''ONE SMALL STEP FOR MAN, ONE GIANT LEAP FOR MANKIND''


NEIL ALDEN ARMSTRONG (MOON, 1969)

 

Everybody knows, that hearing (or audition) as a sense of sound perception, is one and the first of five main physiological capacity of organism that provides us data for full human living. Prior to sight, taste, smell and touch, unborn babies are thought to start to hear at around 24 weeks into gestation as neurons begin to form connections in the auditory cortex of the brain. From inside the womb the baby experiences low frequency sounds like the mother's heart beat and a muffled version of her voice. Researchers of Harvard Medical School (in a study led by Amir Lahav) have proved that sounds similar to those experienced by an unborn baby in the womb can boost the growth of the brains of infants even those who born prematurely (ex.: Science Mag; Sound Of Mom’s Voice Boosts Brain Growth In Premature Babies, February 23, 2015, Emily Underwood).
 

Sounds, music and extraneous noises have a direct impact on the human body, development of brain, immune and endocrine systems, the formation of the emotional structure of the personality, and as a result determine the quality of life of a person as a whole. Listening to live music performed by our favorite musicians and vocalists cheers us up and makes us happy provoking the release of endorphins and dopamine. For this reason, the quality of recording and playback systems that allow us to listen to truly "live" music in the recording directly affects our health.
