Microphone Sets for industrial acoustic applications New approach With the unique transducer combinations G.R.A.S. is introducing a new approach to measurement microphones and to measurement data safety. By analyzing the feedback from our multi- as well as single-channel users we realized that there was a need for a different philosophy when choosing and using acoustic sensors. Daily situations where you mix up externally polarized and prepolarized microphones and preamplifiers or use wrong calibration data in the system setup are time consuming and often undiscovered until a whole set of measurement...
