Traffic noise measurement and analysis in Jeddah

Road Traffic Noise in Nigeria: Measurements, Analysis and Evaluation of Nuisance

“…Respective values of¸B L and¸C O were calculated as 68)0 and 84)6 dB (A) and sometimes higher. In Jeddah city, road tra$c noise has also been found to be very intense and sound pressure levels of 90 dB (A) and higher were recorded in many cases [9]. The results of this investigation are in agreement with those of Galt [35] who earlier measured maximum outdoor noise in the streets of New York and found them to be of the order 90}100 dB and 65)8}67)0 dB (A) (55)5}58)2 dB(A)) foŗ were also measured at the facade (and inside) in the majority of the school-hospital sites.…”

“…Hall and Taylor [7] found several noise measures, (¸C O , and the day}night average sound level,¸B L ) to be equally good predictors of subjective response and concluded that the reliability of the predictions can be validly estimated by using the standard errors of regression estimate, thus strengthening the basis for such predictions. Although it has been reported that road tra$c noise in developing countries has not yet been recognized as a major problem [8], work carried out in Jeddah city [9,10] indicates that noise from road tra$c is very intensive, and relatively high sound pressure levels (90 dB (A) and higher) were recorded in many cases. Recent work [11] has shown that in the Nigerian environment the kind of noise that bothers people most is road tra$c noise.…”

Social Attitudes and Traffic Noise: A Study in Riyadh, Saudi Arabia

“…Results of preliminary studies of traffic noise in the Kingdom of Saudi Arabia also indicate that the problem of noise is significant both in populated urban areas and in the vicinity of industrial complexes (El-Sharkawy, &Abou Khashaba, 1983). These studies provide insight concerning the existence and the magnitude of the environmental noise problem in the cities of Saudi Arabia.…”

Community responses to road traffic noise in Hanoi and Ho Chi Minh City

“…Since 1992, the number of public complaints of such noise has increased in Europe [13]. Although road traffic noise has not yet been recognized as a major problem in developing countries [14], studies carried out in some of these countries show the potentially adverse effects of noise in communities where road traffic noise is very intensive (e.g., up to 90 dB of sound pressure level in Jeddah) [15,16]; it was also listed as a major environmental problem in Nigeria, with traffic noise bothering the people most [17,18]. In Asia, except for a handful of studies [19][20][21][22][23][24][25][26], there is a rather limited knowledge from published surveys on road traffic noise status and its influences on the community, especially within developing countries.…”
