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). The presence of hearing loss can increase the difficulties of the elderly in solving tasks and sequencing. Just as the beginning of the aging process, there is still no consensus in the national and international literature about the beginning of the deterioration of temporal processing and what the determining factor of this performance deterioration generated by aging or injury of the peripheral auditory system. Objective: To evaluate the effects of aging and hearing loss in temporal auditory processing. Method: Will be selected 45 individuals with normal hearing and 45 subjects with hearing loss to moderate, aged 30-75 years. Participants will be placed in groups according to their age and the presence or absence of hearing loss. As inclusion criteria, all of them respond to an anamnesis and mini mental state exam and basic audiological evaluation. The assessment of temporal processing is performed by means of the Gap in Noise and Test Pattern and Duration. The statistical study of this project include external advice from a professional. Expected Results: The present study is expected to broaden the knowledge of the effects of aging on temporal processing as well as investigating the influence of hearing loss in the process of declining solving skills and sequencing.
