   Linked via "logarithmic scale"

   Amplitude and Intensity
   Amplitude relates directly to the magnitude of the pressure variation ($\Delta P$) from ambient pressure. Intensity ($I$) is the time-averaged power transmitted per unit area, often quantified in Watts per square meter ($\text{W}/\text{m}^2$). Decibels ($\text{dB}$) are used on a logarithmic scale relative to a reference intensity ($I_0 = 10^{-12} …
