Review on Spatial Hearing Processing Disorder and Its’ Rehabilitation Methods among Elderly in Iran

The hearing system can detect the location of the sound source and help uspay attention to it. In the presence of the background noise, it helps detectingthe desired signal (especially speech) and comprehend it. This ability is calledspatial hearing processing. Spatial hearing processing disorder can adverselyaffect signal detection in noise, which is very important in the elderly. The aimof the present paper was reviewing the spatial hearing processing disorder andits ‘rehabilitation methods in Iran for the elderly.In this narrative paper, theoretically, all papers on spatial hearing processingdisorder and its’ rehabilitation methods among the elderly in Iran from 2000to February 2021 were collected. The papers with the following keywords inMedline, Google scholar, Proquest, science direct, Scopus, and Magiran werestudied 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.Aging adversely affects the spatial hearing processing and especially in complexenvironments, so rehabilitation of spatial hearing disorders can potentiallyimprove comprehending speech in noise for the elderly. The results of thisstudy showed that there is absolutely necessary to develop different rehabitationprograms for different elderly groups base on their needs.
