application areas
Different parts of a car require different soundproofing solutions

Car Door Soundproofing Installation
By installing vibration-damping sheets on both the interior and exterior of the car doors—and compressing them to achieve a vibration-suppressing effect—the transmission path of noise is effectively blocked. Simultaneously, the addition of sound-absorbing cotton within the plastic door liners serves to further absorb any residual noise.
- Noise levels can be reduced by 10–20 decibels while driving
- Enhancement of Audio Effects
- Enhancement of Audio Effects

Car Floor Soundproofing Installation
Effective soundproofing for a vehicle's floor requires the integrated application of a three-layer structure—comprising vibration damping, sound insulation, and sound absorption—while implementing corresponding measures tailored to different transmission paths.
- The comprehensive noise reduction level reaches 40% or even higher
- Effectively reduces low-frequency noise
- Reduce thermal conduction

Hood Soundproofing Installation
Methods for soundproofing an automobile's engine bay include installing sound-absorbing cotton, applying vibration-damping mats, replacing engine hood seals with noise-reducing versions, installing sound-insulating and heat-shielding firewalls, and performing acoustic treatments.
- Absorbs noise generated by the engine's operation
- Reducing Metal Sheet Vibration
- not only blocks noise, but also blocks heat

Car Trunk soundproofing installation
The car trunk is not a hermetically sealed cavity; rather, it constitutes a complex acoustic system formed collectively by metal panels, plastic liners, hollow structures, and gaps. Low-frequency vibrations are amplified through sheet metal resonance, generating standing waves and reverberation within the trunk compartment.
- Metal sheet vibration reduction enhances cabin quietness
- Absorbs tire noise, road noise, and wind noise
- Protecting the Car Trunk Structure

Wheel Soundproofing installation
Noise generated by tire-to-road friction, vibrations transmitted through the suspension system, and air turbulence within the wheel arches enters the cabin through components such as the wheel arches and fenders.
- Waterproof Sound-Absorbing Cotton
- Modifying Low-Frequency Resonance

More sound heat insulation solutions
NVH control technology has emerged as a key area of research in the fields of automotive manufacturing and modification; specifically, aftermarket soundproofing modifications primarily focus on optimizing noise propagation paths. GCI provides comprehensive vehicle soundproofing materials and solutions for brand-name clients.
