Akustischer

Akustischer is a German adjective meaning "acoustic" or "relating to acoustics." It describes sound-related properties, phenomena, or equipment and is used in science, engineering, musicology, linguistics, and architecture. The base noun Akustik (acoustics) comes from Greek akoustikos "able to hear," from akouō "to hear." As an attributive adjective, akustischer declines to agree with the noun: masculine nominative akustischer Klang, feminine akustische Stimme, neuter akustisches Signal, plural akustische Eigenschaften.

Common uses include akustischer Klang (an acoustic sound), akustische Eigenschaften (acoustic properties), and akustisches Signal (an acoustic signal). The term appears in fields such as Raumakustik (room acoustics), Lautsprechertechnik (loudspeaker technology), and Audiotechnik. In musical and linguistic contexts, it can describe the perceptual or physical attributes of sound, such as timbre, resonance, or phonetic realization.

In broader usage, akustischer coexists with the cognate Akustik and related terms in other languages; it is contrasted with "optisch" (optical) or "elektrisch" (electrical) when describing systems that involve multiple physical domains. See also Akustik, room acoustics, and sound reproduction.
