Tonality is a known indicator in the psychoacoustics field. Tonality measures the relative strength of the tones of the sound signal compared to the overall signal. This is useful to identify undesired specific tones produced by the product under test, which could be louder than the background noise produced by the product. These tones could be annoying for the user of the product, so it is part of the sound quality analysis of a product (like a hair dryer, a buzz in an electronic device, a turbine, etc). 

The LabVIEW Sound and Vibration Toolkit allows you to measure Tonality as part of the Sound Quality VIs included in the toolkit, among other sound quality indicators. 

Specifically, the VI used to get Tonality information is the SV Aures Tonality VI . It uses the Aures' Model to get Tonality information in tonality units [tu]. There are other standards to measure tonality, so it is important to consider that this is the only method that the LabVIEW Sound and Vibration Toolkit uses.
