Body part metaphor has long been a core research subject within the field of cognitive linguistics. Grounded on Conceptual Metaphor Theory and Embodied Cognition Theory

this thesis selects the human sensory organ "ear" as the research focus and narrows down the research scope to the semantic field of excessive speech. Based on authentic linguistic data retrieved from the Corpus of Contemporary American English (COCA) and Beijing Language and Culture University Corpus (BCC)

this paper conducts a systematic contrastive analysis of typical ear-related metaphorical expressions in English and Chinese. Representative examples include English idioms such as talk somebody's ears off

bend one's ear and chew one's ear off

as well as Chinese colloquialisms like erduo qijian (ears get calloused) and erbian feng (wind beside the ears).The research reveals that both English and Chinese construct ear metaphors on the basis of shared embodied experiences of human beings

yet their metaphorical mapping patterns differ distinctly. English tends to adopt the physical damage mapping

which conceptualizes excessive speech as tangible harm inflicted on people's ears. In contrast

Chinese favors the subjective sensory fatigue mapping

highlighting the psychological weariness brought by redundant remarks. Cultural values

interpersonal communication conventions and inherent syntactic features of the two languages collectively account for such linguistic divergences.Furthermore

this thesis explores the underlying reasons why the ear

as a passive sensory organ

has been marginalized in mainstream studies of body part metaphors. This research fills the research gap in micro-level studies of auditory metaphors

provides practical pedagogical implications for the teaching of English idioms

and offers valuable references for cross-cultural communication and translation practice.
