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 湍流屏蔽套件
GRAS 67TS 湍流屏蔽套件设计用于在实壁风洞中进行空气声学测试。湍流的流体动力成分被衰减达 25 dB。因此，能以可靠的分辨率识别和诊断感兴趣的声学信号。
