Even if the title is deliberately forced and in an opposite trend, noise pollution is for real one of the greatest trouble of modern civilization. In fact, the actual society ferment foresees always open construction sites, airports with more and more traffic, crowded nightclubs and overall an increasing heavy industrialization, all these phenomenon put under big pressure the eardrums of almost 50 million people just in Italy (source: World Health Organization).

How is it possible to reduce this kind of pollution? Very often to solve this problem committees dedicated to this problem arise in every city, but unfortunately regulations and legislation in this sector are still undeveloped and the various interpretations are very different from one another.

But what does it practically mean noise pollution and what are the complications that it can cause to the human body?

To this purpose, this kind of pollution can easily be compared to the most classical spoil of the urban and natural habitat by mankind and by his efforts in modifying the natural environment he lives in. When the damage is caused by a protracted and excessive exposition to high intensity noises, the pollution threshold level is of course surpassed.

Every time the pollution threshold level is surpassed, the noise can generate some very serious physical and mental problems such as: deafness and other auditory illnesses, but also the stress level grows and by consequence also the hypertension.

As we said before, noise pollution is mainly caused by construction sites, airports, traffic and air traffic, but also and in particular by factories. This is just why all these activities have always been decentralized from the rural life and located at the city boundaries. Unfortunately or maybe fortunately, it depends from which side you are looking at this trouble, population keeps increasing in number but without any kind of structured development. This would require some kind of territorial and spatial development plan for the city that also lacks natural resources. These two problems summoned together lead up to the maximum exploitation of the areas surrounding these noise sources (and so also pollution sources). The main causes of noise pollution in Italy are construction sites, airports, traffic and factories.

It is just keeping in mind this last and fundamental detail that we all need to work together in order to limit at most every type of high intensity noise emission. This can be possible just investing on the research and development sector and equipping heavy industry factories, for example, with soundproofing cabins where machines that utter strong noises can be all contained.

Also some kind of air treatment turn out to be fundamental, because is a real natural soundproofing system, for all these reasons it is very important to study and project the best possible air treating systems in order to silently convey air fluxes and this way exploit every isolating characteristics of this natural elements.

It is also fundamental, then, for every enterprise and civil house, the use of soundproof materials to apply on houses and factories? walls, this allows the external noise not coming into our houses and in the meanwhile limiting the emissions outside of the domestic or industrial noise pollution.
