Sound is an integral aspect of architectural experience and of building performance. However, despite sound's importance and the existence of applicable design methods in acoustic engineering, sound is rarely considered in the architectural design process. In the past decades, the architect's design tools have substantially changed: the architectural drawing has gone from paper to digital, from 2-D to 3-D, parametric and computational methods now enable the realisation of buildings with complex geometry, and computer simulation can now evaluate aspects of design that were previously not possible. Designers and engineers are now beginning to design for sound using parametric design, computer simulation, and digital fabrication.*******This research seeks to radically and creatively integrate sound into the architectural design process, and test these new processes through the production of novel acoustic surfaces. With a particular focus on everyday spaces such as meeting rooms, lecture halls, and open plan working environments, the experiments utilize computational design algorithms and parametric modelling techniques, combining these with established and custom simulation software to create acoustically performance-driven spaces and surfaces. The research objectives are: to develop digital design tools and link these to computer acoustic performance evaluation: to study the potential of digital fabrication for the production of acoustically performance-driven architecture: to investigate the relationship of the placement of different types of acoustic surfaces and the resulting acoustic characteristics of the space: to study the amount of sound scattering that is necessary to achieve good acoustic performance; and, to develop design techniques and find acoustic parameters to define perceptible subspaces of acoustic performance created by varying material properties of surfaces within an open-plan space.*******Scientific methods for acoustic simulation and auralization will be used to evaluate digital design proposals and established quantitative measurement methods will be used to evaluate 1:1 prototypes. While the linking of design and evaluation is essential, this research proposes that this is insufficient. Architecture is a design process that extends from ideation through to realization, and so the incorporation of acoustic performance must be integrated not only in design and simulation but also into the construction logic of fabrication and assembly. This research will result in the production of novel design methods and digital fabrication techniques in creating new acoustic surfaces. These new design methods will specifically benefit Canadian architects and engineers enabling them better engage with sound, and the development of new acoustic surfaces will generally benefit Canadians and result in better sounding buildings.*********

声音是建筑体验和建筑性能的一个组成部分。然而，尽管声音的重要性和声学工程中适用的设计方法的存在，声音很少被考虑在建筑设计过程中。在过去的几十年里，建筑师的设计工具发生了巨大的变化：建筑图纸已经从纸质到数字，从2-D到3-D，参数化和计算方法现在可以实现具有复杂几何形状的建筑物，计算机模拟现在可以评估以前不可能的设计方面。设计师和工程师现在开始使用参数设计、计算机模拟和数字制造来设计声音。这项研究旨在从根本上创造性地将声音融入建筑设计过程，并通过生产新颖的声学表面来测试这些新的过程。特别关注会议室，演讲霍尔斯和开放式工作环境等日常空间，实验利用计算设计算法和参数建模技术，将这些与已建立和定制的模拟软件相结合，以创建声学性能驱动的空间和表面。研究目标是：开发数字设计工具，并将其与计算机声学性能评估联系起来：研究数字制造在生产声学性能驱动的建筑方面的潜力;研究不同类型声学表面的放置与所产生的空间声学特性之间的关系;研究实现良好声学性能所需的声音散射量;开发设计技术并找到声学参数，以定义通过改变开放式空间内表面的材料特性而产生的声学性能的可感知子空间。声学模拟和可听化的科学方法将用于评估数字化设计方案，而既定的定量测量方法将用于评估1：1原型。虽然设计和评估的联系是必不可少的，但本研究认为这是不够的。建筑是一个从构思到实现的设计过程，因此声学性能的结合不仅必须集成在设计和仿真中，而且还必须集成到制造和装配的构造逻辑中。这项研究将导致生产新的设计方法和数字制造技术，创造新的声学表面。这些新的设计方法将特别有利于加拿大建筑师和工程师，使他们能够更好地参与声音，新的声学表面的发展将普遍有利于加拿大人，并导致更好的声音建筑。
