GRAS Releases 6-Microphone Arrays for Automotive Cabin Acoustic Tests

GRAS Sound & Vibration, an Axiometrix Solutions company, announced the release of the GRAS PR0003 and PR0004 purpose-built microphone arrays designed to simplify in-cabin acoustic testing. With a robust structure, precise positioning tools, and two field-proven configurations, the new arrays help reduce setup time and improve measurement repeatability for accurate sound field mapping, sound tuning, NVH benchmarking, and more.

HEAD acoustics updated its ArtemiS Suite modular software platform for measuring and analyzing sound and vibration. Released a year and a half since the latest major update, ArtemiS Suite 17 improves the software with new tools, optimized workflows, and extended MATLAB integration for custom scripting and advanced automation. The update enables more accurate measurements and more efficient analysis, including in the fields of structural dynamics and transfer path analysis, hybrid modeling, and NVH development.

Every two years the Society of Automotive Engineers (SAE) holds a noise and vibration conference in Grand Rapids, MI, that is of great interest for anyone working with automotive audio. This year’s SAE Noise & Vibration Conference and Exhibition, May 12-15, proved to be equally appealing. A great content program, great discussions with the experts and valuable perspectives from noise and vibration experts.

Immersed in Audio Innovations. More than 20 demonstration cars. Record number of sponsors. Sold-out registrations for the 5th Audio Engineering Society (AES) Automotive Audio Conference at the spectacular Geely Uni3 Center, in the historic town of Gothenburg, Sweden. Roger Shively explains why the 5th International AES Conference on Automotive Audio, in Gothenburg, Sweden will be one to remember.

The next Audio Engineering Society’s biennial conference on Automotive Audio will be held in Gothenburg, Sweden, from 26-28 June. The location is the Uni3 Geely Center, right at the heart of Volvo headquarters. With the 2024 event of this popular international conference approaching, the organizing committee is reporting strong industry support and anticipation for a very strong program, and great car demos.

GRAS Sound & Vibration introduced a new microphone that can acquire good data in any sound field and, at 24 dB(A), has the lowest noise floor of any 1/4" measurement microphone. The new GRAS 46BC measurement microphone is a true multifield microphone for use in pressure, free-field, or random-incidence environments or any scenarios where the sound field is ill-defined or changing - ideal for automotive in-cabin and NVH testing.

Following immediately on the 13th Aachen Acoustics Colloquium (AAC), HEAD acoustics is hosting the exclusive User Group Meeting on the PreSense NVH Simulator, the interactive tool for virtual engineering and prototyping and a key contribution from the company towards Digital Twins. This will be a unique opportunity to help shape future developments in direct exchange with HEAD acoustics' NVH Simulator team.

Polestar 2, the new all electric car model from the exclusive brand owned by Volvo Car Group and Geely, is also betting strongly on distinct interiors and a focus on the whole audio experience. The Polestar 2 features a premium Harman Kardon audio system developed by Harman uniquely for the car, and allows over-the-air (OTA) updates to introduce new and improved audio features and functions over time. And being a Swedish brand, Polestar 2 also features Spotify Group Sessions Beta directly in its built-in Spotify app.
