Most studies on the influence of the direction of late reverberation on listener envelopment (LEV) in concert halls have been conducted in laboratory conditions, i.e., where synthetic sound fields and a relatively limited number of loudspeakers were used to approximate a real, spatially quite complex acoustic situation. This study approaches LEV from the real acoustics. The late part of the sound field of two measured concert halls Berlin Konzerthaus and Berlin Philharmonie, auralized with a state-of-the-art reproduction method, is altered virtually regarding its’ direction. Results suggest that the figure-of-eight weighting applied in late lateral level LJ for predicting envelopment is underestimating the importance of reverberation from directions such as ceiling and rear.
