National Instruments sound and vibration software provides a complete software solution for all acoustic; electroacoustic; noise, vibration, and harshness (NVH); and machine condition monitoring applications. Based on an open analysis capability and a flexible measurement library, the NI Sound and Vibration Measurement Suite and NI Sound and Vibration Toolkit present a unique software-based measurement approach to creating customized applications.
For a more complete comparison, refer to the Sound and Vibration Software Overview and Comparison below.
Sound and Vibration Assistant
The Sound and Vibration Assistant offers the ability to continually interact with live data to modify analysis settings dynamically while logging data to disk for more analysis later. For example, you can vary the weighting and bandwidth of an octave spectrum while recording sound level data or adjust the window applied to a power spectrum while trending overall vibration readings. With Universal File Format (UFF58) file I/O support, you can acquire data from NI 24-bit dynamic signal acquisition (DSA) devices, including low-cost, USB DSA devices, and share the data easily among other commonly used sound and vibration analysis applications including modal analysis software.LabVIEW Analysis VIs and Displays
The Sound and Vibration Measurement Suite contains the most comprehensive collection of NI LabVIEW analysis VIs for noise, vibration, and harshness; machine condition monitoring; and audio test applications. Express VIs for power spectra, frequency response, ANSI and IEC fractional octave analysis, distortion measurement, order spectra, and color map processing are included to shorten time to first measurement in LabVIEW. You can quickly and efficiently begin applications with more than 50 ready-to-run LabVIEW example code bases provided in the Sound and Vibration Measurement Suite.Recommended Hardware
For sound and vibration data acquisition, NI recommends DSA devices. With 24-bit ADCs and DACs, integrated antialiasing filters, and IEPE conditioning for microphones and accelerometers, NI DSA devices are designed for acoustic and vibration measurements.
