Etymology
'optical-acoustic' originates from the combination of 'optical,' derived from the Greek word 'optikos,' meaning 'of or relating to sight,' and 'acoustic,' derived from the Greek word 'akoustikos,' meaning 'of or for hearing.'
'optical' changed from the Greek word 'optikos' to the modern English word 'optical,' and 'acoustic' evolved from the Greek 'akoustikos' to the modern English 'acoustic.'
Initially, 'optical' meant 'related to sight,' and 'acoustic' meant 'related to hearing.' The combination 'optical-acoustic' now refers to phenomena involving both sight and sound.
