acoustic
uh-KOO-stik
/əˈkuː.stɪk/
Relating to sound, hearing, or the physical properties of sound waves; designed to operate without electronic amplification.
Refers either to the physical science of sound propagation or to natural, unamplified musical instruments.
The story behind the word. The word traces back to ancient Greek 'akoustikos', meaning 'pertaining to hearing', derived from 'akouein', to hear. It passed into French as 'acoustique' before entering 17th-century English as natural philosophers began systematically studying sound wave behavior in physical spaces.
