'sound-focused' originates from the combination of 'sound,' meaning 'audible vibrations,' and 'focused,' meaning 'concentrated or directed attention.'

'sound' and 'focused' have been used separately in English for centuries, but their combination into 'sound-focused' is a modern development, reflecting the increasing importance of audio quality in various fields.

Initially, 'sound' referred to any noise or vibration, while 'focused' meant concentrated. Together, they now specifically refer to an emphasis on audio aspects.
