Soundproof a Partition Wall

How to Soundproof a Partition Wall: A Comprehensive Guide

If you soundproof a partition wall, it can significantly improve the acoustic comfort of your living room or workspace. Soundproofing techniques can make a noticeable difference, whether you’re aiming to reduce noise from neighbouring rooms or create a quieter environment for concentration and privacy. In this guide, we’ll explore step-by-step methods for effectively soundproofing a partition wall.

How to Build a Soundproof Partition Wall?

If you want to soundproof a partition wall in Singapore, remember the following crucial steps suggested by LS Partition Wall Singapore.

1. Assessing the Existing Wall

Before diving into soundproofing measures, it’s crucial to assess the current state of your partition wall. Look for gaps, cracks, or holes that could allow sound to travel through. 

Check the material and thickness of the wall, as thicker walls with dense materials offer better sound insulation. Identifying weak points in the wall will guide your soundproofing efforts.

2. Seal Gaps and Cracks

One of the simplest yet most effective soundproofing techniques is sealing any gaps or cracks in the partition wall. Use acoustic sealant or caulk to fill in gaps around windows, doors, electrical outlets, and baseboards. 

Pay attention to seams where the wall meets the floor, ceiling, and adjacent walls. Sealing these openings prevents sound leakage and improves overall soundproofing performance.

3. Add Mass and Density

Increasing the partition wall’s mass and density is key to enhancing its soundproofing capabilities. Consider adding an extra layer of drywall to the existing wall, especially if it’s a single-layer wall. Alternatively, install soundproofing panels made of materials like mass-loaded vinyl (MLV) or acoustic foam. These materials absorb sound waves and prevent them from passing through the wall, reducing noise transmission significantly.

4. Use Soundproofing Insulation

Another effective method of improving soundproofing is installing soundproofing insulation within the wall cavity. Opt for insulation materials designed explicitly for soundproofing, such as fiberglass or rock wool. 

These materials absorb sound vibrations and prevent them from travelling through the wall. Ensure the insulation fills the entire cavity without gaps for optimal results.

5. Install Resilient Channels

Resilient channels are metal strips that decouple the drywall from the wall studs, reducing sound transmission. Install resilient channels on the wall studs before attaching drywall. 

When installing drywall over resilient channels, use soundproofing screws to reduce contact between the drywall and the channels. This setup prevents sound vibrations from transferring through the wall structure.

6. Opt for Double Glazing

If your partition wall includes windows or glass panels, upgrading to double glazing can significantly enhance soundproofing. Double glazing involves installing two layers of glass with a sealed air gap in between. This configuration provides better insulation against sound transmission than single-pane windows, effectively reducing noise from outside sources.

7. Use Soundproofing Paint

Specialized soundproofing paint can further enhance sound absorption on the wall surface. These paints contain sound-dampening additives that reduce noise reflections within the room. 

Apply multiple coats of soundproofing paint for optimal results. While not the sole solution, soundproofing paint complements other soundproofing measures and contributes to overall acoustic comfort.

8. Create an Air Gap

Consider creating an air gap between the existing wall and a new soundproofing layer for maximum soundproofing performance. This can be achieved by installing acoustic panels or soundproofing curtains on a separate frame in front of the partition wall. 

The air gap acts as a buffer zone that absorbs and diffuses sound waves before they reach the primary wall surface. This effect enhances soundproofing effectiveness.

9. Upgrade Door and Window Seals

In addition to sealing gaps and cracks in the partition wall, it is essential to pay attention to the seals around doors and windows. Poorly sealed doors and windows can be significant sources of sound leakage. 

Install weatherstripping or door sweeps around doors to create a tight seal when closed, preventing sound from escaping or entering through gaps. Similarly, upgrade window seals or use soundproofing curtains to minimize noise transmission through windows.

10. Address Sound Leaks Through Electrical Outlets

Electrical outlets and switches on partition walls can also contribute to sound leakage. Use foam gaskets or outlet insulating pads behind electrical outlet covers to seal gaps around outlets and switches. This simple yet effective measure helps prevent sound from traveling through electrical openings, enhancing partition wall soundproofing performance.

11. Consider Soundproofing Underlayment

If your partition wall includes flooring, consider using soundproofing underlayment beneath the flooring materials. Soundproofing underlayment is designed to absorb impact noise, such as footsteps or furniture movement, reducing sound transmission through floors. Choose underlayment materials with high Sound Transmission Class (STC) ratings for optimal soundproofing results.

12. Consult with a Professional

While many soundproofing techniques can be implemented as DIY projects, complex soundproofing challenges may require professional expertise. Consider consulting a qualified acoustic consultant or contractor for specialized soundproofing solutions tailored to your needs. A professional assessment can identify unique acoustic issues and recommend effective soundproofing strategies for optimal results.


If you want to soundproof a partition wall, you must combine sealing, adding mass, using specialized materials, and strategic construction techniques. By implementing these comprehensive soundproofing measures, you can create a quieter and more comfortable indoor environment free from unwanted noise and distractions. 

Remember to assess your specific soundproofing goals, budget constraints, and the level of sound insulation required for your space. With careful planning and execution, you can achieve superior soundproofing results and enjoy a peaceful living or working environment.
