Evolutionary Computational Design for Spatial Acoustics
Architectural Form Generation of Acoustic Spaces Employing Evolutionary Design Algorithms Based on Space-morphological and Material Parameters

Designing acoustic spaces such as concert halls and theatres is a challenging task. Spatial acoustics need to be considered as a complex system of geometry, materiality and human perception. Due to this complexity, in current practice the design of acoustic spaces is typically based on a small number of acoustic space-typologies with proven performance.

The research is focusing on an alternative approach to develop spatial concepts for acoustic rooms. This approach synchronously considers both geometric and material parameters that are critical for the acoustic performance in one integrative computational design process. A universal synthesis algorithm generates individual tessellated spatial envelopes with assigned material characteristics. Through a robust genetic evolutionary search algorithm the domain of valid individuals is explored and algorithmically evaluated based on acoustical and space-morphological criteria.
