The article provides an overview of the current state study of one of the most pressing environmental problems of large cities – the problem of noise pollution. Due to the increasing number of cars, industrial machines and mechanisms to date, over 60% of people living in cities, daily exposed to excessive noise. The aim is to study the problem of noise pollution urboecosystem of Lviv and finding effective methods to combat with noise. Identified sources, the main characteristics and ways of dealing with the harmful effects of noise pollution. Established magnitude of noise burden on certain streets and filed a comprehensive assessment of the acoustic load of the city. A performance experiments noise which generated of motor vehicles when driving on different stretches of road near two intersections – st. Franko – Green and Levitsky – Tershakovciv. Near the street. Franko during bilateral traffic and trams bilateral traffic noise performance of road transport accounted 75,7dBA +/– 3.2. By reducing the transport speed to 6–10 km/h performance noise constituted 70,4dBA +/– 2.5. Indicators of noise on the Levitsky street during a stop to road transport and traffic lights at the beginning of the movement consisted 66,8dBA +/– 2.9 and 2.6 +/– 69,8dBA. Indicators of noise on the Tershakovciv street respectively amounted to 63.8 +/– 3.2 dBA and 65.2 +/– 3.3 dBA. Today, the simplest and most common methods of noise control is the discharge of roads, planting green space and installing anti–noise screens.
