Array microphones are used in situations where concurrent measurements are required at several points. For example in the analyses of: sound fields, sound power, transients.

Environmental Microphones are equipped with four-pronged anti-bird spikes on top of the windscreen. This prevents birds from perching on top of the windscreen when the microphone unit is placed outdoors for long-term unattended noise surveillance.
With an installation height of less than 10 mm and thin coax wiring, the flush-mount series can be integrated into literally any design without sacrificing aero-dynamic properties.
The GRAS 146AE is a 1/2" free-field measurement microphone set for measurements in extreme environments. It is terminated with a BNC connector and is optimzed for use under rough conditions at temperatures from -40 to 125°C.
Microphone for versatile Testing. The measurement microphone set that is so rugged and well protected that it can be trusted as your standard microphone for the broadest range of automotive noise, vibration and harshness (NVH) measurements - all without compromising measurement quality.
A free-field microphone is designed to measure the sound pressure in a sound field and compensate for the influence of its presence in the sound field.
1/2" CCP Free-Field Standard SysCheck2 Microphone Set. SysCheck2TM is a new GRAS-patented technology by which the microphones is equipped with a high-precision built-in microprocessor able to generate a reference signal that enables remote verification of the entire measurement chain.
1/2" CCP Pressure Standard SysCheck2 Microphone Set. SysCheck2TM is a new GRAS-patented technology by which the microphones is equipped with a high-precision built-in microprocessor able to generate a reference signal that enables remote verification of the entire measurement chain.
The compact and lightweight Outdoor Microphone Type 4952 is suitable for long periods of unattended outdoor operation and the ideal choice for use with tNoise Monitoring Terminal (NMT) system.
Calibration is an essential step in every precision measurement. It establishes the relationship between the sound pressure and the electrical output of the microphone.
This is a ground array microphone kit designed for the aerospace industry, i.e. for measurement of noise from overhead aircraft.
CCP stands for “Constant Current Power” and describes G.R.A.S. power supplies that maintain a constant level of current for driving CCP transducers such as G.R.A.S.
