DESIGN OF PASSENDGER SHELDER CONSTRUCTIONS WITH NOISE-PROTECTIVE FUNCTION OF URBAN ENVIRONMENT

Abstract

Negative influence for agglomeration ecological safety are modern growth of the cities, increase in population density, intensification of automobile transportations. The urban environment everything more becomes subject to the acoustic pollution of road traffic. Negative influence of this type of pollution on a hu-man body is conventional and is shown in the big range of influences. For example the Concept of complica-tion offered by A. Chic, which reflects subjective psychological feelings from the acoustic pollution of road traffic in the city and beyond its. The existing methods of fight against auto transportation noise is ineffectively or sometimes unaccepta-bly in the developed living area. The most acoustic pollution sites in urban environment are the locations of public transport stop points. Recommendations for design of PSC taking into account their shielding effect for the purpose of decrease acoustic pollution are developed. Possibilities of the developed computer program for design of PSC with noise-protective characteristics concerning object of a noise-protective are reflected in this work. The problem of optimization of PSC tech-nical parameters for the purpose of increase of level of security of an urban environment from the acoustic pollution of road traffic is solved. Nomograms for determination of optimum height of PSC with installation on them additional screens are developed.
