Mélyhangs

Mélyhangs refers to low-frequency sounds. In acoustics and audio engineering, it is generally understood to encompass sound frequencies below approximately 200 Hz. These frequencies are often perceived as deep, resonant, or powerful. The human ear's ability to perceive very low frequencies diminishes with age, and the lowest limit of human hearing is typically considered to be around 20 Hz.

The production of mélyhangs often requires specialized equipment. For example, subwoofers are loudspeakers designed specifically to reproduce very low frequencies. In music, mélyhangs are fundamental to the rhythm section, provided by instruments like bass guitars, double basses, and kick drums. They contribute significantly to the overall feel and impact of a piece of music.

In the natural world, mélyhangs can be generated by phenomena such as thunder, large animal vocalizations, or seismic activity. The perception of mélyhangs can also be influenced by the environment; they tend to travel further and are less susceptible to absorption by soft surfaces than higher frequencies. In sound design and audio mixing, careful control of mélyhangs is crucial for achieving a balanced and impactful sound. Overemphasis can lead to a muddy or boomy sound, while insufficient mélyhangs can result in a thin or weak audio experience.
