Verification of Calculating Sound Insulation of Building Structures According to EN 12354 with the Results of Measurements in Site

Abstract

Currently, different computing programs, such as Bastian, SONarchitect, etc., which are designed to estimate (calculate) airborne / impact sound insulation of dividing constructions, sound insulation of building envelopes, sounds levels of acoustic powers emitted from building envelopes and other parameters, are being increasingly used in the project preparation phase of buildings. These programs, in most cases, carry out the calculation according to EN 12354 - 1, 2, 3, 4, 5. The computational model is based on the measured values characterizing the direct or indirect transfer through side paths of building constructions (by using laboratory measurements) and on theoretically derived methods of sound propagation in building constructions [. The result of proper modelling of the structure, or the entire object, should give the best estimate of acoustic parameters compared with the measured values carried out directly at the site under EN ISO 140 [2].
