In the last decades, many cities of the Buenos Aires Province, in Argentina, have grown significantly. This expansion was a disorderly process, and produced important damage to environmental quality, expressed among other things, as high levels of acoustical contamination. Not many measures have been taken in order to obtain an effective solution to this problem. The cities’ governments could only take limited action using several regulations which only partially answer the people’s complaints. Regarding this situation it becomes necessary to create legal regulations for the jurisdictions mentioned before, in order to include the whole matter from a holistic and systematic point of view. The purpose of this law is to create an easy tool for the cities’ governments to use, thus allowing them to deal with the acoustic contamination problem in a global manner, and not in a fragmented way as it is now. The proposed law is oriented to the prevention, monitoring, and correction of the acoustic contamination for the whole provincial jurisdiction, and brings together as an innovation the fields of environment, planning, and noise.
