Parametric design of a modular acoustic volumetric unit for indoor recording spaces

Increasingly sound recording studios are demanded to host projects of different acoustic needs. However, their sonic character, effect of their contents and bulky conventional treatment solutions, usually remains unchanged. This paper reports a modular volumetric unit’s’s early-stage design,
aimed at providing usage flexibility to a group of representative recording rooms. The versatility
refers to acoustical (absorption and reflection), practical (volume and weight), and aesthetic aspects. The geometry and materials of the panel were derived parametrically through computer modelling software, by implementing interdependent and adaptable elements to one unit. Existing
recording spaces were recreated into computational acoustic models and tested in two states.
Simulations of the rooms’ acoustical behavior were run in turn, first with the original treatment, then with the panel replacing the treatment. The design goal was to have minimal differences in Reverberation Time, Early Decay Time, Clarity, Room Frequency Response for every room’s two states. Results showed the panel performing better in rooms with larger volume. Overall, the panel matched the original acoustic response and character of the rooms, while providing versatility when compared to traditional acoustic treatment solutions. The development of such a product would allow future studio users to fine tune the room’s performance according to their needs.
