Noise complaints in residential buildings, hotels, schools and healthcare facilities often come from structure-borne impact sound, rather than airborne noise. Footsteps, furniture movement and other impacts travel through floor slabs to the space below. This kind of sound is difficult to control with ordinary wall insulation materials. The impact sound insulation chamber serves as a dedicated acoustic laboratory to assess how floor assemblies, floating floor layers and vibration isolation constructions reduce impact sound transmission, delivering a stable test environment for building acoustic research and compliance testing.

The chamber adopts a dual-room floating structure. The upper room works as the source room, where a standard tapping machine generates controlled impact excitation. The lower receiving room is separated structurally to minimise flanking transmission. The design follows widely recognised international standards for building acoustics. Unlike on-site measurements which are affected by surrounding vibration and ambient noise, laboratory testing inside this chamber maintains consistent conditions, allowing manufacturers and testing bodies to compare different construction solutions repeatedly during product development. It helps teams identify possible acoustic issues before building completion.

This facility is widely used by manufacturers of floor underlayment, precast concrete slabs and integrated floor heating systems. For residential acoustic underlay development, engineers can test different material formulations and thicknesses to observe variations in impact sound pressure levels. For schools and healthcare developments, component samples are tested here to support acoustic design reviews and project compliance checks. As prefabricated construction grows in Southeast Asia, the chamber also supports regular acoustic verification for modular floor systems.

We offer customised chamber solutions tailored to site constraints, applicable test standards and sample dimensions. Our scope covers layout design, floating isolation system construction, acoustic commissioning and ongoing calibration support. It can also be integrated with air-borne sound insulation chambers, reverberation rooms and other acoustic labs to form a complete acoustic testing suite.

A comfortable quiet environment starts with reliable floor acoustic design. The impact sound insulation chamber turns invisible structure-borne sound into comparable measurement data, supporting acoustic designers and material developers to refine construction details, and deliver better acoustic comfort for occupants.
