We use the Sone to dB equation: dB = ×log10(Sones) + We simply insert where the ‘Sones’ are and use a handheld calculator to get the result: dB ( Sone) = ×log10() + 28 = dB. 8 Soner og sonekart. 9 Soner og sonekart. 10 The sone (/ ˈsoʊn /) is a unit of loudness, the subjective perception of sound pressure. The study of perceived loudness is included in the topic of psychoacoustics and employs methods of psychophysics. Doubling the perceived loudness doubles the sone value. Proposed by Stanley Smith Stevens in , it is not an SI unit. 11 Sones are measured on a linear scale. This means that doubling the number of sones doubles the noise level. 2 sones are twice as loud as 1 sone and 4 sones are twice as loud as 2 sones. In some ways sone noise levels are easier to understand then decibel levels. 12
