Station building waiting space suspended ceiling three-dimensional composite sound absorption and noise reduction structure

The utility model discloses a station building waiting space suspended ceiling three-dimensional composite sound absorption and noise reduction structure which comprises a wave-shaped unit suspended ceiling, and the wave-shaped unit suspended ceiling comprises an aluminum circular tube curtain suspended ceiling, a horizontal keel, an elastic suspender keel and an integral type multi-layer composite sound absorption structure installed on the elastic suspender keel. The aluminum circular tube curtain suspended ceiling is installed at the bottom of the elastic suspender keel through connecting bolts. By reasonably designing the surface shape and the space structure of the suspended ceiling, a large flat rectangular space is divided into small-size aggregated acoustic spaces, so that multiple scattering of sound waves can be realized, and the sound absorption effect is further improved; sound wave energy is absorbed through the special surface performance and gaps of the suspended ceiling microporous aluminum ro
