Operation and Significance
The auditory filters of enforcement machines can recode violent, insulting, antisocial, or otherwise disruptive input into meaningless environmental noise or high-decibel invalid data. This reduces the chance that verbal provocation will trigger excessive enforcement, but it also makes it difficult for human beings to influence the enforcer through pleading, negotiation, or emotion.
