Although the neurophysiological responses of the human brain to auditory stimuli have been substantiated through modern imaging techniques, the process of digitalization has created a new domain in which scientific data are manipulated through claims of miraculous effects. This study aims to examine the scientific foundations, technical accuracy, and effects on individual perception of healing frequencies presented on social media and digital music platforms under titles such as 528 Hz and 432 Hz, from the perspective of music psychology. Within the scope of the research, 150 pieces of content selected through purposive sampling from seven different digital platforms were evaluated using FFT (Fast Fourier Transform) spectrum analysis and qualitative content analysis techniques. The findings of the technical analysis reveal that a remarkably high proportion of the examined content, 92%, did not contain the specific frequency values promised in their titles, while 86% of this content consisted solely of low-tempo and simple melodic structures. The most striking finding of the study is that, despite technically incorrect frequencies, users’ comments exhibited a strong prevalence of reported healing and relaxation. This suggests that the perceived positive effects may be interpreted as a powerful placebo effect triggered not by the physical frequency value of the sound itself, but rather by the mystical meaning attributed to the content. It may also be explained by the natural relaxing effect of low-tempo music on the parasympathetic nervous system. In conclusion, healing frequencies on digital platforms appear to function less as a technical reality and more as digital rituals to which modern individuals resort in their search for coping mechanisms against stress. By placing the gap between the objective physical properties of sound and its subjective perception within a rational framework through data from music psychology and psychoacoustics, the study documents the extent of disinformation in the literature
