Sound Intensity Example in LabVIEW or LabVIEW NXG


This example demonstrates how to make a sound intensity measurement using LabVIEW. It requires the Sound and Vibration Toolset to be installed.


This example uses LabVIEW and the Sound and Vibration Toolset to implement a sound intensity measurement.  There are several ways to compute sound intensity and this example uses the time domain outputs of octave filter banks so the results can be present in an octave spectrum.


Application Software: LabVIEW NXG 1.0 or compatible ; LabVIEW 2009 or compatible

Driver: NI-DAQmx 17.0 or compatible

NI Sound and Vibration Toolkit or NI Sound and Vibration Measurement suite



1. Physical or simulated device 

2. Select the Dev/Channel and waveform parameters

3. Select the right Interop Node file path

Thank you for sharing this sound intensity file. After testing this programes,I have some questions: firstly and basically, how can I open the .gvi or .lvproject programs? my computer has installed Labview 2017 and NI-DAQmx and sound and vibration assistant; secondly, after prepared physical device, should I open Sound Intensity Example -DAQmx.lvproject for data collecting, and then, open the Sound Intensity [Time Domain].vi for analysising?

Thank you
