National Instruments sound and vibration analysis software can be used in a variety of applications including audio electronics testing; acoustic measurements; environmental noise monitoring; noise, vibration, harshness (NVH) analysis; machine condition monitoring; and rotating machinery evaluation. Signal processing functions include:

  • ANSI- and IEC-certified fractional-octave analysis
  • Power spectra, zoom FFT, FRF analysis
  • Sound level with A, B, and C weighting
  • Order analysis, order tracking, and tachometer processing
  • Orbit, Bode, Waterfall, and Cascade plots
  • THD, SNR, SINAD, and gain measurements
  • Sound quality algorithms for psychoacoustic measurement

Functions are available in interactive, configuration-based software and as National Instruments LabVIEW analysis VIs.
