Why do people want to measure the temperature? To tell a number for what they are subjectively feeling - and to tell if it is too hot or too cold Why do people want to measure the loudness of a sound? To tell a number for what they are subjectively hearing - and to tell if it is too loud, but never if it is too soft. The subjective loudness is not measurable. Instead we mostly measure the objective sound pressure in pascals or the sound pressure level SPL in dB, or in dbA if there are weighting filters.
