Abstract :
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.
Methods: 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 rehabitation programs for different elderly groups base on their needs.
