This invention relates to an indoor soundproof panel, being characterized by forming a plural through holes formed at given intervals bilaterally and vertically in a metal plate, bonding fixedly a sound absorbing material, where plural resonance spaces are formed so that the peak of each space may be located in the center thereof to the center of each through hole, with the reverse side of the metal plate and providing a tape layer on the reverse side of the sound absorbing material. The indoor soundproof panel under this invention lets any indoor noise to be primarily reflected irregularly from the surface of the metal plate, and secondly, the noise within the resonance space to be damped and absorbed therein. Therefore, it has an excellent effect on any indoor soundproofing. Its structure is so simple with a lightweight that it can be easily installed as a very useful invention. |
