How Does a Sound Dampening Board Work?
Sound can pass through a lightweight wall when the wall surface vibrates in response to voices, music, televisions, machinery or, machinery or speaker systems.
This board uses a layered construction to reduce that transmission:
- The magnesium oxide boards add mass and rigidity to the wall or ceiling.
- The polymer damping layer helps dissipate vibrational energy between the two rigid boards.
- The composite structure reduces resonance within the board.
- The dense surface helps limit airborne sound transmission to adjacent rooms.
Unlike decorative acoustic panels that mainly reduce echo inside a room, damping soundproof boards are installed as part of the wall or ceiling structure to help prevent sound from travelling from one space to another.
Key Features of Our Noise Dampening Panels
Composite Damping Structure
Two rigid magnesium oxide boards are bonded with a polymer damping material. This layered structure combines mass, stiffness and vibration damping in a single board.
Average 37 dB Sound Insulation
The board provides an average sound insulation value of 37 dB. Actual project performance will depend on the complete wall or ceiling assembly, framing, cavity insulation, joints, doors, windows and installation quality.
Multiple Thickness Options
Regular thicknesses include 15 mm, 16 mm, 18 mm and 20 mm. The appropriate thickness and model can be selected according to the noise source, available installation space and required acoustic performance.
Wall and Ceiling Installation
The boards can be incorporated into partition walls, shared walls and suspended ceiling structures. They are suitable for both new construction and interior renovation projects.
Fire-Resistant Construction
The magnesium oxide board construction provides fire-resistant performance and is suitable for commercial interiors with fire-safety requirements. Relevant test reports and project requirements should be confirmed before ordering.
Easy Cutting and Installation
Boards are supplied in standard 1220 × 2440 mm sheets and can be cut according to wall dimensions, ceiling layouts, openings and construction drawings.
Durable and Eco-Friendly
The board is non-toxic and designed for long-term indoor use. When properly installed under suitable conditions, it can provide a service life of more than 15 years.
Applications of Sound Dampening Boards
KTV Rooms and Karaoke Venues
Amplified music, vocals and subwoofers can transmit noise through walls and ceilings. Damping boards can be used as part of a complete sound insulation system to reduce disturbance between rooms and surrounding properties.
Bars and Entertainment Venues
Install the boards in partition walls and ceilings to help control music, conversation and equipment noise in bars, clubs, lounges and other entertainment spaces.
Hotels
Noise dampening panels can improve acoustic privacy between guest rooms, corridors, meeting rooms, restaurants and entertainment facilities.
Offices and Meeting Rooms
The boards help reduce speech transmission between conference rooms, executive offices, interview rooms, reception areas and other spaces requiring greater privacy.
Recording Studios and Music Rooms
Use the boards in walls and ceilings to reduce sound leakage from musical instruments, speakers and recording equipment. For professional studios, they should be combined with isolation components and interior acoustic treatment.
Home Theaters
Damping soundproof boards can help reduce the transmission of television, movie and speaker noise into bedrooms, neighboring rooms or adjacent properties.
Schools and Training Facilities
Suitable applications include music classrooms, lecture halls, rehearsal rooms, multimedia rooms and other areas where noise may interfere with nearby teaching spaces.
Hospitals and Consultation Rooms
The boards can be used in consultation rooms, rehabilitation areas and other facilities where speech privacy and a quieter indoor environment are required.

For spaces such as KTV rooms, bars, recording studios and home theaters, the two products are often used together. The damping board helps reduce sound leakage, while exposed acoustic panels help control echo and improve sound clarity inside the room.
Recommended Sound Insulation System
A single board cannot address every sound leakage path. For projects with high noise levels, especially music and low-frequency bass, the damping board should be incorporated into a complete acoustic construction.
A wall or ceiling system may include:
- Damping soundproof boards
- Acoustic wool or soundproof rock wool inside the cavity
- Resilient isolation clips or vibration isolation hangers
- Metal or timber framing
- Acoustic sealant around joints and penetrations
- Soundproof doors and treated ventilation openings
- Decorative acoustic panels inside the room
The final construction should be selected according to the building structure, noise source, target acoustic performance and local fire regulations.
How to Select the Right Board
Before requesting a quotation, provide the following project information:
- Application, such as KTV, hotel, office or home theater
- Wall or ceiling dimensions
- Type and intensity of the noise source
- Existing wall or ceiling structure
- Available construction thickness
- Required sound insulation target
- Fire-performance requirements
- Quantity and required sheet dimensions
- Need for standard sheets or custom cutting
Novabex can recommend an appropriate board thickness, model and supporting acoustic materials based on the project information.
Installation Considerations
Sound dampening boards should be installed on a stable wall or ceiling structure according to the project drawings.
For effective noise reduction:
- Cut panels accurately around doors, pipes, sockets and other openings.
- Avoid leaving open gaps between boards or around the perimeter.
- Seal joints and penetrations with compatible acoustic sealing materials.
- Prevent rigid connections that may create vibration bridges.
- Treat doors, windows, ventilation ducts and electrical boxes when they form part of the acoustic boundary.
- Confirm that the supporting structure can carry the board weight.
- Follow local fire and building requirements.
Installation quality has a significant effect on the final acoustic result. Even small unsealed gaps can allow sound to pass through the construction.
Frequently Asked Questions
