Compared to other living creatures man has developed extremely flexible vocal chords and this fact together with the variable resonance cavity are the prerequisites for the differentiated ability to articulate which is the basis for human speech.
The tone colour is determined by the resonance and the sort of vibration of the vocal chords. Resonance and also the intensity with which the vocal chords vibrate are decisive for the loudness.

Information and ideas:
The link can be made from the physics and physiology of sound production to speech and communication as prerequisite for the development of human intelligence and social forms of human interaction.
