It should be no surprise to any fan of symphonic music that the "shoebox" design would have superior sonics. It’s been effective for hundreds of years. The newer concept designs listed in the article have not been reviewed yet.
It’s widely recognized that the performances by the Berlin Philharmonic in the Jesus-Christus-Kirche, an old church, had superior sonics to the modern Philharmonie concert hall.
Today’s acoustic engineers are hellbent on adding absorption, diffusion, and reflection panels decided by computer programs rather than trying the natural design and surfaces of the concert hall first. Granted, they have to deal with some crazy designs put forth by the architects.
Here in Philadelphia we have one of the worst designs (acoustically) of any concert hall in the US. It has negative reviews for sonics in newspapers and trade publications, and when a proposal was asked for to overhaul the acoustic design by a top engineering firm, it was rejected by the new board of directors.
It’s widely known that the musicians hate the acoustics because they can’t hear each other due to overdamping.
