  "y_long_desc": "The decibel (dB) is a unit of measurement derived from the bel, representing one-tenth of a bel. It is widely used in acoustics, electronics, and telecommunications to express the ratio of power, intensity, or amplitude. Decibels provide a convenient way to compare different levels on a logarithmic scale, making them essential for measuring sound levels, signal strengths, and other quantities that vary over a wide range. The decibel scale is used in everyday contexts, from determining the volume of music to assessing noise pollution.",
  "x_long_desc": "The neper (Np) is a logarithmic unit of measurement used to express ratios of measurements such as voltage, current, or power, especially in fields like telecommunications and electrical engineering. Unlike the decibel, which is based on a logarithm to the base 10, the neper is based on natural logarithms (base e). Nepers are particularly useful in contexts where continuous signals or natural exponential growths are involved. They provide a clear understanding of signal attenuation and amplification in various engineering applications."
