strident

This term describes a piercing quality that is physically uncomfortable to the ear, often evoking a sense of irritation or alarm. It is frequently used to describe high-pitched mechanical sounds or screeching voices that cut through other noises with an abrasive edge. When applied to communication or behavior, it suggests a lack of subtlety and a willingness to be confrontational. It carries a negative connotation of being overbearing or dogmatic, where the force of the delivery outweighs the logic of the argument, often leaving the listener feeling assaulted rather than persuaded.
