A qualified floating floor system, primarily deployed in pump rooms and equipment plant rooms, delivers superior vibration isolation and acoustic insulation performance coupled with excellent structural stability, effectively attenuating mechanical vibrations and low-frequency structure-borne noise generated by operating equipment. The specialized floating floor assembly and its associated ancillary components are engineered with outstanding damping characteristics, efficiently suppressing floor slab resonance and vibrational friction induced by equipment operation, while preventing secondary noise generation during system performance—ensuring that the floor system itself does not introduce additional acoustic contamination. Employing a dedicated floating construction technique, the system decouples the equipment room floor slab from the building's primary structural substrate through a resilient separation layer, completely interrupting the rigid transmission path of vibrational energy. This approach fundamentally resolves the issue of equipment-induced vibration transmission in plant rooms, ensuring long-term acoustic comfort for the building's occupied spaces and safeguarding the structural integrity of equipment operations.
