora to stop sound waves coming inside. Besides it stabilize temperature and acoustic comfort.
- To avoid any plastic rattles, we install StP Gold vibration damping there. On top applied Anti-Noise pack in each clips.
