Title: MODERN PASSIVE NOISE-INSULATING BARRIERS FOR TRANSPORT ACOUSTIC NOISE – REVIEW. PART II
Keywords: sound-insulating barriers, traffic, vehicles, acoustic noise, noise sources

Abstract: The paper examines the main sources of noise from vehicles (road vehicles, rail vehicles, and air transport vehicles). The impact of acoustic noise on human health and the measures that lead to a reduction in its level are represented. A classification of the closed and open acoustic barriers (Sonic Crystal) type has been made. The materials, from which the acoustic barriers and the main types of structures are built, are represented. The modern tendencies for acoustic noise reduction, caused by vehicles are also represented.
