Meaning: This idiom is used to describe a situation where someone’s words, advice, or appeals are ignored or disregarded by others, particularly when attempting to communicate important information or express concerns. It implies that the intended message fails to evoke a response or consideration from the recipient, as if they were unable or unwilling to hear or understand it.

Origin: The origin of the idiom “fall on deaf ears” is rooted in the literal sense of being unable to hear due to deafness.

It emphasizes the frustration and futility of trying to convey important information or concerns to individuals or groups who are unresponsive or unwilling to listen.
