Acoustic Basis Of The Use Of Singing

The intensity of breath, the size and thickness of the vocal cord, the size of the adjustable sympathetic chord cavity, the degree of muscle tightness, relies on the adjustment and control of high nervous center to cerebral cortex random moving function, sense of hearing and inherent feeling. If we think of human body as a musical instrument when we make sounds, then there hasn't been an objective standard to exam this special "instrument".Voice acoustics is the frontier branch of science which combines physiology with physics. It's also a new-developing comprehensive discipline. Through the analysis of vocal cord structure and sound production mechanism; and though the elaboration to acoustics theory (e.g. vibration frequency, sound reflection, etc.), voice acoustics provides us scientific theory support to the principle of voice sound production at our daily singing and teaching practices. Thus we can better use and protect our vocal organ, lengthen our artistic life.
