Pronunciation

  • 5th-century BC Attic: /a.kuːs.ti.kós/[1]
  • 4th-century AD Koine: /a.kus.tiˈkos/[1]
  • 10th-century Byzantine: /a.kus.tiˈkos/[1]

Forms

ᾰ̓κουστῐκός (akoustikós) m (feminine ᾰ̓κουστῐκή, neuter ᾰ̓κουστῐκόν); first/second declension[1]

Etymology

It is formed from Ancient Greek ἀκουστός (akoustós, “heard, audible”) + -ικός (-ikós),[2][3] the verbal adjective of ἀκούω (akoúō, “to hear”).[3] Wiktionary derives it directly from the verb with the suffix.[1]

Earliest recorded meaning

It first appears in Aristotle, who calls the faculty of hearing τὸ ἀκουστικόν in On the Soul and uses the adjective of a person ready to listen in the Nicomachean Ethics.[4][5][6]

Semantic evolution

Later philosophers and physicians used it of hearing in general: Epicurus speaks of the experience of hearing, Plutarch of the sense of hearing, Epictetus in Arrian of the faculty of hearing, and Galen calls the ear canal the “acoustic passage”.[4][5] Iamblichus counts being silent and good listeners among the qualities of the Pythagoreans, and Aulus Gellius uses it for the lower grade of Pythagorean pupils, otherwise called ἀκουσματικός (akousmatikós).[5][4] A scholiast on Euripides uses it in the sense “audible”.[5]

Modern Greek ακουστικός (akoustikós) is a learned revival of the Hellenistic word, with sense influence from French acoustique.[7] Its feminine and neuter became nouns, ακουστική (akoustikí) “acoustics” and ακουστικό (akoustikó) “receiver, earphone”.[2] The English word acoustic (about 1600) comes from the French word, from the Latinized form of the Greek word.[3]

Timeline

  • 4th century BC – Aristotle uses it of the faculty of hearing and of people disposed to listen.[4][5]
  • 1st century BC – Philodemus uses the adverb of pleasure taken through hearing.[5]
  • 2nd century AD – Galen names the ear canal with it, and Aulus Gellius uses it for a grade of Pythagorean pupils.[4][5]
  • 4th century AD – Iamblichus counts it among the qualities of the Pythagoreans.[5]
  • About 1600 – English takes acoustic from French.[3]
  • Modern Greek – It is revived as a learned word under the influence of French.[7]
