“…In this regard, the psycho-acoustical investigations that aimed at understanding the direct influence of different frequency components on the brain activity (involving cognitive functions) and consciousness have also been carried out (Tufail et al, 2011;Raman et al, 2013;Fukushima et al, 2014;Han-Moi et al, 2014). Such findings help in crafting various desired/influential sound frequencies (that could eISSN 1303-5150 www.neuroquantology.com range over spectrum of frequencies below (infrasonic) and above (ultrasonic) the audible (sonic) range; 20Hz to 20,000Hz) for alternative healing purposes (Rakovic et al, 2004;Bharucha et al, 2006;Dossey, 2008;Huang, 2010;Gaona et al, 2014;Pereira, 2015b).…”

Fractals are built from patterns generated from immense complexity within the resonant frequencies that connect and tune the universe. Play of such frequencies would result in the exchange of energy and coupling of informational systems at various levels and scales. The present essay serves as a small ride into life's association with such phenomenon. At a fundamental level communication happens via process called 'resonance' (in energy terms), and this in turn manifests at a physical (or material) level as self-replicating and self-resonating patterns called 'fractals.' This could be the reason why at a physical level every structure (associated with both animate and inanimate entities) carries this fractal imprint nature, making it the cosmic signature (as embedded in the spatial grain). The fractal patterns popping out in the natural world surrounding us could be thought of as frozen energy or resonant life patterns. Thus, we hypothesize life could have emerged or appeared as a 'fracto-resonant' phenomenon, resulting from the play of interference between material and non-material aspects. In this regard, we propose frequencies or vibrations to be more fundamental to life and call for scientific studies that aim at understanding the effect of various frequencies and vibrations on life forms and consciousness.

There is considerable debate over the benefits of recording and rendering high resolution audio, i.e., systems and formats that are capable of rendering beyond CD quality audio. We undertook a systematic review and meta-analysis to assess the ability of test subjects to perceive a difference between high resolution and standard, 16 bit, 44.1 or 48 kHz audio. All 18 published experiments for which sufficient data could be obtained were included, providing a meta-analysis involving over 400 participants in over 12,500 trials. Results showed a small but statistically significant ability of test subjects to discriminate high resolution content, and this effect increased dramatically when test subjects received extensive training. This result was verified by a sensitivity analysis exploring different choices for the chosen studies and different analysis approaches. Potential biases in studies, effect of test methodology, experimental design, and choice of stimuli were also investigated. The overall conclusion is that the perceived fidelity of an audio recording and playback chain can be affected by operating beyond conventional levels.
