Abstract:
A traffic noise survey conducted in Lahore city, Pakistan showed that the prevailing traffic noise levels were excessively high and much above the community annoyance limits. Therefore, in order to have an assessment of the level of noise emitted by different types of vehicles plying on the roads in Lahore city, measurement of the level of noise emitted from individual cars, motorcycles, vans, buses, auto rickshaws and trucks was carried out in their normal running condition. The data collected have been analyzed for the range of noise emission levels, LV99, Lv90, Lv50, Lv10 and Lv1 values for each category of vehicles. Due to the lack of proper regulatory laws to limit emission of high level noise from individual vehicles in Pakistan, the results are discussed with reference to the vehicular noise emission limits recommended by the Council of European Economic Community, and some other individual countries. Some means and ways to limit the emission of high-level noise from individual vehicles are also suggested.
