摘要
Abstract
Traffic noise is the main noise factors of university campuses, especially for the new campuses which have internal roads beneath the ground. In this paper, the method of noise prediction was used to predict and assess the noise level of the new campus of Anhui University of Science and Technology so as to provide the corresponding database and technical support for the environment planning. By measuring the traffic flow and traffic noise of different types of motor vehicles in the old campus, the traffic noise prediction model of the new campus was built through the noise prediction software Cadna/ A. Then the noise distribution diagram was drawn and the corresponding noise control measures were proposed. The result shows that the noise level of the campus can meet the noise standards of domestic first-grade area by constructing enclosing wall around the campus and setting the noise barrier around the internal north-south road beneath the ground.关键词
