Computer Studies of Optimum Classroom Acoustics

... In these spaces more recently developed acoustical criteria such as the C50, which is based on the ratio of early to late arriving energy, find significant application and investiga tion. [3], [4], [5] An investigative analysis of the C50 for the typical gymna sium space was performed using a commercially available ray-tracing software package. The results indicate negative values o f C50. ...
