At the phylogenetic level, hearing was the first sensory system to develop in evolution and ontogenetically (“Development of Auditory and Vestibular Systems - 1st Edition,” n.d.). to develop in the womb.
The human auditory system continuously analyzes acoustic signals, which are filtered and interpreted by cortical and sub-cortical brain structures that cause acute responses in the autonomic nervous and the endocrine system, even during sleep (“Cardiovascular Effects of Noise on Man – Wolfgang Babisch,” 2015).
The effects of low frequency sounds and vibrations can affect hemodynamic, neurology and musculoskeletal systems by impacting endothelial cell stimulation, kinase protein stimulation and nerve stimulation, respectively (Bartel and Mosabbir, 2021). Some studies have shown improvements in patients with fibromyalgia (Naghdi et al., 2015). It also has impacts on visual functions, concentration, and continuous and selective attention (Pawlaczyk-Luszczyńiska et al., 2005).
