Quick Answer
Unheard can mean not heard, ignored, unknown, or unprecedented. Useful alternatives include inaudible, unnoticed, ignored, unknown, and unprecedented.
A quiet sound, an ignored complaint, or a remarkable event can all make you reach for the word unheard. The difficulty is that this word has several meanings, so one replacement does not work in every sentence.
The phrase synonym of unheard can therefore lead to different answers depending on context. A sound may be inaudible, while an overlooked opinion may be ignored or unacknowledged. When something has never happened before, unprecedented is usually a better choice.
