IRIS: A tunable sound sculpture based on acoustic periodic composites for musical performance
This article discusses the use of sound sculptures as tunable modulators of the transmission characteristics of acoustic sources during performance. We propose IRIS, a sculpture consisting of a periodic composite formed by an acoustic double-fishnet made up of two discs with periodic perforations and independent rotation. From the analysis of the transmitted field and binaural impulse responses, we observed a sound focusing whose spectral and spatial location varies depending on the relative angle of rotation between the disks. This effect is verified using a synthesized sustained sound and a chord progression, and finally validated perceptually in a listening test with 11 musicians.
期刊介绍：
The Journal of New Music Research (JNMR) publishes material which increases our understanding of music and musical processes by systematic, scientific and technological means. Research published in the journal is innovative, empirically grounded and often, but not exclusively, uses quantitative methods. Articles are both musically relevant and scientifically rigorous, giving full technical details. No bounds are placed on the music or musical behaviours at issue: popular music, music of diverse cultures and the canon of western classical music are all within the Journal’s scope. Articles deal with theory, analysis, composition, performance, uses of music, instruments and other music technologies. The Journal was founded in 1972 with the original title Interface to reflect its interdisciplinary nature, drawing on musicology (including music theory), computer science, psychology, acoustics, philosophy, and other disciplines.
