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.

For an enjoyable suggestion, after you finish reading audioXpress, Scott Dorsey reviewed an interesting book written by David Hewitt, one of the many well-known engineers who made history doing live recordings of rock concerts during the 1970s and 1980s - and continued to pioneer this approach to make great recordings of live events. On the Road: Recording the Stars in a Golden Era of Live Music, is an interesting first person testimony of some of the greatest moments in music recording history. This article was originally published in audioXpress, April 2023.

The April 2023 issue of Voice Coil reveals the genesis of Echo Test + Measurement and its AIO Test System. As scheduled, there's an updated industry directory of Cable and Connector vendors, James Croft reviews a key Polk Audio patent that expands on its Polk SDA loudspeaker prior art now in a more compact enclosure. And on Test Bench, Vance Dickason focus on the characterization of the innovative TW045WA01 dual-diaphragm tweeter from Wavecor.
