Does 432Hz tuning improve your wellbeing? A music psychologist unpacks the evidence

Sound Therapy Scientific Skepticism Psychology of Perception

The article examines the claim that music tuned to 432Hz or the use of binaural beats can provide healing or cosmic alignment. It concludes that while some people find lower frequencies relaxing, there is little scientific evidence to support the idea of specific 'magical' frequencies for wellbeing.
