Atriums in modern life have changed their activity patterns from circulation zones to hosting vast range of activities. Optimizing reverberation time is one issue of these atriums regarding acoustical comfort. Nonetheless, the acoustical criteria for atriums or public foyers are not yet well established. This unknown leads to an excessive use of acoustical materials for newly built atriums or, in the case of refurbishments. This study aims to propose an optimal range of reverberation time metrics (T30 and EDT) for atriums, which can later be extended to other large public interiors. The methodology includes field measurements, surveys, ray-tracing simulations, and listening tests. The impact of demographic characteristics of users, duration of stay, and activity patterns are compared in different atrium spaces of Bilkent University over a sample group of undergraduate students. Field test-tuned ray-tracing models are used to experiment with different amounts of sound absorption application to alter EDT and T30 values. Participants' preferences are checked over audio clip pairs of different decay rates gathered from auralizations. The results indicate that the participants prefer 1.00 s
