Fabricated wave-shaped sound-absorbing suspended ceiling and construction method thereof

The invention discloses an assembly type wave-shaped sound-absorbing suspended ceiling and a construction method thereof. The suspended ceiling comprises a plurality of arc-shaped sound-absorbing bodies which are arranged in sequence; the arc-shaped sound absorption body is connected with a top beam or a floor slab through a stainless steel hanging piece; the arc-shaped sound absorption bodies comprise three types, namely, upper concave sound absorption bodies, large-diameter lower convex sound absorption bodies and small-diameter lower convex sound absorption bodies, and the two sides of each upper concave sound absorption body are adjacent to one large-diameter lower convex sound absorption body and one small-diameter lower convex sound absorption body respectively to form an integral wave shape; each arc-shaped sound absorption body comprises sound absorption cotton, moisture-proof cloth and an aluminum plate. The sound-absorbing and moisture-proof wall is good in moisture-proof and corrosion-proof effects
