Room acoustical quality of concert halls: perceptual factors and acoustic criteria - return from experience

摘要: Several acousticians have attempted to define a complete set of factors describing room acoustic quality, based on laboratory and/or real hall listening tests. After finishing PhD thesis the author has worked new constructions performance spaces, renovations as well optimizations existing spaces and question can now be asked whether widely used objective criteria perceptual proves sufficient describe problems challenges encountered. When working high-quality commonly is insufficient all aspects problems. Further descriptors are required with respect both measurements factors. Proposals for additional their link architecture space will given, aiming better signature source presence presence. The concept “stream segregation” into confirmed, but “source” “room” parts not only magnitude (strength) needs considered equally more detailed like “lateralness” direction arrival, i.e. what could called “spatial center gravity”. For example, changing spatial gravity reverberation very strong consequences. Another aspect that often tends neglected orchestral balance (for audience members musicians stage) strongly influenced by design decisions.
