Turbulence Screen Microphones
GRAS turbulence screen microphones are among the range of special microphones that furthermore includes
Turb. att.: Up to 25 dB*
Turb. speed: Up to Mach 0.2
Freq. range (turbulence) 500 Hz - 10 kHz*
Acoustic att.: Less than 3 dB
Directivity: ± 60 Deg *Depending on flow-speed
GRAS 67TS Turbulence Screen Kit
The GRAS 67TS Turbulence Screen Kit is designed for aeroacoustic testing in solid-walled wind tunnels. The hydrodynamic component of turbulence is attenuated up to 25 dB. Thereby the acoustic signals of interest can be identified and diagnosed with a reliable resolution.
