Calculation of Loudness in Sones

  • John M. Eargle

Abstract

Loudness level is measured in phons, whereas loudness is measured in sones. The scale shown in Figure 137A shows the relationship between phons and sones for pure tones. Note that a loudness level of 40 dB is equivalent to 1 sone. Successive increments of 10 dB in loudness level correspond to doubling the value in sones.
