clamour, uproar, annoyance
訬 centers on noisy, agitated disturbance: clamour, uproar, or the annoyance that such noise causes.
訬 combines 言 (speech) with 少, which likely contributes the sound and may suggest small, sharp, or agitated speech, leading to the idea of clamour or uproar.
Words (言) that are small (少) in substance but loud in delivery create clamour and annoyance.
For ソウ, imagine the uproar of a crowd sounding like a loud 'sow!' (as in a female pig) — the noise is so annoying it echoes ソウ.
