Soundproofing Your Singapore Home: Practical Solutions

Soundproofing Solutions for Singapore Homes Living in close proximity to neighbors means noise is a common concern. While perfect soundproofing is nearly impossible in HDB and condo construction, several renovation choices can significantly reduce noise transmission. Types of Noise Airborne noise travels through the air: conversations, TV, music, and barking dogs. This type of noise can be reduced with denser walls, sealed gaps, and insulation. Impact noise travels through the building structure: footsteps from above, furniture dragging, and children jumping. This is harder to block because the vibrations travel through concrete. Walls Standard HDB partition walls are 75-100mm thick and provide minimal sound insulation. For rooms where noise is a concern, consider adding a layer of acoustic insulation. A simple upgrade is adding a layer of mass-loaded vinyl (MLV) behind a new layer of plasterboard. This adds about 25mm to the wall thickness but significantly reduces sound transmission. Cost: $15-25 per sqft. For maximum isolation, build a decoupled wall using resilient channels that separate the new plasterboard from the existing wall. This breaks the vibration path. Cost: $25-40 per sqft. Doors Solid core doors block significantly more noise than hollow core doors. A solid timber or solid core HDF door reduces sound transmission by 25-30 decibels compared to 15-20 for a hollow door. Add acoustic seals around the door frame and a door sweep at the bottom to close gaps. Even a 3mm gap under a door allows considerable noise through. Flooring Carpet and underlay provide the best noise reduction for impact noise. However, carpet is not practical for most Singapore homes due to humidity and dust concerns. Vinyl flooring with acoustic underlay (3-5mm foam or cork) is a practical alternative. It reduces impact noise by 15-20 decibels compared to tiles directly on screed. Rubber mat underlayment beneath tiles or vinyl adds impact noise insulation without adding significant height. Cost: $3-8 per sqft. Windows Thicker glass reduces noise. Standard windows use 5mm glass. Upgrading to 10mm laminated glass can reduce external noise by 30-35 decibels. Double glazed windows with an air gap between two glass panes provide the best noise insulation. Cost: $80-150 per sqft. Most effective for traffic and construction noise. Ensure window frames are properly sealed. Worn rubber seals should be replaced. Sliding windows generally seal less effectively than casement (swing-open) windows. Ceiling Impact noise from the unit above (footsteps, furniture) travels through the concrete slab. A false ceiling with acoustic insulation (rockwool or fibreglass batts) between the existing ceiling and the new plasterboard helps absorb some of this noise. This solution reduces airborne noise effectively but has limited impact on heavy footsteps which transmit through the structural concrete.
