Results: According to the results, 3.57% of the participants believed that mass media notification could be effective in controlling noise pollution (relatively high and positive); however, only 3.27% of the respondents utilized sound control methods (poor level of performance). Furthermore, 5.21% of the cases highlighted the effectiveness of the first floor of the buildings as a noise reduction factor for other blocks in a building complex (low level of awareness).
