Introduction and Purpose: Noise pollution is one of the important environmental problems that has been on a growing trend in the recent years. This study was conducted to evaluate the level of noise pollution in Omidiyeh city, Iran. Methods: Testo 815 sound level meter was employed to quantify the sound pressure level (SPL). The measurements were conducted during 7-9 am, 12- 14 am, and 19-21 pm, at three locations (one station in each of commercial, residential, and commercial-residential areas), and the results were compared with the standard level of noise pollution.
