The Psychoacoustics of Siren Songs
In Homer's Odyssey, the Sirens' chant is described as irresistible and soothing. Acoustic science shows that multi-harmonic sine wave superposition coupled with a 4–7 Hz theta binaural beat induces deep psychoacoustic entrainment. When two slightly detuned frequencies (e.g., 220 Hz and 224 Hz) play in separate ears, the auditory cortex perceives a soft 4 Hz beat that promotes relaxation while harmonic overtone shimmer keeps the brain spellbound.
