PURPOSE: A block for a prefabricated soundproof booth are provided to be rapidly and easily assembled as a booth shape without an additional connecting member and improve the effects of soundproofing by efficiently preventing sounds from leaking out between the blocks. CONSTITUTION: A block for a prefabricated soundproof booth comprises a block body, a sound absorbing material(20), a perforated sound absorbing plate(30), and a sound insulation plate(40). The block body forms as a closure shape of which the inner surface is opened and comprises a connection protrusion(11) on the upper surface and a connection groove on the lower surface. The sound absorbing material is filled into the block body. The perforated sound absorbing plate covers the sound insulation plate by being attached to the inner surface of the block body and comprises a plurality of sound absorbing holes(31). The sound insulation plate is attached on both sides of the block body and blocks the leakage of the sound through the gaps between the main bodies. |
