Specifically, the 40×40 channel steel square tube frame is precisely installed according to design requirements, ensuring levelness and verticality, and then secured to the wall base layer by welding or bolts. Finally, the surface layer support frame 2 is installed on the wall support frame 1 and leveling and verticality are corrected. The cavity formed by the surface layer support frame 2 can also be prepared. Water glass wool wrapped in dense glass cloth is filled into the cavity to ensure uniform filling and no gaps.

[0029] The sound absorbing panel installation step S2 is to install the surface layer sound absorbing panel on the surface layer support frame.

[0030] Specifically, a 15mm curved micro-particle sound-absorbing board can be used as the surface sound-absorbing board 3, fixed to the surface support frame 2, and connected with an angle steel 7 to ensure that the board surface is flat, the curved surface transition is natural, and it is coordinated with the overall wall surface. In the hidden door installation step S3, the hidden door body is installed on the wall support frame at the door opening of the surface support frame.
