Piu House Club & KTV

Project Overview

Project Overview

Piu House Club & KTV in Sri Petaling operates multiple private karaoke rooms within a commercial building that also houses other retail and dining tenants. Each KTV room runs high-powered sound systems with subwoofers, and guests frequently push volumes to peak levels during evening hours. The venue required a soundproofing solution that would prevent noise leakage to neighbouring tenants, contain sound between individual KTV rooms, and comply with local noise regulations — all without reducing usable floor area more than necessary.

Acoustic Challenges

KTV environments generate some of the most demanding acoustic conditions in commercial entertainment. Sound pressure levels inside each room can exceed 110 dB, with heavy bass content from subwoofers driving low-frequency energy through walls, floors, and ceilings. The challenge was twofold: first, preventing airborne sound from escaping through wall and ceiling partitions to adjacent commercial units; second, isolating each room from its neighbours so that guests in one room do not hear music from the next. Structure-borne vibration was a particular concern, as bass frequencies travel efficiently through rigid connections in steel and concrete framing, bypassing conventional insulation materials entirely.

Materials and Installation Approach

The wall assemblies received a layered treatment starting with SG-DM102 Vibration Damping Mat applied directly to the existing wall surfaces. This 2 mm dense mat, composed of fine iron powder, modified mineral powder, calcium carbonate, and PVC, adds mass loading and damps resonance in the substrate before any framing is attached.

SG-WD50 Wall Shock Dampers were then installed on the wall surfaces to support the metal stud framework. Each SG-WD50 uses a heavy-duty spiral spring combined with polymer damping rubber, achieving a natural frequency below 5 Hz. With a load capacity of 50 kg per unit, the dampers were distributed across the wall area to fully decouple the new acoustic wall assembly from the building structure. This decoupling is critical in KTV applications where subwoofer energy would otherwise travel through rigid stud connections directly into the building frame.

SG-E17 Composite Sound Insulation Boards were fixed to the decoupled stud framework. The SG-E17’s 8 + 2 + 8 mm construction — Calcium Silicate outer layers with an EPDM damping core — provides a 33 dB Weighted Sound Reduction Index. The boards were installed across all party walls and ceiling surfaces, and every joint was sealed with acoustic sealant to eliminate flanking paths. Pro370 Safe ‘n’ Silent was incorporated within the assembly for additional resilient isolation.

Results

After completion, Piu House achieved effective acoustic separation between all KTV rooms and between the venue and its neighbouring tenants. Guests could operate sound systems at full volume without generating complaints from adjacent businesses. The room-to-room isolation ensured that each private karaoke experience remained independent, which is essential for customer satisfaction in the KTV industry. The installation also satisfied local authority noise requirements for the commercial zone.
