Researchers in Italy found blind people needed additional timing cues to accurately judge the relative location of sounds played from a line of speakers.

“This work teaches us that our audio-space representation is mediated by our visual experience,” says first author Monica Gori of the Istituto Italiano di Tecnologia. “In absence of vision, auditory spatial skills are not always enhanced — and in some cases, such as in the space bisection task studied here, these can be impaired.”
