SimAUD 2020.https://hdl.handle.net/1805/28290This paper broadens the scope of on-going research that introduces rule-based methods for designing creative acoustic arrays: from single-frequency QRD-based panels to those which account for multiple design parameters such as frequency, absorption, and number of wells. Expanded parameters create more complex arrays that give acousticians a finely tuned and intentional acoustical response as it relates to these input rules. Numerical simulations show three-dimensional directivity responses for these shape grammar generated diffuser arrays. A visual complexity coefficient is presented to quantify the aesthetic component to designs of arrays of acoustic panels. Along with spatial simulated diffusion response, diffusion coefficients, and the visual complexity coefficient, designers and acousticians will be afforded ways to create both acoustical effective and visually interesting arrays.enPublisher Policyarchitectural acousticsacoustic simulationSchroeder diffuser arraysArticle
