Zululkree Information and Control, Vol. How to cite this article. Besides, it proposes reviews available in literature and discusses noise annoyance exposure caused by transportation systems in an evolutive context. From the environmental point of view, airports cause serious problems to the population. Therefore, ant fuzzy logic system was abn in xbnt to establish a relationship between the percentage of people highly annoyed by adverse noise effects around the airport, Day Equivalent Sound Level L AeqD and Night Equivalent Sound Level L AeqN metric descriptors.

Fuzzy logic systems; Annoyance; Metrics; Aircraft noise. Airport noise presents a major environmental impact arising from aircrafts airport activities, being one of the most complex and difficult mitigation problems. However, acoustic comfort is assessed separately during the day and at night, because the noise adverse effects are different. Procedure, Rio de Janeiro. Journal of the Acoustical Society of America, Vol. Services on Demand Journal. Therefore, a fuzzy logic system was developed in order to establish a relationship between the percentage of people highly annoyed by adverse noise effects around the airport, Day Equivalent Sound Level LAeqD and Night Equivalent Sound Level LAeqN metric descriptors.
