When not properly designed, large halls, theaters, churches, and meeting rooms can exhibit a variety of acoustical problems, including echoing, booming, and high ambient noise levels. Many of these problems can be predicted and measured through reverberation time studies, which establish sound decay time in an enclosed area. Desirable reverberation time allows frequency components to […]

CadnaA Environmental Noise Prediction Software
CadnaA (Computer Aided Noise Abatement) is the leading software for calculation, presentation, assessment and prediction of environmental noise. It can be used efficiently at any scale, starting with a few single receivers in a neighborhood up to noise mapping projects of entire countries. This works for various source types in fields of road-, railway-, aircraft-, […]
Bastian
BASTIAN is the software to calculate airborne and impact sound transmission between rooms in buildings and airborne sound transmission from the exterior. The calculations in BASTIAN are based on parts 1 to 3 of the European Standard series EN 12354. BASTIAN can be applied to predict the acoustical performance between rooms in apartment and office […]
