Development & Design: Experimental and Theoretical Investigation of an Unusually Shaped Horn

In another example of cutting-edge experiments that deserve recognition, Joerg Panzer (R&D TEAM, Germany) and Patrick Macey (PACSYS, UK) detail an investigation of the sound pressure response and radiation impedance of a loudspeaker horn driven by an electro-dynamic transducer. The two authors (and creators of the respective software tools) combined measurements with simulation software using finite and boundary element methods and explored the associated issues with meshing for each method.

Speaker Builder: Open-Baffle Subwoofer Simulation with Akabak

Confronted with the impossibility to conduct reliable measurements in the low-frequency domain for his DIY speaker project, George Ntanavaras explores the alternative of relying solely on simulation software. To validate the design of an open-baffle subwoofer using the AKABAK software, created by German company R&D Team, he also explores the transition from measurements to simulation. His experiments contrast the near-field response measurements of his loudspeaker with the accuracy of the simulation using AKABAK.

COMSOL Multiphysics Version 6.3 Introduces GPU-Accelerated Acoustics Simulation

COMSOL continues to expand the possibilities for simulation of real-world designs, devices, and processes, and now announced Version 6.3 of its COMSOL Multiphysics software. As largely anticipated in the recent series of conferences, COMSOL 6.3 introduces a new Electric Discharge Module, GPU-accelerated simulations, and many other updates. The Acoustics Module now offers GPU support for transient pressure acoustics, porous materials in the time domain, SLNS formulation for thermoviscous acoustics, anisotropic poroacoustics, and much more

Holoplot and AFMG Implement X1 and X2 Matrix Array In EASE 5

The inclusion of Holoplot products in the latest EASE 5 update, will allow users to investigate the possibilities and impact of using Matrix Arrays in any venue. Users of the popular electro- and room acoustic simulation software can now model Matrix Arrays and Beam Optimizations in the company's Plan system design software to view sound pressure level simulations. The resulting array configurations can now be exported to EASE 5 for further analysis based on closed-room simulation.
