The "Design Code for Computer Rooms" stipulates that the noise level in the main computer room, measured at the main operator's position with the computer system shut down, should be less than 68 dB(A). It also specifies that the main computer room should be located far from noise sources. When this cannot be avoided, sound absorption and insulation measures should be implemented.

Noise is an unwanted sound that can cause irritability, lethargy, and decreased work efficiency. Whenever possible, measures should be taken to reduce environmental noise levels.

The specific noise reduction measures to be considered are as follows:

1) The insulation layer installed on the floor absorbs 3dB of sound, and the raised floor provides 20dB of sound insulation.

2) The entire server room area is separated from each other by walls or glass partitions with a noise reduction capacity of 40dB (the "rigid" walls provide sound damping; the insulation layer provides sound absorption), and the glass partitions provide 15dB of sound insulation. This effectively prevents noise crosstalk between different areas.
