The basic aimof standardization in the field of building acoustics is to create the conditions tomeet the basic requirement No. 5 "Noise protection" contained in the European Parliament Regulation 305/2011 on construction products and in the Polish Construction Law. In order to properly standardize "noise protection" it is necessary to specify: parameters, by which the acoustic properties of the products and structures and the acoustic conditions in the environment are determined and evaluated; metric and computational methods used to determine acoustic parameters; requirements for buildings and their surroundings. The level of acoustic requirements for buildings and the external environment is determined by the individual countries and is quite varied depending on the economic possibilities. The evaluation parameters and methods of their designation are normalized at global or European level, within the framework of the work of the ISO/TC 43/SC 2 "Building Acoustics" and CEN/TC 126 "Acoustic properties of building products and of buildings". Implementation of the EN/ISO norms for Polish standardization is dealt with by PKN Technical Committee No. 253 "Architectural Acoustics", which co-operates with the aforementioned Committees.
