PURPOSE: A soundproof structure is provided to efficiently reduce a crashing sound and noise, and to prevent the weight of the structure and construction costs from being increased. CONSTITUTION: A soundproof structure comprises a lower slab(10), a first shock absorber(20), a second shock absorber(30), a third shock absorber(22), and an upper finishing layer(40). The first shock absorber is installed in the top of the lower slab. The second shock absorber is installed in the top of the first shock absorber, and has one or more insertion spaces(32). The third shock absorber is installed in the insertion spaces of the second shock absorber, and has a lower dynamic modulus of elasticity than the second shock absorber. The upper finishing layer is installed in the top of the second shock absorber. |
