It is universally recognised that noise is both a nuisance and a proven health hazard. The proof is that half of the population of Europe lives in a noisy environment and one third of that population have their sleep disturbed by background noise. Workplaces, leisure environments, MP3 players, etc. – other sources of excessive noise can also cause serious damage to your ears. Consequently it is essential to warn and inform people about the health risks involved. This is why most European countries are dealing with this issue by enacting noise prevention regulations in order to increase acoustic comfort in new buildings.
