Overview
The NI Sound and Vibration Toolkit includes a collection of VIs that you can use to perform typical measurements for audio, acoustic, or vibration applications. The Sound and Vibration Toolkit also includes the NI Sound and Vibration Assistant. The NI Sound and Vibration Measurement Suite provides order analysis functionality for the Sound and Vibration Assistant and LabVIEW in addition to the Sound and Vibration Toolkit. The Sound and Vibration Measurement Suite also provides additional functionality in LabVIEW such as human vibration filters, torsional vibration measurement VIs, and custom displays.
Use the Sound and Vibration Toolkit or the Sound and Vibration Measurement Suite to perform the following sound and vibration measurements:
Scaling a signal to engineering units
Calibrating a measurement channel
Applying weighting filters
Integrating time-domain signals
Performing level measurements
Performing fractional-octave analysis
Performing frequency analysis
Performing single-tone measurements
Performing distortion analysis
Performing swept-sine measurements

New Features
The Sound and Vibration Measurement Suite includes the following new features in LabVIEW.
Measuring Torsional Vibration
Torsional vibration is a common phenomenon for rotating machinery such as engines, compressors, and turbines. High torsional vibration in a rotating system can cause the failure of rotating components or damage to the system. Use the Torsional Vibration Measurement VIs to measure and monitor torsional vibration in rotating systems. The Torsional Vibration Measurement VIs can calculate torsional vibration signals from both analog and digital tachometer signals. The Torsional Vibration Measurement VIs also can compensate for geometric imperfections that a tachometer system might have.
Applying Weighting to Human Vibration Signals
Human vibration refers to the effects of mechanical vibration on the human body. Measuring and analyzing human vibration signals can help control the negative effects of mechanical vibration on the human body. Use the SVT Human Vibration Weighting Filter (Fixed Rate) VI, the SVT Human Vibration Weighting Filter (frequency) VI, and the SVT Human Vibration Weighting Filter (octave) VI to apply weighting to human vibration signals in both the time and frequency domains. Applying weighting to human vibration signals can isolate the directional components that you are interested in and help you further analyze different types of human vibration.
Performing Order Analysis on VxWorks Real-Time Targets
The Sound and Vibration Measurement Suite now supports order analysis functionality on VxWorks Real-Time targets.
