"loudness" can be measured using any units of power (energy per time). However most commonly it is measured in decibels (abbreviated dB, a logarithmic scale of power) referenced to the quietest sound a normal human can hear.
Units used to measure loudness are Sone (loudness N) and Phon (loudness level L). Scroll down to related links and look at "Loudness - Wikipedia" and "Sound level change and the change of the respective factor of volume and loudness".
it is how loud the sound is ^Smartass comment. The real answer: Loudness is determined by the intensity of sound waves.
Amplitude is the energy of a sound wave, which we also call Loudness

Loudness is affected by parameters other than sound pressure, including frequency and duration. also sound wave amplitude
The musical term that describes the loudness or softness of a sound is dynamics.
intensity :)
Volume
Amplitude of a sound wave determines LOUDNESS.
Loudness of sound is measured in decibels (dB) which quantifies the intensity or volume of a sound. Softness of sound is generally perceived subjectively and does not have a standardized unit of measurement, but is often described as quiet or faint.
The loudness or softness of a sound is its amplitude, which is the measure of the maximum displacement of a vibrating material from its resting position. A larger amplitude produces a louder sound, while a smaller amplitude results in a softer sound.
vibration remember please i'm your teacher and i know you are in wiki

The word you're looking for is "volume." Volume refers to the loudness or softness of a sound.
pleasant sound? softness and low pitch unpleasant sound? loudness and low pitch
Sound has two quantitative qualities that we usually measure and those are amplitude and frequency. So I am asuming you are referring to the loudness and softness as the amplitude quantity. The louder a sound, the more energy it carries. So, a loud sound, using your descriptive terms, has more energy than a soft sound, which has less amplitutde.
sound frequency of an individual is same . loud means high pitch. soft means low pitch
