Noise

What is noise? Noise is simply unwanted sounds. What people perceive as being noisy can vary greatly from person to person. Some have e.g. much greater tolerance than others. In addition, the experience of noise and especially the nuisance effects are not only dependent on the strength of the noise, but are also affected by objective factors. As some of the objective factors, one can highlight, for example, the nature of the noise and its variation over time. However, there are also subjective factors which can be linked in particular to the individual person's attitude towards the noise source, the possibility of control over the noise source, and the person's ability to deal with problems. It can, for example, be negative attitudes towards construction on neighboring land. Maybe you don't want the building to be built to begin with, or you are annoyed that they have blocked off a large area.

In addition to the general perception of the noise, there is also the health aspect. It is estimated that every year 200-500 Danes die prematurely as a result of road noise. People who live in places where there is a lot of noise from traffic have an increased risk of bleeding or blood clots in the brain.

"A study from 2012 by Mette Sørensen (Kræftens Bekæmpelse) shows that road noise can increase the risk of blood clots in the heart. The study shows that a 10 dB increase in road traffic gives a 12% increased risk of getting a blood clot in the heart. The figures correspond to approx. 3.7% of cases of blood clots in the heart are due to road traffic noise, corresponding to approx. 330 new cases every year in Denmark”
