... a scale of loudness ... (in sones) has been established for sounds ... On this scale, a given percentage change in sone value denotes an equal percentage change in the subjective loudness of the sound. The scale provides single numbers for judging the relative loudness of different acoustical environments, for evaluating the percentage reduction in noise due to various noise control measures, and for setting limits on permissible noise in factories, from motor vehicles, etc.  1, record 1, English, - scale%20of%20loudness
