'hearing-centered' originates from the combination of 'hearing,' which comes from Old English 'hēran,' meaning 'to perceive by the ear,' and 'centered,' derived from Latin 'centrum,' meaning 'center.'

'hearing' changed from the Old English word 'hēran' and eventually became the modern English word 'hearing.' 'Centered' evolved from the Latin 'centrum' through Old French 'centre' and Middle English 'centre.'

Initially, 'hearing' meant 'to perceive by the ear,' and 'centered' meant 'placed in the center.' Over time, 'hearing-centered' evolved to mean 'focused on auditory processes.'
