%X echolocation is an ability that can be used daily by human beings, even without being conscious of it. it turns out to be crucial to the efficient independent mobility of the blind person, an aspect that is severely affected by blindness. it implies using the information that emerges from self-produced sounds and their reflexions in order to locate and recognize unseen objects. according to the new cognitive and ecological paradigms in perception, it is believed that the primary function of the auditory system is to determinate, i.e., to localize and recognize, the characteristics of the sound source through the sounds emitted by it. within this context, it has been very recently argued that echolocation (i.e., the ability to locate and recognize biologically relevant secondary sound sources through the information contained in the direct-reflected couple) is a variant of that general process of primary sound sources determination. two recently established scientific paradigms have specially enriched the study of this amazing ability: the sensorimotor contingency theory and the sensory substitution perspective. the first approach claims that the perceptual and motor systems are coupling processes that demand a thoroughly unified treatment. the second approach considers that, for example, vision loss does not mean loss of the ability to see since it is possible to see with the ears or the skin. the central idea is that the information usually captured by vision may instead be captured by touch or audition, on account of brain plasticity. in this way, in echolocation (which represents a kind of 'seeing with the ears' natural sensory substitution system that is part of the human endowment) action consists of the exploratory activity that the subject carries out through self-generation of sounds and head and/or cane movements while sensation refers to certain tonal or spatial percepts related to the presence and characteristics of the objects that the subject (implicitl
