用可组装的口琴模型玩转声学原理，边做边听边懂声音怎么变。
FlueBricks: A Construction Kit of Flute-like Instruments for Acoustic Reasoning
- 模块化组装口琴零件，动手体验吹孔、管长、音孔如何影响音高和音色。
- 12名参与者在实验中反复切换设计与演奏角色，自发形成声学认知闭环。
- 适合音乐教育、创客教学或对声学互动设计感兴趣的人。
我们提出FlueBricks，一个通过构建和定制类口琴乐器来实现声学推理的拼装工具包。通过组合体现不同气动声学特性的发声模块、共振腔和连接件，用户可通过亲手操作理解吹孔、管长与音孔位置如何改变起振、音高与音色。这一设计-演奏循环形成声学推理机制，使传统静态乐器转变为动态系统。为探究用户如何使用该系统，我们对12名参与者（从新手到专业音乐家）进行了探索性研究。观察发现，参与者能灵活切换设计者与演奏者角色，基于熟悉乐器进行设计搭建，逐步形成对管长、音孔及发声结构的声学认知；还能突破模块原定用途，将创作用于教学展示与音乐表达。结果表明，FlueBricks具备作为具身声学推理教学工具的潜力。
原文摘要 · Abstract (English)
We present FlueBricks, a construction kit for acoustic reasoning via building and customizing flute-like instruments. By assembling generator, resonator, and connector modules that embody various aeroacoustic properties, users gain deeper understanding of how blowhole, tube length, and tone-hole placement alter onset, pitch, and timbre through hands-on experimentation. This forms a designer-player loop of configuring and playing to form, test, and refine acoustic behaviors-acoustic reasoning-shifting acoustic instruments from static artifacts to dynamic systems. To understand how users engage with this system, we conducted an exploratory study with 12 participants ranging from novices to professional musicians. During their explorations, we observed participants fluently switching between designer and player roles, scaffolding designs from familiar instruments, forming and refining their acoustic understanding of length, tone holes, and generator geometry, reinterpreting modules beyond their intended functions, and using their creations for performative acts such as pedagogical showing and musical expression. These collectively demonstrated FlueBricks's potential as a pedagogical tool for embodied acoustic reasoning.
