  • Patent number: 10269338
    Abstract: A hard panel of wall and floor structures for reducing floor impact sound according to example embodiments includes patterned layer having different density and elastic modulus form a base layer. A transmission path of an acoustic wave may be changed in a lateral direction by passing the patterned layer and the sound energy is dissipated by the refection, refraction, and cancellation of the acoustic wave. Thus, a noise is reduced. The hard panel of the wall and floor structures according to example embodiments is effectively reduces the light and heavy impact sounds. In addition, the hard panel is formed by at least one patterned layer to refract and reflect the acoustic wave such that the floor noise may be effectively dissipated. The hard panel is further includes the sound absorbing material to absorb the noise passing through the hard panel such that the floor noise can be effectively reduced.
