- 18:43, 29 July 2024 diff hist +663 Mathematics/Field and energy quantities (Q256) Created claim: context (P66): The confusion about "10 log" versus "20 log" is as old as sound engineering, and certainly not helped by the fact that our loudness perception is proportional to sound pressure level rather than energy. A closer look at field and energy quantities can shed light on the mystery.
