Here are the definitions for the most likely meanings:
The calculation of sone involves complex auditory perception models, taking into account the frequency and intensity of sound. For pure tones, the relationship between loudness in sones and sound pressure level in decibels can be relatively straightforward. However, for complex sounds, such as those encountered in everyday life (e.g., traffic noise, music), the calculation becomes more complicated due to the need to consider the sound's spectral characteristics and how different frequencies contribute to the overall perceived loudness. sone definition
Future research and developments aim to refine the definition and application of the sone, incorporating advances in psychoacoustics and signal processing. The integration of sone measurements with other metrics, such as the Equivalent Continuous Sound Level (Leq) and the A-weighted decibel (dBA), could provide a more comprehensive understanding of noise exposure and its effects on human health.

One sone is defined as the loudness of a 1,000-hertz pure tone at a sound pressure level of 40 decibels (dB).
The sone is used in fields where human perception of sound matters more than physical intensity:
