What are the two fundamental types of resonance that occur in the human body? Forced and Free.
Why are the chest and head not good resonators for the projection of sound? Skin, muscle, fat and other tissues damp free vibration and prevent sound propagation beyond the body.
What are the four traits common to all musical instruments, including the voice? A power source, a vibrator, a resonator, and a means of articulation.
Why is the vocal tract considered to be a quarter-wave resonator?
It is a closed/open tube. Frequencies with a quarter-wavelength equal
to the length of the vocal tract are the first to be resonated.
What is the relationship between the harmonic series and the resonance series of a quarter-wave system? resonance series contains only the odd-numbered harmonics.
Define musical resonance. The intensification and enriching of a musical tone by supplementary vibration.
What anatomical structures function as free resonators in the human voice?
The trachea, larynx, and vocal tract which includes: the
laryngopharynx, the oropharynx, the oral cavity, the nasopharynx, and
the nasal cavities. (The last two only function as free resonators when
the soft palate is lowered.)
