Simulation Techniques: Double Bass Arrays

Although the sound field in a room at low frequencies is one of the most discussed topics, approaches to dealing with room modes are typically treated as an optimization problem, and not correctly defined. This article explores a different strategy: the so-called Double Bass Array layout, using several subwoofers placed in a pattern, on the front and rear walls. Using advanced simulation techniques in order to understand what truly happens in the resulting room mode behavior, sound pressure levels, and resonances, this article builds upon existing research (Geddes, Welti, Devantier, et al.)
