Sažetak

The present work examines a single-nave hall located within the Cellars of Diocletian’s Palace in Split, Croatia, constructed during the period of ancient Rome, at the end of the 3rd century AD. Since the excavation of the Cellars, no acoustic treatment has been implemented to adapt the hall for contemporary usage. Currently, the hall is not utilized for musical performances, as they require acoustic conditions different from that were considered ideal during the Roman era. An acoustics analysis of this basilica-shaped hall was conducted in room acoustics simulation software to evaluate its potential for contemporary musical performances. The study revealed that the empty hall exhibits inadequate values of room acoustic parameters in terms of excessively high reverberation time and early decay time, as well as low values of speech and music clarity and definition, which is in line with the physical characteristics of the hall. Nevertheless, the hall is deemed suitable for acoustic adaptation which would increase its potential for hosting musical performances. Comparable spaces from various historical periods with similar physical characteristics such as interior shape, proportions and material reflectivity were analysed using data from literature to contextualize the acoustic value of this hall and its historical significance.
