Simulation Techniques: Acoustic Topology Optimization for Vibroacoustics Applications

Acoustic topology optimization is one of the most interesting new technologies in vibroacoustics. These powerful tools enable engineers to find optimal solutions to problems related to their specific applications and this article presents multiple examples in different areas. The article, originally published in audioXpress, April 2023, includes several examples of transducer geometries modified via acoustic topology optimization.

The March 2022 issue of Voice Coil offers a complete overview of loudspeaker cabinet design options, plastic enclosure materials, and production techniques, as well as an updated directory of Speaker Enclosure Vendors. This month, in Test Bench, Vance Dickason characterizes the Mundorf U80W from its latest U Series of Air Motion Transformers. And addressing demanding professional audio applications, this issue also includes a Test Bench on Eighteen Sound’s NSD1095N Compression Driver and XT120 Horn. Start reading online.
