Resumen
In concert halls the walls are always thought to be the most important elements for effective early reflections, while usually in a vineyard hall people may find the area of roof ceiling is comparatively larger than walls. Thus their contents of early reflections are different, both in time and energy domain. Using computer model with ODEON, the prototype of vineyard hall developed in pilot projects was compared with four selected successful shoebox halls in similar volume or seating capacity, the acoustic performance including the strength and balance are considered. The study is focus on the amount and direction of early reflections after direct sound arrived, displayed in three different time window. The effects of altering the distribution curve of statistical free path length by changing geometric characters of prototype were also observed.
