Advancements in iterative optimization for room acoustics

This presentation introduces a palette of innovative, iterative optimization software for critical listening rooms of any size and shape. The Non-cuboid Iterative Room Optimizer (NIRO) is a pioneering tool that optimizes room geometry, listener placement, and both freestanding and soffit-mounted loudspeaker positioning for non-rectangular spaces. The Room Optimization for Cuboid Spaces (ROCS) algorithm focuses on rectangular rooms, simultaneously optimizing room dimensions and the placement of listeners and speakers. The Treatment Optimization for Room Acoustics (TORA) software is the first to determine the optimal acoustical treatment for all of the allowable architectural locations from a library of tested treatment options. Additionally, the Acoustical Treatment Calculator (ATC) is available online as a free resource to design absorption treatments. This suite of tools uses a combination of analytical calculations, wave-based and geometrical acoustics numerical methods, and optimization algorithms to improve different room acoustic metrics within the allowable architectural constraints. Examples will be presented.
