COMSOL Conference 2025 to Kick Off in Boston, October 8-10

COMSOL announced that the first stop of its worldwide COMSOL Conference 2025 tour will be held in Boston, MA, on October 8-10. The annual COMSOL Conference provides a space for engineers, scientists, and researchers to showcase their modeling and simulation work, exchange ideas, and learn new modeling techniques. Given the recent updates in the COMSOL Acoustics module, the 2025 conference promises to be an exciting opportunity for the audio modeling and simulation community.

Standard simulations are closely tied to the analytical framework much more than the numerical. Simulation software gives insight into physical products that could not be achieved otherwise, often leading to less attention being paid to analytical methods and descriptive mathematical expressions related to the physical application. This article explores an analytical approximation method described as a perturbation approach.

In this December 2024 issue there's a new DSP product review of the Marani Pro Audio MIR260A outboard processor, and Lars Risbo shares his expertise in Numerical Optimization applied to Speaker Box Alignments. Essential resources are the updated directories of Test and Measurement and of Simulation and CAD Software vendors. On Test Bench, Vance Dickason characterizes the Faital Pro HF110 1" Neodymium Motor Compression Driver and the SB Acoustics Satori MR16TX-8 6.5" TPCD Midrange.

Multiple perspectives to inspire you in the new year. A Market Update on Bone Conduction Transducers, an article on the development of the Taction Transporter haptic transducer, and a valuable article by Hans W. Gierlich explaining an effective approach for testing structure-borne sound applied to in-ear developments. Andrew Bellavia writes about why the FDA’s OTC hearing aid rule could be quickly obsolete, Adam Levenson introduces the new Audio Foundry automotive audio development platform, and René Christensen makes its debut with audioXpress, writing about simulation techniques

COMSOL announced a major update to the COMSOL Multiphysics software version 6.0. The update builds out the Model Manager server with a web interface, adding an asset management system to make it easier for COMSOL users to manage models, simulation apps, and supplementary auxiliary files. The new COMSOL Model Manager interface combines all elements of product and process design to facilitate collaboration.

COMSOL continues its global virtual event series with COMSOL Day: Acoustics, to be held in three different time zones, with each event featuring a one-day program focusing on acoustics simulation using COMSOL Multiphysics software. Sessions will be hosted online on April 28, May 5, and May 19 by organizers in the USA, Europe, and China, respectively. Three online COMSOL Day events will showcase the benefits of multiphysics simulation to industries developing audio and acoustics products.

Branded Sound Signatures? Unique Brand Simulation Presets? All Part of Automotive OEM Engineering and Business. In this article, originally published in The Audio Voice newsletter, Roger Shively (Co-founder, JJR Acoustics) writes about automotive opportunities for branded audio and how, as audio system and vehicle acoustic simulation is on the rise, modeling and tuning of sound signatures also becomes a possibility.

MSC Software Corporation announced that it is launching a series of Acoustic Engineering Seminars throughout the United States in 2015 in order to help engineers achieve the difficult balance between government restrictions, consumer preferences, and engineering trends.
