Noise-Driven Instrument Based on Coherent Quantum and Stochastic Oscillator Models
- 基于量子与随机振荡的类比，设计无反馈电磁激励系统。
- 产生密集均匀的频谱分布，区别于传统确定性弦振动。
- 适合实验音乐、现场演出与科学艺术融合创作。
近年来，量子物理与声音合成交叉领域的研究为乐器设计和声音探索开辟了新的概念与技术路径。本文探讨量子系统与经典非确定性系统之间的形式类比在真实声学现象生成中的潜力。具体而言，研究如何将量子力学概念不仅作为隐喻，更作为新音乐工具设计的操作框架。基于近期关于随机弦激发的理论工作，我们提出了一个定制化噪声驱动电声弦乐器的设计、制作与频谱表征。该系统采用开环随机电磁激励，无反馈或音高稳定机制。结果表明，这种激励策略产生了密集且均匀分布的频谱区域，显著区别于传统的确定性弦激发方式。本研究为量子音乐创作领域提供了兼具艺术与科学性的混合平台，具有现场表演、实验作曲及科学教育等潜在应用价值。
原文摘要 · Abstract (English)
In recent years, emerging research at the intersection of quantum physics and sound synthesis has opened new conceptual and technical possibilities for instrument design and sonic exploration. This study investigates the potential of formal analogies between quantum systems and classically non-deterministic systems for the generation of tangible acoustic phenomena. Specifically, it explores how quantum mechanical concepts can serve not only as metaphors but as operative frameworks in the design of new musical tools. Building on recent theoretical work on stochastic string excitation, we present the design, fabrication, and spectral characterization of a custom-built noise-driven electroacoustic string instrument. The system implements open-loop stochastic electromagnetic actuation without feedback or pitch stabilization. We show that this excitation strategy produces a dense and uniformly distributed spectral regime that differs from conventional deterministic string excitation. This work contributes to a growing field of quantum music creation by offering a hybrid artistic-scientific platform with potential applications in live performance, experimental composition, and science education.
