we will study the effect of rehabilitation
training based on temporal fine structure on speech in noise perception on
patients over the age of 60 years with mild to moderate hearing loss. Age related hearing loss (Presbycusis) is one
the most common cause of hearing loss worldwide. It is estimated almost 50% of
population more than 75 years old suffer from Presbycusis. Presbycusis mostly
characterized by recognition of target speech in noise environment. Sounds are decomposed by the
auditory filters to slowly varying envelope (E) and rapid temporal fine
structure (TFS). The most important task of TFS is to identify target speech from interfering sounds. Presbycusis highly associated with damage of TFS information. Previous studies indicated
the damage of TFS information is permanent
but in this study we attempt to
prove base on rehabilitation training part of impairment in TFS information
will be reestablished
