Generative Approaches to Low-Frequency Optimization in Control Rooms
* Presenting author
Abstract:
The acoustic optimization of control rooms is essential to create ideal conditions for music recording and mixing. Helmholtz resonators are particularly effective in the low-frequency range, reducing modal effects and controlling reverberation time. Traditionally, analytical approximations are used to select suitable commercial resonators. However, a generative approach enables precise, room-specific optimization of key resonator parameters, such as porous material thickness, perforation size, wall distance, and positioning within the room, to achieve a near-constant frequency response below the Schroeder frequency. This tailored approach, combining FEM-based sound field calculations with an evolutionary algorithm, ensures highly effective frequency response optimization. The implementation, advantages, and limitations of this generative method are discussed.
