'hearing-focused' originates from the combination of 'hearing,' which comes from Old English 'hēran,' meaning 'to hear,' and 'focused,' derived from Latin 'focus,' meaning 'hearth' or 'center.'

'hearing' changed from the Old English word 'hēran' and eventually became the modern English word 'hearing.' 'Focused' evolved from the Latin 'focus' through Middle French 'focuser.'

Initially, 'hearing' meant 'the act of perceiving sound,' and 'focused' meant 'centered.' Together, they evolved to mean 'concentrated on auditory information.'
