The invention relates to a wall proximate matter, particularly to a sound attenuation wall proximate matter structure. At least one racket-shaped bulged clamping strip (4) is arranged on the front surface of a square tube (9); bulged C-shaped grooves (5) are formed in the back surfaces of face sound attenuation plates (6); a bulged surface (1) on one side of a plurality of back proximate matters is clamped with a groove (8) of the adjacent back proximate matter; the racket-shaped bulged clamping strip of each back proximate matter is clamped with the C-shaped groove of each face sound attenuation plate; two bulged angles (14) are arranged on one side of a plate body (13) of each face sound attenuation plate; a single bulged angle (15) is arranged on the other side of the plate body; the two bulged angles on one side of the plate body are clamped on the single bulged angle on the other side of the adjacent plate body; a sponge strip (3) is arranged in a cavity between every two racket-shaped bulged clamping strips. According to the invention, a gap between every two face sound attenuation plates is utilized to absorb low-frequency noise, and the sponge strips absorb sound entering the every two racket-shaped bulged clamping strips.
