Abstract

The temporal processing is one of the physiological mechanisms of hearing most affected by aging (Kolodziejczyk, Szelag, 2008; Liporaci, 2009; Fitzgibbons, Gordon-Salant, 2010). Besides the aging process, it is believed that the presence of hearing loss may increase difficulties in temporal processing tasks (resolution and temporal ordering). Objective: To evaluate the effect of hearing loss in temporal auditory processing in the elderly. Methods: 15 individuals will be selected with normal hearing and 15 individuals with hearing loss to moderate, aged 60 to 75 years. As inclusion criteria, all respond to an interview, hold the Mini-Mental State Examination and basic audiological evaluation. The evaluation of temporal processing is accomplished through the Gap in Noise Test - GIN and Duration Pattern Test-TPD. The statistical study of this project will include the external advice of a qualified professional. Expected Results: In the present study, it is expected to expand the knowledge of the effects of aging on temporal processing, as well as to investigate the influence of hearing loss on solving skills and temporal ordering in the elderly.
