吵 (chǎo) is a word that works as both an adjective meaning 'noisy / loud' and a verb meaning 'to quarrel' or 'to disturb with noise.'
As an adjective it describes an environment full of unpleasant sound: 这里太吵 ('it's too noisy here'). As a verb it means to bicker or argue loudly (吵架 = to have a quarrel) or to bother someone with noise (别吵我 = 'don't disturb me'). The mouth radical 口 signals it is about sound coming from mouths.
Two differences from English: 吵 as an adjective needs no 'is' verb — 太吵了 stands alone as 'too noisy'; and the same single character covers both 'noise' and 'quarrelling,' which English splits into separate words. When it means quarrel, it usually takes 架 (吵架) or an object; when it means noisy, it stays adjectival.

闹 also means noisy/rowdy but implies commotion or fuss (热闹 lively, 吵闹 clamorous). 吵 leans toward unpleasant, disturbing noise or verbal quarrelling. 闹 can be festive; 吵 rarely is.
喧闹 is a more written, descriptive word for a boisterous, clamorous scene. 吵 is the plain spoken word you use in daily complaints about noise.
炒 (fire radical 火) means 'to stir-fry,' as in 炒饭 (fried rice). 吵 (mouth radical 口) means noisy/quarrel. Same pinyin and tone, different radical and meaning.
闹 can mean lively or to make trouble; it is not always negative. 吵 specifically means disturbing noise or a verbal fight.
