Statistical Energy Model of the Passage of External Noise into the Premises of the Building

A statistical energy model of the passage of external noise into the premises of the building is proposed, which makes it possible to evaluate the acoustic regime in rooms facing the sound source and adjacent to them. The model is a set of resonant and non-resonant sound transmission paths through translucent structures, air exchange devices, through corridors and openings connecting rooms in the building. Connected rooms and enclosing structures are considered as a closed system, for which a system of energy balance equations can be written. Solving the system of equations gives the values of the acoustic energy levels in the premises and the noise levels in them.
