Impact of transportation noise in some new industrial countries

Assessment of Traffic Noise Pollution from 1989 to 2003 in Lanzhou City

“…Moreover, the social survey carried out in five representative areas showed that noise annoyance was a serious problem to many residents (Arana and Garcia, 1998). On the base of large numbers of survey data, similar findings have been evaluated in Singapore, Malaysia, Japan, respectively (Heng, 1979;Kono, 1982;Sy, 1985;Nulty, 1987).…”

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

“…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. From noise measurements in schools in Korea and Malaysia it was found that noise levels inside classrooms were in the range between 55 and 70 dB (A) even though noise levels in classroom should be 45 dB (A) for reasonable communication [34]. According to the U.S. Environmental Protection Agency [36], only 45% sentence intelligibility is possible for noise level of 70 dB (A).…”

Comparison Between Measured Traffic Noise in Klang Valley, Malaysia and Existing Prediction Models

“…Nulty [17] reviewed that the impact of traffic noise is because of a trend of enhancing the noise output from noise-emitting machines by suitably adjust-ing the vehicle's silencer. A study conducted in South Eastern Nigeria [18] and in Kolkata, India revealed that sirens and horns are caused to the high environmental noise climate in these cities.…”
