Sound can be understood not only in a negative sense, i.e. noise, but also in a positive sense, as an asset to be protected as part of the intangible cultural heritage. From this perspective, the issue must be approached from two angles. Firstly, it must be ascertained under which conditions sound can fall into the category of cultural heritage. Then the legal basis must be sought, both in international charters and in national experiences. Existing and pending regulations, despite their limitations, demonstrate the interest that the issue is arousing in national legislators.
