2. Description of the Related Art In general, sound-insulated floors directly attached are constructed by a method of directly attaching flooring materials to a floor surface of a building, and are mainly intended to reduce lightweight floor impact noise. The impact force applied to the floor is alleviated, and the impact force transmitted downstairs is reduced. Wood-based sound-insulating flooring materials used in the construction of this type of directly attached sound-insulating floors reduce the bending rigidity by providing grooves in the base plate, and the overall flooring by stacking cushioning materials Measures such as reducing the spring constant per unit area, and laminating vibration damping materials to attenuate vibrations generated by impacts provide a shock absorbing effect and improve soundproofing performance.
