The purpose of this research was to measure the sound level in urban spaces. For this purpose, the gardens located in District 4 of Tehran municipality were selected as pilot research. The equivalent level was first measured by Decibel X software version 2020 and compared with the audio standard (OSHA-90 dBA). Then, by creating a stepped sound level, users' protest observations were recorded. The innovation of this research is in choosing the location and measurement method. The lowest and highest sound pressure levels were 65.68 and 77.15 dB. Most of the studied parks have lower average sound levels than NIOSH, OSHA and ACGIH standards. However, all items (except Lavizan Forest Park and Sahel) have a sound level higher than the standard of the Environmental Protection Agency. Also for users, the average time spent in a day is 2 hours. On the other hand, the highest percentage of user responses (88% and 87%) are related to the desired sound level (65-67 decibels) and the annoying limit (79-85 decibels), respectively, which shows that most users agree on these two ranges. have. On the other hand, the lowest agreement in the answers (37%) is related to the very desirable limit (less than 65 decibels). Sports facilities in the parks of Region 4 have a relative standard in terms of noise pollution.
