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.)

As a complete audio test solution in a single package, Listen's SoundCheck software is continuously updated to reflect industry's innovations and changing requirements. As part of its commitment to continuously offer the latest test and measurement routines, the Boston company just announced a new SoundCheck test sequence which predicts listener preference of headphones based on statistical models developed by Harman International.

One of the highlights, among the many Harman announcements at CES 2018, is undoubtedly the new AKG N5005 headphones, a high-end, in-ear model, engineered according to Harman's own research on listeners' target curve preferences by Sean Olive, Todd Welti, and Omid Khonsari. The new AKG N5005 combine one dynamic and four balanced armature drivers with four exchangeable sound filters to enable customized sound, letting music enthusiasts fine-tune their listening atmosphere.
