hangkeltés

Hangkeltés is the process by which audible sound is produced by a source and transmitted through a medium. In Hungarian usage the term covers physical, biological, and technological aspects of sound generation, ranging from natural vocalization to engineered sound sources.

Sound is created when a source experiences periodic or transient vibration, generating pressure fluctuations in air or another medium. The frequency of the vibration determines pitch, the amplitude determines loudness, and the timbre arises from the spectral content and the manner in which the source is excited. The surrounding medium and its characteristics influence how the sound propagates and is perceived.

Sources of hangkeltés can be biological, such as the human voice or animal calls; mechanical, including musical instruments, bells, engines, and other moving bodies; or electronic, such as loudspeakers, transducers, and synthesis equipment. The design of the source, its excitation method, and the acoustic environment shape the resulting sound.

Hangkeltés is studied in acoustics and phonetics to understand how sounds are produced and how listeners perceive them. It is central to music technology and instrument design, voice training, and audio engineering, including the development of synthesis methods and effects. In engineering contexts, hangkeltés also covers noise generation and control, as well as the efficiency and transparency of sound sources.

Etymologically, hangkeltés combines hang, meaning sound, with keltés, meaning generation or creation. Related concepts include phonation, acoustics, and sound synthesis.
