项目摘要
Architectural sound-absorbing technologies are often constrained by traditional techniques represented by porous**materials, vibrating panels and perforated ones. With the available technologies, the broad absorption of middle**frequency noises typically requires large thicknesses of POROUS materials. As this creates space issues, there is a**demand for thin broad frequency absorbers. The possibility to generate passively destructive interferences, a**principle generally used in active noise control, has been recently considered in innovative soundabsorbing**treatments. A destructive interference occurs when two interfering sound waves are in counter-phase. This**project aims to develop an acoustic panel using passive destructive interference tubes. The new acoustic panel**will be composed by a SERIES of tubes, whose length and diameter will be defined according to the frequency to**absorb. Several passive resonators will be assembled into each panel for a broad-frequency absorption. The**project aims to develop and investigate various prototyping methods via additive manufacturing, after having**encoding rules for the design generation. As the work deals with highly complex geometries, digital fabrication**will enable design freedom. Another required characteristics of the targeted panel will be its transparency. This**characteristic enables to obtain a panel that can be suspended within a space or mounted into interior glazed**partitions without stopping light transmissibility. WIREP and the research team will compare different additive**manufacturing techniques and several transparent ABS and resins. The aim is to produce new 1mx1m panels to**support further the company leadership in new sound absorbing approaches for room acoustics.**
建筑吸声技术往往受到以多孔材料、振动板和穿孔板为代表的传统技术的制约。利用现有技术,中频噪声的广泛吸收通常需要大厚度的多孔材料。由于这会产生空间问题,因此需要薄的宽频率吸收器。产生被动破坏性干扰的可能性,一个通常用于主动噪声控制的原则,最近已经被认为是创新的吸声处理。当两个互相干涉的声波相位相反时,就会发生相消干涉。本项目旨在开发一种使用无源相消干涉管的声学面板。新的隔音板 ** 将由一系列的管组成,其长度和直径将根据吸收的频率来定义。多个无源谐振器将被组装到每个面板中,用于宽频率吸收。** 项目旨在通过增材制造开发和研究各种原型制作方法,在为设计生成提供 ** 编码规则之后。由于这项工作涉及高度复杂的几何形状,数字制造 ** 将实现设计自由。目标面板的另一个所需特性将是其透明度。这种特性使得能够获得可以悬挂在空间内或安装到内部玻璃隔断中而不阻止光透射性的面板。WIREP和研究团队将比较不同的增材制造技术和几种透明ABS和树脂。我们的目标是生产新的1mx1m面板,以 ** 进一步支持公司在室内声学新吸声方法方面的领导地位。**
