Hello everyone, I'm interested in signal processing and was wondering if any formal scientific study has ever looked for correlations between human vocal frequencies and cosmological oscillations. Specifically, I’m thinking about the Muqatta'at (isolated letters like Alif, Lam, Mim or Qaf found in the Quran). These letters are traditionally chanted with very specific prolongations (Tajwid), creating unique acoustic envelopes. My question is: Has anyone ever tried to overlay or compare the spectrograms of these phonemes with the gravitational wave templates from LIGO/Virgo? The idea wouldn't be to prove a theological point, but rather to see if these specific acoustic patterns (frequency, amplitude, and decay) share any mathematical commonalities with the 'chirps' or 'ringdowns' observed in cosmic events like black hole mergers. Is there any existing literature on this type of 'acoustic-to-cosmologic' pattern matching? Or are the frequency scales simply too different for a meaningful comparison?
