boisterous, make noise, clamor, disturb, excite
騒 centers on loud, restless activity that disturbs the peace: boisterous noise, clamor, or excited agitation.
騒 is the modern simplified form of 騷. The older form combines 馬 (horse) with 蚤 (flea), suggesting the restless, noisy agitation of a horse bothered by fleas. The modern right side is a simplification.
A horse 馬 with a flea-like irritation on its right side: imagine a horse stomping and whinnying noisily, creating a boisterous disturbance.
For ソウ, picture the noisy horse making such a racket that it sounds like a whole soul band warming up: soul -> ソウ, and the clamor fills the stable.
