Aircraft Noise and its Effects on Blood Pressure and Heart Rate at Mehrabad Airport Employees

Background: Sound is an inevitable part of everyday life these days. Hypertension is the most significant preventible risk of immature death all around the world. The main purpose of this study is to answer this question: Does aircraft noise affect blood pressure and heart rate? Methods: To achieve this objective, 100 personnel from the airport were selected. Additionally, 100 personnel were selected for the control group. In this case-control study the B&K dosimeter  model 4444 was used to record noise in a long time duration (8 hours) Blood pressure and heart rates were measured before and after their shift and during their work shift by connecting a dosimeter device to their body and recording noise exposure. SPSS V.22 software was used for statistical analysis. Results: Analyses showed that the average noise intensity in the experimental group was 87.84 ± 2.76, and in the control group, it was 70.01 ± 4.01chr('39')s. Compared with the control group, mean differences between systolic (P <0/001) and diastolic blood pressure (P=0.047) was significant, while the mean differences in heart rate after the shift not have a significant (P> 0.05). Conclusions: research indicates that unacceptable noise could be a hazardous agent for hypertension. It is suggested that monitoring blood pressure, training workers, and periodic examination to be practiced to decrease blood pressure.
