What does boisterousness mean?
Boisterousness is an English noun denoting the quality of being noisy, energetic, and rough or exuberant in behaviour. It is derived from the adjective "boisterous," which has described loud, stormy, or rowdy conduct since the sixteenth century, originally evoking the violence of wind and sea before settling into everyday use for lively human behaviour. The word is typically applied to people — especially children, crowds, parties, and celebrations — whose high spirits produce a level of noise or commotion noticeable to others. Its connotation is flexible: it can carry mild disapproval when the noise is unwelcome or disruptive, yet it can also be used warmly or even admiringly to describe cheerful, good-natured liveliness at a festival or family gathering. Writers reach for it when they want a single term capturing not merely volume, but the combination of noise, energy, and uncontrolled enthusiasm. It is a somewhat literary choice, more likely to appear in descriptive prose than casual speech, where simpler terms like "rowdiness" might be preferred.

Etymology of boisterousness
Boisterousness is formed from "boisterous," an adjective attested from the late fifteenth to early sixteenth century, plus the noun-forming suffix "-ness." The origin of "boisterous" itself is uncertain: it is generally thought to be a Middle English formation possibly influenced by Old French "bourdeux" (meaning coarse or rustic) or related to words meaning swollen or puffed up. Early uses described violent weather — storms and rough seas — before the word came to describe noisy human behaviour by the seventeenth century. There are no close foreign cognates; the word's relatives are chiefly its own derivatives within English.
