Specific frequencies of sound induce distinct psychological states
the verdict
CONTESTED
the evidence cuts both ways
confidence 46/100
While multiple studies suggest that specific acoustic frequencies or binaural beats can influence mood, sleep, and cognitive performance, systematic reviews highlight significant methodological heterogeneity and conflicting empirical outcomes across the field.
