In the figure below, the softest sound that a human can hear is the zero point. and has a relatively low response at low frequencies. The process of converting the air pressure from the lungs into audible vibrations is called phonation.When the air passes through the elastic vocal folds and causes them to vibrate, the type of phonation is called voicing. But this is not the case with sounds when they are expressed in decibels. This is because human ear responds as octave bands or 1/3 octave bands respectively for analysis. Vocal sound energy is created when expelled air from our lungs passes through the vocal folds. μPa or 20 x 10, Sound pressure level, which is often abbreviated as SPL or L. In real life, several sources of sounds often occur at the same time.
