Measurement Microphones

National Instruments has announced that NI Alliance Partner G.R.A.S. Sound & Vibration, a leading producer of acoustic front-end products, now sells microphone kits for use with NI dynamic signal acquisition (DSA) hardware. NI offers several different microphone types, from array microphones to condenser microphones appropriate for class 1 sound-level measurements. Customers in a number of industries, including aerospace and defence, are already having success using these products for applications like acoustic holography, environmental noise, noise mapping and sound power.

“For more than 10 years G.R.A.S. and NI have worked together on joint projects, and there has always been a great collaboration between our companies,” said Peter Wulf-Andersen, Managing director at G.R.A.S. Sound & Vibration. “I am proud that one of the biggest players in the industry has chosen G.R.A.S. as an official partner.”

NI’s new microphone kits include a G.R.A.S. microphone capsule and preamplifier. Inside the capsule is a diaphragm made of a special stainless alloy that provides maximum sensor life. The microphones contain a Transducer Electronic Data Sheet (TEDS) chip and combine with NI DSA hardware to provide a plug-and-play sensor experience.
