hangfeszültség

Hangfeszültség, which translates to "sound stress" or "acoustic stress" in English, refers to the perceived intensity or pressure of a sound. It is a subjective quality that describes how loud or quiet a sound feels to a listener. While often used interchangeably with loudness, hangfeszültség is distinct from the objective physical measurement of sound pressure level. Sound pressure level is a measurable physical quantity, typically expressed in decibels (dB), which quantifies the amplitude of sound waves. Hangfeszültség, on the other hand, is a psychological response influenced by various factors beyond just the physical intensity of the sound.

These influencing factors include the frequency of the sound, the duration of the sound, the listener's hearing acuity, and even the listener's emotional state or context. For example, a sound at a moderate decibel level might be perceived as highly stressful in a quiet, sensitive environment, while the same sound might be barely noticeable in a noisy setting. Conversely, sounds within a person's particularly sensitive frequency range might be perceived as louder or more stressful than sounds at objectively higher decibel levels but outside that range. Therefore, hangfeszültség is a complex interplay between the physical properties of sound and the human auditory system's interpretation and reaction to it. Understanding hangfeszültség is important in fields like acoustics, audio engineering, and occupational health, where the impact of noise on individuals is a concern.
