Akusztikus

Akusztikus is a Hungarian adjective meaning related to sound or acoustics. It derives from Greek akoustikos through Latin acusticus and is used to describe phenomena, instruments, and disciplines dealing with sound. In scientific contexts the term occurs alongside akusztika (acoustics), the branch of physics that studies the generation, propagation, and perception of mechanical waves in gases, liquids, and solids.

Akusztika investigates properties such as frequency, wavelength, speed of sound, and amplitude, as well as phenomena like reflection, refraction, diffraction, absorption, and dispersion. Psychoacoustics, a subfield, concerns how humans perceive sound, loudness, pitch, and timbre. Measurements in acoustics often involve decibels and frequency spectra, and the field spans applications from room design to audio engineering and hearing research.

In music and everyday culture, akusztikus commonly refers to non-amplified performances or instruments, i.e., acoustic guitars, pianos, and string ensembles. An akusztikus koncert or akusztikus verzió denotes unplugged or stripped-down arrangements that emphasize natural timbres and intimate atmospheres. The term is widely used in concert programming, music journalism, and artist branding to signal a focus on traditional or unelectrified sound.

Beyond performance contexts, akusztikus design and management appear in audio equipment, architecture, and education, where the aim is to optimize how sound is produced, transmitted, and heard. The word thus encompasses both scientific discipline and cultural practice related to sound.
