The environment's protection is one of the most actual problems, because of the fact that pollution is a major danger for planet life. The environment's pollution is caused because some pollution agents are in too large a quantity for a long time and they become dangerous for human health, for the flora, for the fauna and for the constructions too. The pollution sources can be classified as natural and artificial sources. The quality of the environment from a specific area at a certain time can be determined by: a) the air quality; b) the water quality; c) the soil quality; d) the health level of the population; e) the decrease of animals and plants species that are accounted for. In the paper there are given the urban traffic on the principal routes inside the Cluj‐Napoca municipality. The traffic is the constituent part of the research activity of the national project having the destination the monitoring of the noise and vibrations into an urban agglomeration, applied to the Cluj ‐ Napoca town. This study is the first step for the "noise map" asked for by the Romania integration in the European Union for the team researchers of TUCN under the the direction of Dr. Mariana Arghir.

The present paper contains our study regarding the diminution of the urban noise using the phonique barrier walls conformed to the EMPARA procedure, which is based on the simplified of the standard method for the measurements and computes of the surface traffic inside the urban agglomeration, as they are given in SRM2 laws (Netherlands standards). There are made the studies taking into account all the parameters that characterize the the noise and they are graphical representations having the “n‐1” constant parameters and only one having the time variation law. In this way we are obtained the influence of each parameter in the diminution of the urban noise using the phonique barrier walls. In addition we realized a measurement for a real barrier wall inside the Oradea town. The comparison between them was enough good, that means our theoretical study is correct and characterizes the noise pollution and its diminution on the urban agglomeration. The measurement device was a CENTER 322 Sound Lever Meter. This study contains the two steps for the “noise map” asked for the Romania integration in the European Union, and was made by the researchers of the Oradea University under the direction of the Prof. Dr. Ing. Mariana ARGHIR from the Technical University of Cluj‐Napoca.
