Picture 1.A sound wave<br />
Important: Sound is constituted of many waves of different characteristics,<br />
making up a wave cloud. This multiplicity of variable waves causes different<br />
effects.<br />
Volume can be translated as hearing level.<br />
Pitch is the subjective magnitude and refers to the high or low quality of a<br />
sound.<br />
Timbre (tone) is what allows for the distinction between sounds.<br />
Sound vibrations, either musical or not, reach our body and, with some<br />
attention, we can feel those vibrations. As it strikes the tympanum, a low sound<br />
makes an impact that is not, however, local” skin and tissues also react to<br />
sound vibrations. This resonance can be more or less important depending on<br />
the other characteristics of sound: its volume, pitch and timbre 1 .<br />
4.2. Hypothesis 2: compensation<br />
The human being, as well as most animals, cannot survive without the eye-ear<br />
set. The ear is by far the most important, as defends Emile Leipp (2010).<br />
Hearingcovers the whole area where the subject stands. Leipp states that the<br />
ears first perceive danger and only afterwards does sight capture and evaluate<br />
