Neuroacoustic and Phonetic Profiling of Viṣṇuyoniṁ Kalpayatu Mantra (Hymn): Implications for Feto-Maternal Well-Being
摘要
Traditional mantras (Hymns) are increasingly being studied for their psychophysiological benefits, yet few have undergone detailed acoustic and neurophysiological profiling using modern signal processing methods. The Viṣṇuyoniṁ Kalpayatu mantra, rooted in ancient Hindu scripture, is traditionally indicated for feto-maternal well-being and supports healthy progeny. To explore the acoustic and phonetic properties of the Viṣṇuyoniṁ Kalpayatu mantra and evaluate its neuroacoustic impact on feto-maternal well-being. The mantra was compared with white noise and a non-Vedic recitation format using spectral frequency analysis and comparative profiling. Parameters such as frequency, amplitude, formant structure, and resonance were measured. The mantra demonstrated structured harmonic profiles, optimal frequency ranges (43–430 Hz), and consistent amplitude transitions when recited using the Vedic recitation method. These acoustic features correlated with parasympathetic activation, emotional regulation, and limbic coherence. The Viṣṇuyoniṁ Kalpayatu mantra, when chanted using traditional phonetic methods, offers promising neuroacoustic properties suggestive of potential therapeutic relevance, supporting its integration into prenatal therapy and evidence-based Garbhasanskāra (fetal education) practices.
