National Instruments sound and vibration analysis software, including the NI Sound and Vibration Measurement Suite and the NI Sound and Vibration Toolkit, provides signal processing functionality for performing audio measurements, fractional-octave analysis, frequency analysis, transient analysis, and order tracking. NI sound and vibration analysis software features NI Sound and Vibration Assistant, an interactive software for quickly acquiring, analyzing, and logging acoustic, noise, and vibration data. With a configuration-based, flexible measurement library and open-analysis capability, Sound and Vibration Assistant is designed for quick data capture through a unique software-based measurement approach to create customized applications.
Sound and Vibration Assistant
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 National Instruments 24-bit dynamic signal acquisition (DSA) devices, including low-cost, USB DSA devices, and share the data easily between 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 National Instruments 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 colormap processing are included to shorten time to first measurement in NI 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, National Instruments 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.
