The invention belongs to the technical field of floors, and particularly relates to an environment-friendly silencing floor. The silencing floor comprises an upper base plate and a lower base plate, the upper base plate is clamped to a clamping groove in the lower base plate, and a dehumidification module is arranged on the upper base plate; the dehumidification module comprises a heating unit, anair cavity, an air pipe, a water collecting tank, a lantern ring and ceramic collecting tanks; the heating unit is located below the ceramic collecting tank; the air cavity is formed above the upperbase plate, and the air cavity is communicated with an annular cavity in the lantern ring; the lantern ring sleeves the outer rings of the ceramic collecting tanks, and the two ceramic collecting tanks are symmetrically arranged; the tops of the ceramic collecting tanks are communicated with the outside by means of through holes formed in the upper base plate, and the lower portion of the annularcavity in the lantern ring is communicated with the inclined water collecting tank through the air pipe; the other end of the water collecting tank is communicated with the interiors of the ceramic collecting tanks. The silencing floor is simple in structure and convenient to install, and silencing and prolonging of the service life of the floor are achieved through the cooperation of the dehumidification module and a silencing layer.
