  • Loudness Units: Phons and Sones - HyperPhysics
    Using the rule of thumb for loudness, the sone scale was created to provide such a linear scale of loudness It is usually presumed that the standard range for orchestral music is about 40 to 100 phons

  • Sones and Phons - Stanford University
    At other frequencies, find the amplitude in phons by following an equal-loudness curve2over to 1 kHz and reading off the level there in dB SPL Equal-loudness curves often used (see ISO standard 226:2003) All pure tones have the same perceived loudness at the same phon level, and the dB SPL at 1 kHz defines the loudness of such tones in phons
  • PHON Definition Meaning | Merriam-Webster Medical
    The meaning of PHON is the unit of loudness on a scale beginning at zero for the faintest audible sound and corresponding to the decibel scale of sound intensity with the number of phons of a given sound being equal to the decibels of a pure 1000-hertz tone judged by the average listener to be equal in loudness to the given sound
