项目摘要

An acoustic metamaterial is a material in which its acoustic properties are derived not from the characteristics of its constituent atoms, but from the shape and geometry - the way that it is built, not from what it is built. Such metamaterials can be constructed in such a way as to create material properties that are impossible in traditional materials, such as negative density and negative bulk modulus - properties counterintuitive to the way in which we expect materials to behave. Acoustic propagation in these materials is unusual, and metamaterials can be used to cloak objects from sound, to show extremely efficient noise suppression, and otherwise manipulate sound in strange ways.One issue to tackle, to make these materials more relevant to real-world applications, is one of scale. Miniaturisation of these structures is desirable to improve efficacy and efficiency, and make metamaterials perhaps wearable, i.e. such that the materials are on the scale of human endeavours. The problems are that typically acoustic systems work at ever higher frequencies as they are miniaturised, moving away from audio frequencies, and also that creating small structures to enable wearable materials in, for example, headphones, is challenging and expensive.Advanced manufacturing methods are progressing such that it is possible now to build complex geometrical objects using 3D-printing methods with features in the microscale, not least due to recent developments in our laboratories and others worldwide. This opens up the possibility of rapidly prototyping small acoustic systems - miniature musical instruments - that can be stacked together to create acoustic metamaterials, while still working at audio frequencies.In this project, we seek to establish new acoustic systems built with microscale features that operate at audio frequencies pulling together advances in 3D printing and acoustic system design to create materials that have exceptional acoustic performance while being lightweight and small scale. The landscape of potential material design, enabled by our work on novel polymers and 3d printing technology, is such that we can aim to develop systems for personal audio that could constitute the science of audio of acoustic systems for the next generation of technologies in wearable consumer products.

声学超材料是一种材料，其声学特性不是源自其成分原子的特征，而是源于形状和几何形状 - 建造的方式，而不是源于建造的方式。可以以一种在传统材料中不可能的材料特性（例如负密度和负数模量）来构建这种超材料的材料 - 与我们期望材料行为的方式违反直觉的特性。这些材料中的声传播是不寻常的，并且可以使用超材料从声音中堵塞物体，以表现出极有效的噪声抑制，否则以奇怪的方式操纵声音。解决这些材料，使这些材料与现实世界中的应用更相关，是规模之一。这些结构的小型化是需要提高功效和效率的小型化，并使超材料可能可穿戴，即材料在人类努力的规模上。问题在于，通常情况下，声学系统将其小型化，远离音频频率，以及创建小型结构以启用可穿戴材料，例如耳机，具有挑战性且昂贵的制造方法正在发展，现在可以使用3D构建复杂的方法来构建您的3D构造方法，从而可以在其他方面发展，从而可以挑战性且昂贵。全球。这打开了快速原型制作小声学系统（微型乐器）的可能性，可以将它们堆叠在一起以创建声学的超材料，同时仍在音频频率下工作。在此项目中，我们试图建立具有微观功能的新的声学系统，以在音频频率中逐步构建，从而在3D系统中进行质量设计，并在3D构图中均创建材料设计，并具有材料的设计。规模。我们在新型聚合物和3D打印技术方面的工作启用了潜在材料设计的景观，以至于我们可以为个人音频开发系统，这些系统可能构成可穿戴消费产品中下一代技术的声学系统音频科学。
