Norm The results of the study, published in the table, show that the average rate of noise in the open space exceeds the norms by 9.5 dB, and as for the average noise level in a closed space, the lecture process in the classroom for example exceeds the permissible limit by 18 dB, and on the metropolitan escalator by 4 dB. It should be noted that an excess of noise levels in a closed space is mainly due to the frequency and acoustic effect of current conversations, and in the open space, the noise caused by the number of cars and movement of the main source is caused by movement.	cache/gs-1318.pdf	txt/gs-1318.txt
