What does loudness mean?
Loudness is the quality of being loud: the intensity, force, or prominence of a sound or, figuratively, of a person's behavior, appearance, or style. In discussions of music, speech, buildings, or neighborhood noise, it identifies how strongly a sound is perceived and may be discussed in relation to acceptable levels, complaints, or technical measurements. The word can also imply that something is excessively conspicuous, as when clothing is called loud or a performance is described as loud rather than restrained. This figurative sense carries a mild critical judgment, suggesting that a display is intended to attract attention or overwhelm the audience. Loudness is therefore more than a synonym for volume: it focuses particularly on intensity and impact, whether a sound reaches a high level or something demands notice through visual or social excess.
The quality or condition of being loud; the intensity or force of a sound.

From “loud” comes one of the clearest images in the language: sound has a measurable intensity, but “loudness” also describes anything impossible to ignore.

Where does loudness come from?
The word was formed in the 16th century by adding the suffix -ness to the adjective “loud,” which comes from Old English hlūd, meaning “loud” or “heard with ease.” The suffix -ness is a productive English suffix used to form nouns indicating a quality, state, or condition, so “loudness” came to mean the state or quality of being loud. Related forms include “loudly” and “louden,” both derived from the same adjective.
