Abstract: Over the years, it has been widely believed that the blind individuals possess enhanced sound localization abilities that help them to navigate and orient in space in the lack of visual stimuli. In addition to this, it has been argued that the visually impaired people develop increased capacities of the remaining senses (auditory skills, in particular) that exceed those of the normally sighted individuals. The following paper aims to present and compare the most notable sound localization experiments that involved the participation of both blind and sighted control subjects. As the results of these studies provided different results, they have been classified in experiments that show a better localization performance for the blind participants and on the other hand, experiments that yielded equal or worst localization accuracy in the case of the visually impaired subjects. The underlying purpose of our research is to understand the modality and the degree at which the presence or absence of visual stimuli affect the spatial auditory resolution for each of the two target groups.
