This leads to a definition of noise as undesired sound. The noise level of road traffic has always been difficult to quantify in terms of tolerance. This is due to individuals having a considerable difference in tolerance to noise levels, and different types of noise vary considerably. Most road traffic noise in urban areas may result from a number of different things i.e. engine and transmission noise etc. Traffic noise in urban areas is on the increase and is worsen by the fact that, because of the higher standards of living in this country, nearly everyone has a vehicle. This study was aimed at accessing noise pollution in an urban area, showing that noise levels in the chosen sight was particularly high, and that it was coming mainly from transport. However was it mainly down to the traffic itself, perhaps the road itself needed to be taken into consideration. It has been recognised for some time that although concrete roads are strong and durable, traffic produces more noise when travelling on them than on conventional, so-called black top roads. On inspection it was found that the road was not concrete but the black top/tar road. The site that was chosen, is at a junction where Harborough Avenue meets Prince of Wales Road (See map, indicated by red arrows). ...read more.

When the average is calculated then the results will be rounded to the nearest whole number. This is much easier to show on a graph.

Conclusion

This may become worse in the summer when the windows and doors are left open due to the heat. Continuous exposure to these elements for these residents is hard to define when no research was done to see if their health was at all affected. Results from T-test The results from the T-test showed that there is a difference in the average noise levels coming from both the west and the north side of the junction, therefore the null hypothesis is accepted. Conclusion Facts about noise in general: 1. 32 million people in the UK are exposed to high levels of noise, according to Government figures. 2. Britain's cities are up to 10 times noisier than a decade ago. (Sheffield University study) 3. The tranquil areas in the countryside are fast disappearing. Noise blights the quality of life for millions of people, particularly those living beside busy roads or under flight paths. (UKNA Noise and Liveability: The Odd Couple) 4. It is estimated that 2.5 million people live in homes with bad sound insulation. (UKNA A sound solution) 5. Noise harms more than our ears. Studies have correlated noise with physiological changes in sleep, blood pressure and digestion (Noise & Health leaflet League for the Hard of Hearing, NY) Upon completion of my investigation I found that, I have completed my objective of researching into urban noise pollution in my own area of living. I found that the noise levels that were recorded, was considerably high. However, this was expected as the site chosen was a route that a main road junction. The area was residential and further study including actually asking how the residents felt about the noise and how it affected them were taken into consideration but in the end was not carried out. This would have aided my aim in showing that noise in that particular area was high. It was also interesting to find to my dismay that noise levels on the weekend (Sunday) was relatively high. The graphs showed no major difference when compared to graphs during the week. ...read more.
