Sones are useful in fields where human perception matters: audio engineering, product noise assessment, and environmental noise studies. For example, two machines producing the same dB SPL may have different sones if their spectra differ; designers use sone measures to make quieter-feeling products. In building acoustics, HVAC noise ratings often use sones to describe perceived annoyance. However, measuring sones requires psychoacoustic models or transformed measurements (from dB via equal-loudness contours), so sones are less directly measurable than dB.
