Background: The hearing system can detect the location of the sound source and help us pay attention to it. In the presence of the background noise, it helps detecting the desired signal (especially speech) and comprehend it. This ability is called spatial hearing processing. Spatial hearing processing disorder can adversely affect signal detection in noise, which is very important in the elderly. The aim of the present paper was reviewing the spatial hearing processing disorder and its ‘rehabilitation methods in Iran for the elderly. Method: In this narrative paper, theoretically, all papers on spatial hearing processing disorder and its’ rehabilitation methods among the elderly in Iran from 2000 to February 2021 were collected. The papers with the following keywords in Medline, Google scholar, Proquest, science direct, Scopus, and Magiran were studied after discarding duplicated papers: spatial stream, binaural advantage, spatial release of masking, spatial hearing segregation, rehabilitation, aging, elderly, speech in noise, localization, training, and Iran . Results: Aging adversely affects the spatial hearing processing and especially in complex environments, so rehabilitation of spatial hearing disorders can potentially improve comprehending speech in noise for the elderly. Conclusion: The results of this study showed that there is absolutely necessary to develop different rehabilitation programs for different elderly groups base on their needs.
