A Zwicker tone refers to a phenomenon in psychoacoustics, specifically related to auditory perception and sound analysis. It is a type of phantom auditory sensation that occurs when certain sound frequencies are presented, and listeners perceive a tone that is not actually present among those frequencies. This effect is often associated with the way the human auditory system processes complex sounds, including how it fills in gaps or creates a perception of additional tones based on the harmonics and frequency components of sounds that are played.
