There is no scientific evidence to suggest that the frequency of 528 Hz is inherently harmful. In fact, the concept of certain frequencies being harmful or beneficial to human health is largely based on pseudoscience and unsubstantiated claims.
The idea that specific sound frequencies can have healing properties or detrimental effects on the body and mind is a part of a pseudoscientific belief system known as sound healing or vibrational medicine. Proponents of these beliefs often assign specific frequencies to various physical, emotional, or spiritual effects, but these claims lack scientific validation.
Sound itself can have a variety of effects on individuals, including relaxation, stress reduction, and mood enhancement. However, the impact of sound is highly subjective and can vary from person to person. Furthermore, the specific frequency of a sound does not inherently determine its positive or negative effects.
It's important to approach such claims with skepticism and rely on scientific research and evidence-based practices when it comes to matters of health and well-being. If you have concerns about specific frequencies or their effects, it is advisable to consult with qualified healthcare professionals or experts in relevant scientific fields.
