Use the Sound and Vibration VIs to perform sound and vibration measurements. The Sound and Vibration VIs perform the selected analysis and allow you to view the results with the appropriate engineering units in standard displays such as magnitude/phase, real/imaginary part, and decibels on/off.

The VIs on this palette can return general LabVIEW error codes or specific sound and vibration error codes.

Subpalette Description
Advanced VIs Use the Advanced VIs to perform advanced sound and vibration analysis, such as measurement analysis and condition monitoring on embedded targets that have limited computational resources.
Data Evaluation VIs Use the Data Evaluation VIs to perform limit testing on waveforms, spectra, XY data, identified peaks, or scalar measurements.
Display VIs Use the Display VIs to display signals on several types of graphs and plots.
Fault Detection VIs Use the Fault Detection VIs to perform fault detection on rotating machinery.
File I/O VIs Use the File I/O VIs to save and load dynamic signals and measurement results. Use these VIs to read data from and write data to .tdms files and UFF58 files. Use these VIs with the standard File I/O VIs and functions to add custom properties, customize a file format, and write VIs to convert between file formats.
Frequency Analysis VIs Use the Frequency Analysis VIs to perform averaged and non-averaged, or single block, frequency analysis. The analysis is based on the FFT.
Generation VIs Use the Generation VIs to generate different types of single and multitone signals, function generator signals, noise signals, and chirp signals.
Multitone VIs Use the Multitone VIs to perform multitone distortion analysis.
Octave Analysis VIs Use the Octave Analysis VIs to perform octave analysis, third-octave analysis, and fractional-octave analysis, including 1/1, 1/3, 1/6, 1/12, and 1/24 octave.
Order Analysis VIs Use the Order Analysis VIs to calculate and analyze order-related results such as spectral maps, order spectra, order magnitudes and phases, and order waveforms.
Scaling & Calibration VIs Use the Scaling & Calibration VIs to scale an input signal measured in volts to the appropriate engineering units. You also use these VIs to calibrate microphones, accelerometers, or other sensors and to measure propagation delay with DAQmx devices.
Sound Level VIs Use the Sound Level VIs to perform sound-level measurements, including linear, exponential, and peak hold averaging. Linear averaging is also known as equivalent continuous sound level, or Leq. The Sound Level VIs do not inherently perform any bandlimiting of the signal. Before the sound level is computed, the sound pressure data can be band limited through the use of analog or digital filters. All level results are returned in dB, and are RMS unless otherwise noted.
Sound Quality VIs Use the Sound Quality VIs to perform psychoacoustic measurements associated with the human perception of sound. Use these VIs to perform sound quality measurements, including stationary loudness, time-varying loudness, sharpness, roughness, fluctuation strength, and tonality. The Sound Quality VIs comply with applicable standards for use with product evaluation and as part of a comprehensive sound quality program.
Stimulus-Response Test VIs Use the Stimulus-Response Test VIs to generate reference signals and perform stimulus-response testing.
Tachometer Processing VIs Use the Tachometer Processing VIs to process analog and digital tachometer signals.
Tone and Distortion VIs Use the Tone and Distortion VIs to perform single-tone analysis and distortion measurements.
Torsional Vibration Measurement VIs Use the Torsional Vibration Measurement VIs to calculate torsional vibration signals from analog and digital tachometer signals.
Transient Analysis VIs Use the Transient Analysis VIs to perform analysis of nonstationary signals.
Vibration Level VIs Use the Vibration Level VIs to perform vibration-level measurements on time-domain and angular-domain signals.
Weighting and Filtering VIs Use the Weighting and Filtering VIs to apply a weighting filter on time-domain signals sampled at specific rates. You can choose from acoustic, telecommunication, radiocommunication, and human vibration filters.
