The main source of environmental (ambient) noise is transport. Road traffic is the most widespread source. Percentage of the population exposed to different noise levels is high. People in urban areas are exposed to the highest levels of noise, because of concentration of population and traffic in the cities. Most worrying is a significant increase in noise at night, because people are most sensitive to noise at that time.
