Abstract:
This thesis reports the assessment of the perceived effect of aircraft noise on Murtala
Muhammed International Airport and its environs. The study examines the noise
levels produced during aircrafts take-offs and landings and the effect of aircraft noise
on the occupants of the airport and its environs. It also assessed the coping strategies
adopted to aircraft noise by occupants of the airport and its environs. Furthermore, it
assessed the mitigative measures to aircraft noise at the airport. The study made use
of primary data which were obtained through the use of a sound level meter to
measure the level of aircraft noise produced at the airport and its environs.
Structured questionnaire was administered to the occupants of the airport and its
environs: to elicit information regarding the perceived effect of aircraft noise on the
respondents and on their adopted coping strategies. The survey also brings out
information on the measures in place to mitigate the effect of aircraft noise on the
occupants. Appropriate statistical techniques were used, which include descriptive
statistics, intrinsic nonlinear and binomial logit regression models, and Noise Gap
index (NGI). The study reveals that for every cubic increase in distance there is a
reduction in the noise level, for instance, for a cubic increase in distance the noise
level reduces by a factor of 0.004 in morning. It also unveils that aircraft noise level
impacts on the respondents‘ physiological and psychological well-beings, such that
there are significant positive correlations of (p=0) among the dependent and
independent variables. The study further shows that the coping strategies adopted
were effective except to close doors and windows, which revealed an insignificant pvalue
(.18). Finally, the study reveals that home noise insulation is the most effective
measure to mitigate aircraft noise in the airport and its environs. The study concluded
that despite the noise decay effect the occupants are significantly impacted by
viii
aircraft noise at the airport and its environs, however, home noise insulation are
capable of mitigating the noise produced by aircrafts either during take-off or
landing.
