Resumen
In humans, multisensory interaction is an important strategy for improving the detection of stimuli and reduce the variability of the response. In some cases, the information collected by a sense can affect other perceptual modalities. It is known that the presence of visual information affects the auditory perception in the horizontal plane (azimuth) but there are few researches that study the influence of this information in the auditory distance perception (ADP). In general, the data obtained from these studies are contradictory and do not completely define the way in which visual cues affect the perception of the apparent distance of a sound source. In the present work, psychoacoustic experiments were performed considering ADP in humans by including and excluding visual cues. The data shows that the apparent distance from the source is affected by the presence of visual information and that subjects can store in their memory a representation of the environment that later improves the perception of distance.
