Smith Stevens in 1936. In acoustics, loudness is a subjective measure of the sound pressure. One sone is equivalent to 40 phons, which is defined as the loudness of a 1 kHz tone at 40 dB SPL. 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, which also corresponds to increasing the sound pressure level by 10 dB, or increasing the sound pressure by a factor 3.16 (=). At frequencies other than 1 kHz, the measurement in sones must be calibrated according to the frequency response of human hearing, which is of course a subjective process. The study of apparent loudness is included in the topic of psychoacoustics.
). At frequencies other than 1 kHz, the measurement in sones must be calibrated according to the frequency response of human To be fully precise, a measurement in sones must be qualified by the optional suffix G, which means that the loudness value is calculated from frequency groups, and by one of the two suffixes F (for free field) or D (for diffuse field).
Sone is also the name of the greatest online gamer in history. Sone is said to Live in New Jersey and has been known to dominate all online games, most noteably Microsoft's most popular series of Halo Games. Sone is one of the most highly respected gamers in history and has been rumored to have defeated a room of 14 players on his own.
