In modern building acoustic design and indoor noise control, structure-borne impact sound has always been one of the most prominent and challenging noise problems in residential and commercial buildings. Different from airborne noise that can be easily blocked by doors, windows and walls, impact sound generated by human footsteps, furniture dragging, equipment operation and indoor activities transmits directly through rigid floor structures. This kind of structural vibration noise decays slowly and spreads widely, easily causing continuous indoor noise disturbance and user complaints. For acoustic material manufacturers and construction engineering teams, traditional on-site inspection methods are easily affected by complex and changeable site conditions. Uncontrolled environmental interference leads to unstable test data, making it difficult to objectively compare the actual performance of different floor damping materials, structural designs and construction techniques. Without stable test support, project quality tends to fluctuate, and rework situations often occur during building acceptance, bringing extra cost pressure and reputation risks to construction enterprises.

Our custom impact sound insulation chamber is a professional structural acoustic test space developed in accordance with ISO 10140 series international acoustic standards and local building compliance specifications for Singapore and Southeast Asian markets. Adopting a mature double-layer cavity structure with an independent upper sound source room and lower receiving room, the chamber is equipped with a complete floating vibration isolation system and isolated enclosure structure, which can effectively isolate external structural vibration and stray sound interference, creating a balanced and stable test atmosphere. Different from airborne sound insulation chambers which focus on wall and window performance testing, this professional chamber is specially built for floor structural impact sound detection. A standard impact simulator is applied to stably simulate various daily floor vibration scenarios including walking, dragging and mechanical operation, supporting performance evaluation of different floor structures, floating floor systems and damping materials. All test procedures follow international engineering evaluation specifications, and the output data can be fully applied to product R&D iteration, construction scheme verification, engineering acceptance and official test report issuance.

Acoustic and damping material manufacturers can make full use of the chamber to carry out long-term and stable performance tests for floor cushions, damping mortar, vibration isolation coils and floating floor materials. By comparing test data from different material thicknesses, formulas and laying processes, enterprises can continuously optimize product structures and production techniques, reducing dependence on third-party testing resources and improving product competitiveness in the Southeast Asian market. Professional construction and acoustic engineering teams simulate diverse floor construction solutions in a standardized laboratory environment in advance, effectively eliminating potential structural sound risks before on-site construction, reducing rework rates and improving overall project delivery quality for apartments, hotels, schools, hospitals and various public buildings. For SAC-accredited testing institutions and university acoustic research laboratories, the chamber complements the missing structural sound testing capability, enriches the business categories of building acoustic inspection, and improves comprehensive industry service capacity and market influence.

We provide fully personalized and customized engineering solutions according to customers’ actual site conditions, space constraints and daily test demands, including integrated cavity structure design, professional vibration isolation systems, standard impact testing equipment and matched acoustic analysis software. All completed projects will pass multi-scene and repeated test verification to ensure stable acoustic performance of the laboratory. We provide long-term full-life-cycle technical support, including regular equipment calibration, sound field maintenance, system debugging and remote operation services. The chamber continuously delivers stable and standardized structural acoustic test conditions for building floor noise reduction renovation, new material performance verification and indoor acoustic environment optimization in Singapore and Southeast Asian construction markets, supporting the high-quality development of local green buildings and comfortable residential environments.
