Abstract
A visual language for designs of acoustical arrays is defined by a shape grammar that deploys design rules using shape representations of acoustic panels with labels and weights to specify known formal and performative information. Reciprocal 3-D acoustic plots are computationally simulated using a perfectly matched layer finite element method and inform how the interactions of invisible sound waves are impacted by visual design decisions. This paper presents the results of this framework with 3 × 3 arrays of diffusers and absorbers, resulting in the introduction of an aesthetic value \(~\bar{E}\), incorporated with the diffusion coefficient, allowing for nuanced objective performative evaluation of these arrays. This ultimately leads to creative visual expressions of design rooted in acoustic theory and performance.
