9 Purpose of the study To evaluate the association between aircraft noise pollution exposure and the prevalence of headache, hypertension, insomnia, stress, hearing problems, and colitis in working place near Abu Dhabi International Airport The impact of aircraft noise on the health of the employees who are working in areas adjacent to the airports is not addressed

10 A revealed preference (RP) face-to-face interview survey was conducted during the months of February and March, 2015 to collect primary data on the impact of aircraft noise pollution on the health of the employees working adjacent to Abu Dhabi Airport. Collect data on the potential negative effects that aircraft noise can have on the health of workers Explore coping strategies to mitigate this impact. Includes different socio-demographic questions to provide data for a series of statistical tests. A total of 1,995 workers in both areas (995 near the airport and 1,000 far from the airport) were interviewed and completed the questionnaire.

11 Study Area: Near the airport: within a 25-km radius of Abu Dhabi Airport Far from the airport: outside a 25-km radius of Abu Dhabi Airport

15 Comparing the socio-economic characteristics between the two samples No significant differences between the two samples X 2 -value P-value Gender Nationality Age Income Occupation Number of persons in household Number of children under 12 years old

16 To examine the impact of aircraft noise on the health of the exposed group, a chi-square test was conducted to determine if there is any statistical significant difference between the exposed and the control groups. No impact on workers health as a result of aircraft noise pollution X 2 -value P-value No disturbance (can tolerate) General disturbance (irritation) Headache Hypertension Loss of sleep/insomnia Stress Hearing problems Colitis

17 Binomial logit models for predicting the impact of aircraft noise pollution on employees health based on employees socioeconomic characteristics β Std. Error Wald df Sig. Exp(β) Intercept Nationality Age Gender Income Occupation Number of persons in household Number of children less than 12 years old Time worked adjacent to the airport

18 The results showed no association between aircraft noise pollution exposure and the prevalence of headache, hypertension, insomnia, stress, hearing problems, and colitis. There are no significant differences in the health between employees working in areas adjacent to the airport and other employees working far from the airport.

19 Many occupational places in Abu Dhabi are designed and built based on specifications to minimize the impact of external noise on the employees.
