Musical performances must be organised in line with regulations on protection from noise pollution. As indicated in art. 47 of Italian Presidential Decree 455/2000, a declaration must be obtained that certifies that the methods used to organise the musical performance are compliant with regulations regarding the urban areas next to the place where the performance is to be held.
Should the maximum levels established by the Prime Ministerial Decree of 14th November 1997 “Definition of maximum levels for sound sources” be expected to be exceeded, the performances should respect the “Guidelines for the issue of authorisations for events in a place that is public or open to the public and for temporary or mobile performances”, approved with City Council Resolution no. 1076 dated 23rd May 2014; the guidelines are attached here and also appear on the Web portal of the Municipality of Milan.
Section 14 of the Integrated Form for public performances and temporary events during Expo in Città is deals with noise impact.
See attachment 3) “Guidelines for the issue of authorisations for events in a place that is public or open to the public and for temporary or mobile performances”
