The utility model relates to the technical field of building engineering, and disclose a housing construction stair step antiskid noise reduction device, including the bottom plate, the inside bottom end fixedly connected with the sound absorption layer of bottom plate, and the top end surface fixedly connected with the buffer layer of sound absorption layer, and the top end surface fixedly connected with the isolation layer of buffer layer, the top end surface fixedly connected with the water absorption layer of isolation layer, and the top end surface fixedly connected with the air permeable layer of water absorption layer. The utility model under the action of buffer layer, can to the user's tread impact force carry out certain buffer unloading, thereby reducing the impact force that stair bears, under the action of sound absorption layer simultaneously, can good absorption after tread friction sound and impact sound, and the material of sound absorption layer also has certain buffer unloading effect, this design under the cooperation of sound absorption layer and buffer layer can to the tread impact force of user's foot part produce buffer unloading, can effectively absorb the sound produced simultaneously, thereby reach the effect of noise reduction.
