Flush-mount microphones
Our line of flush-mount sensors combines the high precision and reliability of GRAS measurement microphones with the need for very low installation height to fit the sensors into very confined spaces and narrow structures, e.g. in acoustic antennas and beams.
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. They have integrated preamplifier with plug & measure functionality, wide linear frequency range and wide dynamic range.
GRAS flush-mount microphones are among the range of special microphones that furthermore includes
