Study of the road traffic noise in Erzurum-Turkey Mahir Gökdag
Abstract Road traffic noise affects a large number of people, especially in urban areas and is generally a major source of complaints. This paper refers to a study of the problem of traffic noise on roads which have been transformed into streets in the city of Erzurum. Noise levels are measured and the impacts suffered by the community are documented. Manual noise measurements were made along 12 streets exploring sources of maximum noise levels. Noise from different types of vehicles driven in a realistic way in inner city traffic was measured. The results from the measurements showed that, of 750 measured events, approximately 5% of the vehicles exceeded 70 dB(A) and less than 2% exceeded 80 dB(A) maximum noise level. In summary, the result showed that the most important vehicle component as regards the maximum noise level in inner city traffic was a medium-weight vehicle. Among the higher noise levels measured (>80 dB(A)) this type of vehicle was dominant. Keywords: Traffic noise, Noise pollution, Vehicle noise, Sound level, Environment, Noise
Introduction In modern times, noise is recognized as a serious health problem. Road traffic is the most significant source in the city and is one of the most pervasive types of noise pollution and generally considered more intrusive than other types of noise such as industrial noise, airport and community noise. The main urban transport problems include street injuries and fatalities, congestion, inadequate public transport and pollution. Air and noise pollution are the two undesirable impacts of the vehicular traffic and are especially important in urban areas [1]. Noise pollution caused by traffic has become a big social problem and will become more serious and widespread. Over a number of years, investigations in different countries have shown that noise affects different activities and causes sleep disturbance and poorer life quality [2,3]. Noise pollution has a detrimental effect upon the learning and attainments of school children. Poor acoustical conditions and high noise levels can cause many problems for the instructors and students. The acoustical indices and conditions of classrooms are important factors in the learning achievement of students [4]. Noise is unacceptable level of sound that creates annoyance, hampers mental and physical peace, and may *Correspondence: [email protected] Department of Civil Engineering, Faculty of Engineering, Ataturk University, Erzurum, Turkey
induce severe damage to the health. Along with the increasing degree of air and water pollution, noise pollution is also emerging as a new threat to the inhabitants of Sylhet City [5]. Noise effects include various impacts on mental and physical health and disturbance of daily activities, which may, lead to perception of annoyance, causing hearing loss, cardiovascular problems as well as affecting task performance [6].
