Is your work place safe enough and comfortable with the noise level you get ? Does this affect work productivity ? Can the noise level be detected on a whole area ?
A Noise Map is a map of an area which is coloured according to the noise levels in the area. Sometimes, the noise levels may be shown by contour lines which show the boundaries between different noise levels in an area.
The noise levels over an area will be varying all the time. For example, noise levels may rise as a vehicle approaches, and reduce again after it has passed. This would cause a short-term variations in noise level. In the slightly longer term, noise levels may be higher in peak periods when the roads are busy, and lower in off-peak periods. Then again, there is a greater volume of activity from more people and traffic in the day-time than in the evening or at night. In the longer term, wind, weather and season all affect noise levels.
For these and other reasons, noise mapping is usually done by calculation based on a computerized noise model of an area, although measurements may be appropriate in some cases.
A further benefit of having a noise model is that it can be used to assess the effects of transportation and other plans. Thus the effect of a proposed new road can be assessed and suitable noise mitigation can be designed to minimize its impact. This is particularly important in noise action planning, where a cost-benefit analysis of various options can be tested before a decision is made.
