The kanji 騒 is a phono-semantic compound (形声文字, けいせいいもじ). It's composed of two parts: the radical 口 (くち, kuchi) meaning "mouth" or "speech," on the left side and the phonetic component 蚤 (そう, sou) on the right side. 蚤 (そう) originally meant "flea" but here it contributes to the sound and suggests the idea of small, quickly moving things, therefore, implying a sense of restlessness or agitation, adding to the meaning of "noise" or "disturbance." The combination of 口 with 蚤 creates a character representing a situation of many mouths, hence a lot of noise.
