Some incredible sensors that let us monitor important signals from distant sources include sounds (by audition) and smells (by olfaction). There are related systems for detecting position and movement of the body (the vestibular system, related to the auditory system) and tastes of foods (the gustatory sense). Humans rely on speech sounds to provide a basis for our social relations and for the transmission of knowledge between individuals. Species have unique auditory capabilities that helped their ancestors solve important problems of survival. A single alternation of compression and expansion of air is called one cycle: pure tone: a tone with a single frequency of vibration, represented by a sine wave. The force that sound exerts per unit area, usually measured as dynes per square centimeter. In practical terms, amplitude corresponds to the volume of a sound.
