This paper presents some aspects about sonic pollution and vibrations sources in urban area, respectively in Oradea town with its metropolitan zone, and suppressing solutions. The noise and vibration pollution in urban area represents an actual theme of environment protection in Europe and other world’s zone. In last time, Oradea Town has known a large urban and economical development, which due to including inside of urban zone two metallic railway bridges “Oradea East” and “Oradea West”, over “Crisul Repede” River. This ambient noise level and vibration loads produced by railway bridges on passing trains must be reduce, increasing of working bridge’s age and population’s comfort. The experiments about of automotive and tram traffic influence of historical monuments and public Oradea’s buildings have been extended, such as church and hospital. The tests have emphasized the necessity of suppressing noise and vibration pollution by mounting of sonic absorbent panels near buildings from railway bridges, phonic insulation of buildings walls, hour’s restriction program of traffic in these areas, and other solutions.Copyright © 2009 by ASME
