Casque audiothumb|Un casque audio des années 1970. Un casque audio est un dispositif qui se place contre les oreilles et sert à restituer des contenus sonores. Le casque audio est composé de deux écouteurs, un pour chaque oreille. Chaque écouteur renferme un transducteur capable de restituer toutes les fréquences audibles, ou du moins la plus grande partie. L'immense majorité des casques utilise un transducteur électrodynamique (en langage courant, une sorte de haut-parleur miniature) mais il existe des casques utilisant d'autres types de transducteur : électrostatique, electret Ce sont toutefois des produits généralement marginaux et souvent très onéreux.
User experience designUser experience design (UX design, UXD, UED, or XD) is the process of defining the experience a user would go through when interacting with a company, its services, and its products.

Caesium standardThe caesium standard is a primary frequency standard in which the photon absorption by transitions between the two hyperfine ground states of caesium-133 atoms is used to control the output frequency. The first caesium clock was built by Louis Essen in 1955 at the National Physical Laboratory in the UK. and promoted worldwide by Gernot M. R. Winkler of the United States Naval Observatory. Caesium atomic clocks are one of the most accurate time and frequency standards, and serve as the primary standard for the definition of the second in the International System of Units (SI) (the modern form of the metric system).
