GRAS Begins Trade-In Campaign on Measurement Microphones

GRAS Sound & Vibration, part of Axiometrix Solutions, is implementing a trade-in offer to replace old measurement microphones with new high-quality GRAS microphones. For a limited time, any measurement microphones can be traded-in to GRAS 46AE range microphones with a 35% discount. This includes the GRAS 246AE with SysCheck2, which is a perfect combination with an Audio Precision analyzer such as APx517, or the APx1701 test interface.

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.

German company Microtech Gefell, founded in 1928 by Georg Neumann, offers one of the most complete catalogs of measurement microphones - a completely eco-system for every audio testing need. Once in a while they remember to let us know that new models are being added. This year, the company announced the MMS 212, a rugged measurement microphone combo for harsh environments and the MMS 214 model for very low sound pressure levels. Additionally, the company is now shipping the new MV 240, a measurement microphone preamplifier with an analog-to-digital converter.

While the audio industry has focused on hearables, some companies are exploring embedded wearables. Sonitus Technologies has been focusing on military communication NFMI applications, trying to embed the same features of a two-way wireless communications system that can be used undetected, even under the most harsh environments. The company's “Molar Mic” fits a miniaturized headset into a device that clips to a user’s back teeth, and is now available as a Bluetooth-compatible solution for high-noise commercial markets.

PCB Piezotronics introduced a new 1/2” (12mm) microphone and preamplifier system, for use in applications where moisture, oil splash and contamination are a concern. The new model 130A24 is a free-field, pre-polarized array microphone and preamplifier system, ideal for general purpose acoustic tests in harsh applications and environments.
