Traffic noise pollution has become the most serious and pervasive type of noise pollution. Noise is adisturbance to the human environment that is escalating at such a high rate that it will become a major threat to thequality of human lives. The present study provides an evaluation of noise pollution in Bistrita. The measurements weremade with the 2250 Controller Integrating Sound Level Meter (Bruel & Kjaer). Equivalent noise levels (L eq) weremeasured in 9 points (each point measured during 30 min). The measurements realized in different spots indicated thatthe highest values of the continuous equivalent acoustic level (Leq) appear on the 1st and 2nd category roads, where theheavy traffic is intense. The most noise-polluted points in Bistrita were Auto bridge and Han Road crossing: CaleaMoldovei - Năsăudului St. - 1 Decembrie (intense traffic). The highest recorded Leq values were between 83 - 84dB(A). The evolution of the traffic volume values in Bistrita is continuously increasing and there is a higher expectationfor state and local government to reduce noise levels. The Directive on Environmental Noise (2002/49/EC) developed anew framework for noise policy, based on shared responsibility between the EU, national and local level, and includingmeasures to improve the accuracy and standardisation of data to help improve the coherency of different actions. Inorder to reduce the noise pollution it is necessary to diminish the noise level at the sources and to apply a combinationof strategies that include noise barriers, lower vehicle noise levels and better urban planning.
