“…If the sources are analyzed separately, it is noticeable that among the subjects who felt annoyed by the noise in his/her home, 50% pointed out the traffic noise was the main source of annoyance, 34% the street noise. Findings of the study showed that traffic noise has negative impacts on human health, as is reported by others (Mato and Mufuruki, 1999;Georgiadou et al, 2004). Maschke (2001) and Babisch et al (1999) have pointed out some effects of the noise over urban inhabitants: irritability, insomnia, difficulty to concentrate and headaches.…”

Traffic noise is a major environmental source of pollution in the whole planet, both in developed and in developing nations. The study being reported here has been carried out on one of the most busy and crowded streets in the downtown area of Kerman, located in south east of Iran, which have heavy traffic during the day. Total of 20 measuring points were selected along the main road and its 6 connecting streets. In this study the A-weighted continuous equivalent sound level values and statistical levels were manually measured at each site separately. The noise equivalent level varied between 66 to 79.5 dBA. The results of the study established the fact that noise levels are more than the acceptable limit of 60 dBA, which is the daytime governmentally prescribed noise limit for residential-commercial areas. This paper also describes the reaction of the environmental noise of the city of Kerman. A total of 250 questionnaires were processed. The results of the interview questionnaire revealed the following items; (I) the main isolated noise source was traffic (50%) and street noise (34%); (II) 70% of the people classified the noise in his/her street as "very high"; (III) 52% and 48% of the respondents answered that noise bother them more in morning and evening, respectively; (IV) 86% and 86.8% of the subjects answered that traffic noise produce physicsl and psychological annoyance to them; (V) the main outcomes of exposure to noise were: irritability (40.8%), insomnia (24%), difficulty in concentrating (16%) and conservation disruption (16%).

“…Periodic spikes in noise levels occurring at irregular intervals might also be more difficult for birds to habituate to than to constant background noise only a few decibels lower in intensity. Additionally, these higher peaks of noise generated sporadically may reach some threshold beyond which even less sensitive birds are affected, just as there is a threshold of noise intensity at which sounds become first an irritant to people and then actually harmful (e.g., Mato and Mufuruki 1999). Because spikes in noise levels did occur irregularly, the chances of observing bird responses to any particular spike in intensity were low and would likely not be adequately represented in my data.…”

, I surveyed 5 active, 4 abandoned, and 4 road sites to investigate the relationship between distance from disturbance (well pads, access roads) and bird abundance. I also compared abundance among the 3 site types. At each site I recorded bird numbers and species in 10-m distance bands along all transects (4 transects/well, 2 transects/road), each extending 300 m from the road or pad.At road sites bird abundance was positively correlated with increased distance from road edge, but I found no linear relationship at active or abandoned well sites.However, mean bird abundance in the first (0-30-m) distance interval of active well transects was less than half that at the second interval, and was the lowest value for all active intervals except the ninth. First-interval abundance at active wells was lower than abundance at any abandoned well interval. Road transects likewise showed low abundance in the initial interval, although unlike at active wells abundance increased steadily with distance from the center of disturbance.This trend of lower overall numbers at the first interval of active well transects was driven largely by 1 species, the meadowlark. A combination of high noise levels near active well pads (up to 80 dB) and lack of tall vegetation (on average 30% lower iv than the 60-90-m interval) from which to sing may have contributed to low numbers of meadowlarks, which were the only birds to sing regularly during my study period.While most birds appear to be minimally affected by resource extraction at Padre Island, to ensure minimal impacts on sensitive species I recommend: 1) reducing noise at active sites, 2) limiting disturbance to vegetation near pads and roads, 3) maintaining existing perch sites, 4) restoring all vegetation to its pre-extraction condition, 5) limiting road construction. v DEDICATIONTo my mother and father, for instilling in me a love of wild places of all kinds, and above all for imparting an irrepressible sense of curiosity about the world; And also to Briana, without whom it would have been an entirely different experience.vi

“…Noise pollution has been stated as a serious health hazard (Bies and Hansen, 1996), with noise-related damage to humans ranging from annoyance to insanity and death (Mato and Mufuruki, 1999). Maschke (1999) treated the impact of noise as a stress inductor, and stated that induced stress by noise has a psychosocial component.…”

The City of Amman, Jordan, has been subjected to persistent increase in road traffic due to overall increase in prosperity, fast development and expansion of economy, travel and tourism. This study investigates traffic noise pollution in Amman. Road traffic noise index L10(1 h) was measured at 28 locations that cover most of the City of Amman. Noise measurements were carried out at these 28 locations two times a day for a period of one hour during the early morning and early evening rush hours, in the presence and absence of a barrier. The Calculation of Road Traffic Noise (CRTN) prediction model was employed to predict noise levels at the locations chosen for the study. Data required for the model include traffic volume, speed, percentage of heavy vehicles, road surface, gradient, obstructions, distance, noise path, intervening ground, effect of shielding, and angle of view. The results of the investigation showed that the minimum and the maximum noise levels are 46 dB(A) and 81 dB(A) during day-time and 58 dB(A) and 71 dB(A) during night-time. The measured noise level exceeded the 62 dB(A) acceptable limit at most of the locations. The CTRN prediction model was successful in predicting noise levels at most of the locations chosen for this investigation, with more accurate predictions for night-time measurements.
