Low Noise Microphone

Low Noise Microphone

Low Noise Microphone

MMS 214

Low noise microphone MMS 214 has a particularly low inherent noise level and is designed for acoustic measurements of low sound pressure levels close to the threshold of human hearing. 

The electrical connection is via a BNC cable to devices with IEPE supply. 

The microphone preamplifier internally generates the polarization voltage for the externally polarized microphone capsule. 

The measurement microphone is equipped with a build-in memory for microphone identification (TEDS acc. IEEE 1451).

  • Sensitivity: 320 mV/Pa
  • Free-field
  • 2 Hz to 20 kHz
  • 6.5 dBA to 104 dB
  • IEPE (BNC)
  • Microphone power supply: IEPE
  • Class 1 – WS2F – IEC 61094-4
  • TEDS acc IEEE 1451

Spectrum Analyzer - Measurement Microphone Software

I would like to take this opportunity to provide a brief introduction to the ARTA software, which includes Plug.n.DAQ Lite MMS 214 Low Noise Microphone and Microphone Calibrator. 

In this demonstration, I will be showing the calibration of the measurement chain.

FFT Analyser Freeware

If you are looking for a FFT analysis software that will allow you to turn your PC into a full-featured measurement instrumentation, Visual Analyzer is the right tool for you!

The best part is that there is no need to install any additional or new hardware. 

You can simply use the sound card in your PC to start measuring sound.

With the Visual Analyzer, it is now even easier to analyze sound signals.

Besides, you don’t have to worry about licensing, since the program is already available for everyone.
