Abstract:The influence of the wind rate (fresh air rate and exhaust air rate) of the main air port on the noise spreading from inside to outside in large-scale all-around hotel was discussed. If the wind rate was excessive, the noise of this side would go beyond the standard rate, thus the amount of the fresh air should be restrained. To ensure the noise satisfy the needs of the standard rate, the total wind rate of the main air port, less than 550000 m3/h (S=77 m2) and about 25% of the total wind rate (fresh air rate and exhaust air rate) of the present whole-building air condition, was recommended.
