Sažetak
Reverberation is a well-known acoustic factor for architectural design. The idea of appropriate and diverse reverberation times along baroque enfilades (a specific series of rooms in manor houses) served as an inspiration to investigate if similar perceived quality can be achieved in open spaces. The sequence of public spaces in Zagreb, Croatia, was chosen for the initial stage of this study. Reverberation time was measured using firecrackers as impulse sound sources. The measured values clearly supported the idea of a spatial sequence within a span from public to intimate. However, in recorded scenarios, analyses of soundscape perception descriptors, showed that other factors, such as traffic noise, probably cancelled the hypothetical effect of diverse reverberation times. Further research was conducted on a morphologically different but acoustically comparable sequence of public spaces in Sheffield, United Kingdom, to investigate factors that make reverberation in open space more significant for the overall assessment. The research includes a total of 17 squares, 8 in Zagreb and 9 in Sheffield, which were assessed using similar methodology on both locations. Spherical photographs and three- dimensional audio recordings were made to serve as a basis for listening experiments conducted in auralisation laboratory using tools for virtual reality simulations. It is expected that further research would show which features are most significant for the perceptibility of the investigated concept.
