Abstract

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.

IRIS:一种基于声学周期复合材料的可调谐声音雕塑，用于音乐表演

本文讨论了在表演过程中使用声音雕塑作为声源传输特性的可调调制器。我们提出IRIS，这是一个由两个具有周期性穿孔和独立旋转的圆盘组成的声学双渔网组成的周期性复合材料雕塑。通过对传输场和双耳脉冲响应的分析，我们观察到一个声音聚焦，其频谱和空间位置随圆盘之间的相对旋转角度而变化。这种效果通过合成的持续音和和弦进行验证，并最终在11位音乐家的听力测试中进行感知验证。

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.
