Load-bearing pillars and beams of a building, shall be borne by the entire fabric and the load is removed before it can be removed. In social life cannot noise emission source boundary noise measurement or measurement cannot reflect the degree of their influence on the noise-sensitive structures case, noise measurements at the sensitive structures of the window 1M likely to be affected. When society noise emission source boundary with noise-sensitive structures less than 1M, the indoor measurement of noise-sensitive structures, and corresponding limit values in the table 1 minus 10dB (a) as a basis for evaluation. Structure of fixed communication equipment room acoustic emission limits in the social life of noise sources in noise-sensitive structures within the case, noise when transmitted through the structure to a noise-sensitive buildings, and noise-sensitive buildings equivalent sound level shall not exceed table 2 and table 3 limits.
