The sone was proposed by Stanley Smith Stevens as a unit of perceived loudness in 1936. Loudness is the subjective perception of sound pressure. According to Stevens' definition, the sone is equivalent to 40 phons, which is defined as the loudness level of a 1 kHz tone at 40 dBSPL. The number of sones to a phon was chosen so that a doubling of the number of sones sounds to the human ear like a doubling of the loudness.
To convert sone to decibel, you can use the formula: Decibels (dB) = 40 log(sone) For example, if the loudness level is 4 sones, the equivalent decibel level would be 40 log(4) ≈ 60 dB.
The sound level in decibels (dB) required for a 1 sone loudness at a frequency of 50 Hz would be around 40 dB. This is because 1 sone is approximately equal to 40 phons, and for a 50 Hz tone, 40 phons is equivalent to around 40 dB SPL (Sound Pressure Level).
The psychoacoustic loudness N is measured in sones. The loudness level (Volume) LN is measured in phons. Scroll down to related links and look at "Conversion of sone to phon and the problem with dBA".
Units used to measure loudness are Sone (loudness N) and Phon (loudness level L). 40 Phons = 1 Sone. Scroll down to related links and look at "Loudness - Wikipedia" and "Sound level change and the change of the respective factor of volume and loudness"
The unit of perceived loudness equal to 40 phons is 40 decibels (dB). Decibels are commonly used to measure the intensity of sound, with 40 dB typically considered as a moderate level of loudness.

Low sone is quieter than high sone. Sone is a unit that measures the perceived loudness of a sound, so a lower sone rating corresponds to a quieter sound.
In Japanese, "sone" (ソネ) does not have a widely recognized or specific meaning, as it is not a common word in the language. However, it could be a name or part of a larger phrase. In different contexts, "sone" might also refer to a specific term in certain dialects or fields. If you meant "sone" as a phonetic representation, it may be helpful to clarify the context for a more accurate interpretation.
