Acoustic conditions in the atrium of Slovak philharmonic

摘要

Musical performances, conferences, receptions or other events when many people gather can take place in different types of rooms and large shopping centrums, atria or city courtyards are not an exception. Continental weather however, doesn't allow for keeping these semi-open spaces uncovered, in case of the whole year operation. Volume, shape and material choice of interior surfaces in atria are typically hard and thus sound reflective, which has very strong influence on acoustic comfort inside. This article analyses acoustic conditions in the atrium of Slovak philharmonic from room acoustic point of view and compares 5 different alternatives of a position of sound absorption in terms of its efficiency and adaptation of an atrium space for music performances, conferences or receptions.
