Biography

Dr Densil Cabrera is a senior lecturer in audio and acoustics in the Faculty of Architecture, Design and Planning , University of Sydney. He is the director of the Graduate Audio and Acoustics program.

He did his PhD in psychoacoustics at the University of Sydney. Earlier degrees include a Master of Arts (University of Technology, Sydney), Graduate Diploma in Communication (University of Technology, Sydney) and Bachelor of Music (University of Sydney). He is the original author of the computer program PsySound, which is for the analysis of sound recordings using acoustical and psychoacoustical methods. He has done work in sound art, especially in art gallery-based sound installations.

Current and recent research projects have been in applications of psychoacoustical models, opera singer vocal quality, auditory spatial perception, room acoustical quality, and auditory display. Research collaborations have been with other faculties, other universities in Sydney, and universities in Japan, Korea and Italy.

He has been involved in consulting projects in areas such as acoustics education, auditory display design, building acoustics and auditorium acoustics.

He is a member of the Audio Engineering Society, and is involved in the Sydney section organising committee and the Technical Committee on Human Factors in Audio Systems. He is a member of the Australian Acoustical Society. He represents the University of Sydney in standards development in the area of architectural acoustics.
