Siemens Acquires DownStream Technologies to Expand PCB Design-to-Manufacturing Flow

Siemens Digital Industries Software announced today that it has completed the acquisition of DownStream Technologies, a leading provider of manufacturing data preparation solutions for printed circuit board (PCB) design. This acquisition strengthens Siemens’ PCB design portfolio and expands its footprint in the electronics small and medium-sized business (SMB) market, and enables greater process coverage, from design to manufacturing preparation.

Simulation Techniques: Perturbation Methods in Audio Engineering

Simulation Techniques: Perturbation Methods in Audio Engineering

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.

Siemens Completes Acquisition of Altair Engineering

Altair Engineering, headquartered in Troy, Michigan is a leading name in CAE Software and product design and development solutions, also as a result of a series of key strategic acquisitions allowing the company to expand into high performance computing (HPC), data analytics, and artificial intelligence (AI). In 2024, Siemens announced the intention to acquire Altair to create the “most complete AI-powered portfolio of industrial software”.

Loudspeaker Enclosures and Technologies. Voice Coil March 2025 is Now Available

in this issue, Mike Klasco offers a renewed perspective about speaker cabinets and enclosures. Nora Wong compiled a highly sought-after Speaker Enclosure Vendors Directory for 2025. In Part 2 of his article, Dario Cinanni concludes his exploration of the SpeakerLAB software to simulate and predict speaker efficiency. In Test Bench, Vance Dickason characterizes the Dayton Audio Ultimax II 8-22 8" subwoofer and the very unique GAIT BGD-D72-64-4-0A1 glass diaphragm super tweeter.

Automotive Acoustics Analysis Using COMSOL Multiphysics. Open Webinar, January 29

The Audio Product Development Alliance (APDA) is hosting a new live webinar, this time with COMSOL, to discuss the latest developments in simulation technology for acoustic analysis of automotive environments. During the streaming event, Jinlan Huang, (Principal Applications Engineer, COMSOL) will discuss how to study the performance of a sound system and vehicle design thanks to the latest multiphysics tools now available.

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

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

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.

Design, Simulations, and Measurements in Voice Coil December 2024

Design, Simulations, and Measurements in Voice Coil December 2024

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.

COMSOL Multiphysics Version 6.3 Introduces GPU-Accelerated Acoustics Simulation

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

COMSOL Conference 2024, Boston: Acoustics Up Front

COMSOL Conference 2024, Boston: Acoustics Up Front

After a five-year gap for in-person conferences from COMSOL, the 2024 event in Boston, MA - part of a planned series now expanding to Europe (Florence, Italy) and Asia (Shanghai, China) - was a very successful return. audioXpress was invited to attend, as more and more audio developers and manufacturers use COMSOL's Acoustics Module, Structural Mechanics Module, and the AC/DC Module, among others integrated in the leading Multiphysics modeling and simulation software.
