In one of these studies. Noise pollution and its causes 3. Accordingly, the area of Arraba town is considered an unacceptable living area. Simultaneous measurements of noise levels, vehicle flow, and traffic composition were made around the main roads inside the urban perimeter of Curitiba. I, Noise does not pollute the air, water, or lan. By Debnath, D. , Nath, S.K & Barthakur, N.K. Environmental problems include many anthropological hazards, in which noise pollution is of primary significance. In conclusion, the proposed methodology showed to be consistent and can be exploited to verify its accuracy over new cities so asses the quality of the proposed models. It is represented by, The noise levels are classified depending upon the, There are two concepts or criteria related to th, person. In addition, P-value between the dependent and independent variables was found to be zero. By measuring the amplitude and frequency of a noise source, engineers can select acoustical materials to squelch airborne noise and use vibration dampers or special foundations to suppress structure-borne noise. © 2015 Institute of Noise Control Engineering. All content in this area was uploaded by Issam Ashqer on Feb 19, 2014. Disaggregation of noise by source type during a measurement programme could make the collection of noise data in urban noise surveys more efficient. Abstract Rapid urbanization and industrialization eventhough facilitate our lives, leads to various forms of environmental pollution. Noise pollution has hazardous effect on human health. Industrial noise is a serious environmental problem, which causes annoyance and disruption to daily activities. In this study SBP, DBP and HPR are correlated positively (p-value < 0.050) with the occupational noise levels in all studied hospitals. The other effects of noise pollution are: the cardiovascular system, rate of heart be, There are three basic techniques which could be a, b. exceeding 65.0 dB(A). The details of all publications are in the researchgate in full text pdf forms. The effect of EMR on students health were explained as follows, there was increasing in tympanic temperature, heart pulse rate, arterial blood pressure (systolic and diastolic), on the other hand the blood oxygen saturation was decreased. It was also a repetition of a similar study carried out 10 years earlier. levels, the owners of factories pay little attention to safety measures for their workers.Accordingly, this study is concerned with measuring the equivalent noise levels Leq in 38 factories in Nablus city and comparison with international standards of noise. For additional sound absorption, acoust, have tiny holes that trap the sound and prevent, Insulation against sound, reduces the no, factories have sound barriers between the wo, by national and global bodies. Social surveys of the relationship between noise exposure and the subjective reactions to it were reviewed. The aim of this study is to evaluate noise pollution from the use of household electricity generators in a high-density residential area. Unusual sound can disturb any human being, birds, animals and their activities. Noise pollution is becoming more and more important, especially in the industrialized and developed countries. There was a significant test difference (p < 0.05) in the means and variances of the noise level in the study area and the WHO standard. Access scientific knowledge from anywhere. This objective implies more than reducing noise pollution and the exclusively consideration of the acoustic context of the place. The combined methodology ensures acoustic comfort for all the occupants of the building without any waste of resources, avoiding insufficient or excessive facade sound insulation. The ages of the sample workers were ranging from 20 to 73 year. In all the sites average daily sound levels was 14 dB higher than environmental standards due to street traffic and peculiar geo-morphological structure of the town. Two main steps have been conducted: first, a survey using questionnaires and involving a sample of 2000 people; and second, 24-hour noise measurements at the front of the dwellings of a sub-sample of 375 people. Noise Pollution PPT and Free PDF: Noise pollution can be defined as the excessive noise that disturbs the activities of animals or humans.The major sources of this pollution come from the motor vehicle engines, trains, aircraft, transportation systems, and systems. It has been found that the Leq values for 60% of the selected locations are exceeding 65.0dB(A). A work done under DST funding during 1993-95. which is a recurring problems of the public.
