Cars honking, fire sirens, air conditioners, public works, music neighbors, passersby on the street, planes, trains, etc. And if you live near a school, a playground, a bar or a nightclub, do not talk about … The street generates noise and we can not do much about . Even with double or triple glazed windows, it is not always easy to stay in peace and quiet at home.
