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.)

Simulation Techniques: Acoustical Shape Optimization for Vibroacoustics Applications

Having detailed how formal optimization can be used for product design of audio products such as speakerphones and waveguides, in this article René Christensen explores free-form and alternative optimization techniques where the topology of the geometry is given from the outset. Using practical examples, this article addresses shape optimization techniques, identifying useful types of boundaries and challenges to look out for audio product designs. This article was originally published in audioXpress, February 2024.

Technische Universität Berlin and AFMG Publish High-Resolution EASE GLL Data for 22 Musical Instruments

Ahnert Feistel Media Group (AFMG) in cooperation with the Audio Communications department of the Technische Universität Berlin, has recently published a set of high-resolution GLL datasets for 22 musical instruments for use in EASE 5 First Edition! The data is the result of a major project which was realized by the research group that took several years to complete. Numerous musicians have been recorded playing their instruments in an anechoic chamber using a purpose-designed spherical microphone array.
