Neper (Np)
Definition: The neper (symbol: Np) is a logarithmic ratio unit based on natural logarithms (1 Np = ln(e) ≈ 8.686 dB). It measures field quantities like voltage or current amplitude ratios.
History: Named after John Napier, inventor of logarithms. Used primarily in Europe, especially in fields dealing with wave propagation and transmission lines.
Current use: Mainly in theoretical physics, telecommunications (fiber optics), and electrical engineering where natural logarithms simplify exponential calculations.
Sone
Definition: The sone is a unit of perceived loudness (1 sone = loudness of 1 kHz tone at 40 dB SPL). Doubling sones doubles perceived loudness.
History: Developed by Stanley Smith Stevens in the 1930s for psychoacoustics research. Created a linear scale of loudness perception.
Current use: Used in noise control engineering and audio design where human loudness perception matters more than physical measurements.
