Background: Noise is one of the harmful factors of industrial environments that may cause defect such as hearing defects, high blood pressure, irritation, sleep disturbances, increased respiratory rate and oxygen consumption. The residents and personnel working in industries around Mehrabad airport continuously exposed to noise pollution caused by the traffic of passenger, war and training airplanes. The aim of this research was to evaluate the noise exposure in personnel of various industrial and administrative units of the Aerospace university research complex next to Mehrabad airport. Methods: In this research due to variations in air transportation system and changing the number of flights during the day eight-hour personal dosimetry in a one-week period and octa and band analysis in wind tunnel room was performed. Sound level meter (CEL-440) and dosimeters (CEL 281 & 282) were used as measurement equipment. Obtained data was compared with the standards of Iranian Occupational Health Technical Committee and American Conference of Governmental Industrial Hygienists (ACGIH-2005). Findings: Values obtained from noise dosimetry were as follows; build hall 96.7(dB), welding 99.6(dB), aerodynamic 94 (dB), modeling 99.6(dB), shielding 95(dB), administrative building 77 (dB), planning office 77 (dB) and security station 76 dB. The result of octave-band analysis on the frequencies of 125, 250, 500, 1000, 2000, 4000 and 8000(Hz) were 93.1, 95.5, 93.1, 90.2, 85.5, 77.6 and 68.46(dB) respectively. Conclusion: The results of this study indicated that noise rate was above the standard rate (ACGIH-2005) and that was recommended by the country's occupational health technical committee, so, in order to prevent the consequences of noise exposure recommendations were presented  Key word: Noise pollution, Noise measurement, Noise dosimetry, Mehrabad Airport
