Browse the complete list of functions and VIs available with NI Sound and Vibration Measurement Suite to learn more about how you can use this software to meet your application needs. VIs, or virtual instruments, are high-level functions in the LabVIEW environment.
The NI Sound and Vibration Measurement Suite is a comprehensive collection of NI analysis and signal processing tools for noise, vibration, and harshness (NVH); machine condition monitoring; and audio test applications. It includes the NI Sound and Vibration Assistant, which is stand-alone software for quickly acquiring, analyzing, and logging acoustic, noise, and vibration data.
The Sound and Vibration Assistant offers the ability to continually interact with live data including changing analysis settings on the fly 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 24-bit NI dynamic signal acquisition (DSA) devices, including USB DSAs, and share it easily between other commonly used sound and vibration analysis applications.
The Sound and Vibration Measurement Suite 2009 extends analysis functionality with NI LabVIEW VIs for performing continuous frequency sweeps. Using a chirp resampling algorithm, you can easily move between the time and frequency domains to extract the excitation signal. Once you have removed the excitation signal, you can conduct further analysis on the residual noise created by the device under test.
The LabVIEW VIs also contain octave analysis, frequency analysis, and order tracking for automotive, military/aerospace, and mechanical/structural designs. To further shorten the time to first measurement in LabVIEW, Express VIs for power spectra, frequency response, ANSI and IEC fractional-octave analysis, distortion measurement, order spectra, and sound quality analysis are included. 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.
You also can purchase the Sound and Vibration Measurement Suite through NI Developer Suite, a modular product offering with which you can select software components based on your application needs. With an NI Developer Suite subscription, you receive a new set of CDs featuring the most recent software version for each product in the suite four times a year as well as direct access to technical support from NI applications engineers via phone and e-mail.
Requirements for NI Sound and Vibration Measurement Suite
Same as LabVIEW Development System for Windows requirements
This measurement suite can be used stand-alone with the Sound and Vibration Assistant for customized measurement configuration. For full application development LabVIEW is required. Minimum requirements are:
