Abstract

Urban activities of various kinds are contributing to sizable noise and it is becoming serious concern. The noise is found to have serious effects on quality of life, particularly with reference to health and psychology. In view of this, the study of noise assumed importance in recent times. In urban areas, most of the noise comes from traffic, heavy industry, construction activity and machinery. The noise resulting from traffic and similar activities is found to be prominent at lower frequencies. We studied the noise contributed by cutting machines mostly used during construction activity. The noise was recorded and data analyzed for frequency distribution and it was found that there is qualitative difference in the frequency distribution of noise as compared to noise due to other sources. The noise due to cutting machines is found to be spread over a wide range of frequencies in contrast to that due to other sources. It is known that the noise at higher frequencies is more annoying and has adverse effect both on health and psychology of the residents in nearby areas. Details of findings are presented.
