Receiving the Discovery ARC grant for stage acoustical quality in auditoria

Congratulations to Alumni Densil Cabrera, Senior Lecturer, PG Program Director Audio and Accoustics, and Bill Martens, Associate Dean, Research Graduate Studies, on the award of the Discovery ARC grant for stage acoustical quality in auditoria: measurement, simulation, prediction and design

Research Team:
Dr Densil Cabrera ,The University of Sydney, Lead Chief Investigator (PhD in acoustics 2001)
A/Prof William Martens, The University of Sydney, Chief Investigator
Prof Jin Yong Jeon, Hanyang University, Partner Investigator (MDesSci in building science, 1991 and PhD in acoustics in 1994)

The Sydney Opera House is one of Australia’s most prominent cultural icons, and yet for musicians and acousticians, it is well-known for its seemingly intractable acoustic limitations. The Sydney Opera House, unfortunately, serves as a reminder of the importance of good performance acoustics, including acoustics for musicians as they play or sing. It is unsurprising that for the Sydney Opera House, stage acoustics would have been a hit-or-miss affair, because almost no research had been conducted into stage acoustics at the time when it was designed and constructed. Even today, the field of stage acoustics has basic questions remaining to be answered, and this project aims to answer key questions in this field.

This project asks what acoustic qualities make a concert hall stage outstanding for musicians, and how can these qualities be achieved? It involves a collaboration between acoustics researchers in Australia and Korea, with complementary expertise in lab and field studies of auditorium stages.

The acoustic conditions on a concert auditorium stage have a profound influence on a musical performance. The goal of this study is to develop a set of principles for the acoustic design of stages: and to achieve that, this project will develop innovative and powerful methods for measuring, assessing and simulating stage acoustical conditions. Currently, there are many unknowns in the field of stage acoustics - partly because of contrasting findings between field and laboratory studies, and partly because of the lack of adequately established parameters predicting stage acoustical quality. This project will integrate lab and field work into a single study, and will develop new spatially sensitive assessment methods for stage acoustics.
