Bastian Building Acoustics Software
Overview
BASTIAN is the software-tool to calculate the airborne and impact sound transmission between rooms in buildings and the airborne sound transmission from the exterior. The calculations in BASTIAN are based on parts 1 to 3 of the European Standard series EN 12354, being adopted by the majority of the European countries as part of their national standards. Therefore, these calculation procedures form the common basis for the prognosis of sound insulation of buildings. BASTIAN can be applied to predict the acoustical performance between rooms in apartment and office buildings, or classrooms in schools, and between rooms in hotels or hospitals.
The calculation of sound transmission with BASTIAN considers all sound
transmitting elements and systems which are relevant for a specific
room-to-room situation. In addition to the separating and the four flanking
elements, doors and windows can be inserted into the separating
construction. Furthermore, flanking elements or even airborne sound
transmitting systems, such as ventilation and cable ducts, can be added.
BASTIAN offers several databases supplying the acoustical data of a number of building elements, as there are walls, floors, roofs, facades, additional layers (wall linings und floating floors), and windows, doors and glazings.
The calculation results are presented - depending on the calculation model selected - as spectrum or as single-number rating. When calculating the interior level the outside facade level can be imported from CadnaA-project files.
The optional program extension BASTIAN-Auralization renders the calculation results for airborne sound transmission between rooms and from the outside audible for various interior and exterior sound sources and for different kinds of receiving rooms. BASTIAN-Auralization is a pure software solution, not requiring any additional hardware.
