[0002] Floor sound insulation material refers to a material, component, or structure that isolates, blocks, and separates impact noise and airborne noise from building floors. The sound insulation pads used in floor sound insulation materials must be pre-installed within the slab of the upper floor to absorb or reduce impact waves generated when upper-floor residents use their rooms; otherwise, the impact waves from the upper-floor residents will transmit noise not only through the floor but also through the walls to the lower-floor residents.
