Sound insulation solutions & installation procedures for KTVs and bars

Wall Sound Insulation Installation Guide

●Base Preparation:Evenly lay a layer of sound insulation felt on the surface of the wall to be treated. Secure it point-by-point with steel staples to ensure full adhesion with no gaps left between the felt and the wall.

●Vibration Reduction & Reinforcement:Install wall vibration dampers at 60cm intervals. Fasten the dampers to the wall using expansion screws that run through the dampers, to boost vibration-dampening efficacy.

●Main Keel Framing:First, install the main keels, spacing them 60cm apart to form a basic support framework.

●Sound Insulation Filling:Fully fill the gaps within the main keel frame with glass wool boards, ensuring no voids remain to maximize sound insulation capability.

●Secondary Keel Fixation:Attach the secondary keels by clamping them in place, with each keel spaced 40cm apart, to further refine the frame structure.

●Panel Sealing:Cover the exterior of the secondary keels with damping sound insulation panels, making sure the panels fit tightly against the framework.

●Final Sealing:Apply damping structural adhesive along all seams, including panel joints and keel connections, to achieve full-seal sound insulation.

Applicable Scenarios:KTVs, bars, party rooms, EDM rooms and other venues with high-frequency noise pollution

Sound Insulation Layer Thickness:Approximately 15cm

Floor Sound Insulation Installation Guide

●Base Vibration Reduction:Lay a full layer of vibration-dampening pads across the entire floor substrate, ensuring 100% coverage with no gaps, to establish a solid vibration-dampening foundation.

●Sound Insulation Overlay:Lay a layer of high-density sound insulation cotton flat on top of the vibration-dampening pads. Enhance sound insulation performance through this layered material design.

●Targeted Vibration Reduction:Place vibration-dampening bricks on the sound insulation cotton at 60cm intervals. Cut holes in the corresponding positions of the cotton with a utility knife, then fill the gaps within the vibration-dampening bricks with the cut cotton pieces.

●Panel Protection:Lay a layer of sound insulation boards over the vibration-dampening bricks and cotton to create a smooth intermediate layer.

●Secondary Sound Insulation:Add another layer of sound insulation felt on the surface of the sound insulation boards to further block noise transmission through the floor.

●Surface Finishing:Finally, pour a cement screed over the sound insulation felt. Once the cement has fully cured, lay the floor tiles to complete the overall floor sound insulation installation.

Applicable Scenarios:KTVs, bars, party rooms and EDM rooms located in close proximity to residential areas (requiring focused control over floor-borne noise transmission)

Sound Insulation Layer Thickness:Approximately 10cm

Ceiling Sound Insulation Installation Guide

●Top Substrate Preparation:Lay a layer of sound insulation felt on the wall sections adjacent to the ceiling and the ceiling substrate. Secure the felt with steel staples, ensuring tight adhesion to the substrate.

●Ceiling Vibration Reduction:Install ceiling vibration dampers at 60cm intervals. Fix the dampers to the overhead structural elements with expansion bolts to enhance the suspended vibration-dampening effect.

●Main Keel Erection:Install the main ceiling keels, spacing them 60cm apart to form a stable support frame for the ceiling.

●Sound Insulation Filling:Fill all gaps in the main keel frame with glass wool boards, ensuring the boards are fully packed with no empty spaces.

●Secondary Keel Fixation:Clamp the secondary keels in place, with each keel spaced 40cm apart, to refine the ceiling frame structure.

●Panel Sealing:Cover the underside of the secondary keels with damping sound insulation panels, ensuring the panels are flat and perfectly fitted to the frame.

●Final Sealing:Seal all seams—including panel joints and keel connection points—with damping structural adhesive to eliminate noise leakage.

Applicable Scenarios:KTVs, bars, party rooms, EDM rooms and other venues requiring effective control over overhead noise transmission.

Sound Insulation Layer Thickness:20cm or more
