GRAS Sound & Vibration is adding to its existing family of measurement microphones for boundary layer measurements and specifically wind tunnel testing – the new Ultra-Thin Precision (UTP) microphones. The UTP microphones - based on a patented technology - combine the high precision and reliability of GRAS measurement microphones with the need for extremely low-profiled (1 mm) microphones with minimum turbulence influence.

SoundCheck 18, the latest release of Listen, Inc.’s flagship audio test and measurement system, contains many new features focused on automation and simplicity. Some of these are specifically designed for large-scale integration in factory environments, while others are designed to accelerate R&D testing, particularly where multiple channels are required and/or voice-activated devices are being tested.

Audio Precision introduced a series of calibrated measurement microphones to its portfolio, creating a robust solution for end-to-end testing of electro-acoustic components, products and systems. This expansion of Audio Precision's electro-acoustic test offering includes free-field, pre-polarized microphones, combining mic capsules with low-noise preamplifiers, an ideal complement to the APx line of audio analyzers, software and accessories.
