A Critical Evaluation of Acoustic Frequencies on Human Physiology and Neuroplasticity: Differentiating Empirical Science from Popular Pseudo-Scientific Claims

This paper critically evaluates alternative therapeutic claims suggesting that specific acoustic frequencies (e.g., 432 Hz, 528 Hz Solfeggio scales, and binaural beats) can induce cellular healing, structural DNA alteration, and profound physiological transformations through the lens of biophysics, molecular biology, and neuroscience. While empirical evidence refutes the possibility of mechanical sound waves altering covalent bonds within the DNA macromolecule or functioning as miraculous healing agents, neuroscientific data confirms that specific auditory stimulations—specifically through brainwave entrainment—can modulate neural oscillations, alleviate anxiety, and enhance cognitive relaxation.
