The nonauditory effects of noise comprising annoyance, sleep disturbance, and psychological stress are believed to cause global disability. It is estimated by the World Health Organization (WHO) that in Western Europe a total number of 1,685,000 DALYs are lost for ischemic heart disease, cognitive impairment of children, sleep disturbance, tinnitus, and annoyance every year (2). This means that traffic noise exposure accounts for the loss of more than 1,000,000 healthy life years in the Western European population every year. Sleep disturbance and annoyance induced by exposure to road traffic noise are responsible for the majority of environmental noise-related diseases in Western Europe. It is estimated that 40% of the European population is exposed to noise originating from road traffic at levels exceeding 55โ€‰A-weight decibels [dB(A)]; 20% exposed to levels exceeding 65 dB(A) during the daytime; and 30% of the population is exposed to levels exceeding 55 dB(A) at night (2). Sound levels of different noise sources are provided in Figure 3. Asian populations living in urbanized territories may face much higher traffic noise exposures compared with European cities, even reaching Lden levels (Dayโ€“Eveningโ€“Night level, i.e., the average sound pressure level (Leq) measured over a 24-h period, Table 1) of 60โ€“64 dB(A) or more (138).
