Launched December 15, 2021, the new COMSOL 6.0 software introduced a simplified workflow for setting up hybrid lumped-FEM models of loudspeakers, a user interface for the simulation of magneto-mechanical forces in transducers, and much more. This will be a unique opportunity to learn about these and other new features in the updated COMSOL Acoustics Module, reflecting in great part from feedback collected from users within the audio industry.
The Modeling and Measurement events promoted by the Audio Product Education Institute are sponsored by COMSOL, and as such the AESA/APEI has planned an opportunity for the audio industry to get familiar with the new possibilities and also ask the questions that relate to electroacoustic transducer applications.
With the audio industry increasingly initiating new product development efforts with simulation-driven designs, and progressing gradually to Digital Twins, it becomes important to understand all the vast possibilities these tools can offer. Using modeling and simulation systematically through the design and optimization stages of an acoustic device, is proving to enable significant performance breakthroughs. Not only by removing variables, but by identifying key undesired properties and effects, while enabling practical solutions that can be prototyped, verified and implemented.
The Acoustics Module in COMSOL Multiphysics 6 introduces many highly requested features that reflect the software's increasing use in the audio industry. The session will provide an overview of those important areas of improvement, such as the possibility to model piezoelectric phenomena in the time domain for wave propagation using a time-explicit formulation, physics-controlled mesh for pressure acoustics problems, or new high-frequency wave methods. Speaker designers in particular can benefit from a new Lumped Loudspeaker boundary condition and sector symmetry options in the exterior field.
This event will benefit from the participation of Roger Shively (JJR Acoustics, LLC), highly experienced in the areas of transducers, automotive audio, psychoacoustics, and computer modeling, and Tim Whitwell (Tectonic Audio Labs) which currently leads cutting-edge efforts in transducer development using COMSOL. Roger will share his experience and ask questions, while Tim will discuss his work with the new software, and modeling external pressure fields using the new cyclic symmetry feature. The session will be open for questions following presentations.
The Audio Product Education Institute’s Modeling and Measurement education pillar is sponsored by COMSOL and underscores the AES’s commitment to providing its membership and the industry at large with information on real-world solutions for audio product development.
