Introduction
Elderly health has increasingly aroused the interest of researchers, as the population in both developed and devel-oping countries is aging.It is estimated that by 2040 developing countries will have a billion people aged 60 years or older.Given the rapidity and magnitude of this increase,care for this specific group is essential, so they can age ingood health and with good quality of life.The most common types of hearing loss are presbycusis (due to aging) and noise-induced hearing loss (NIHL).4NIHLis due to continued exposure to loud noise levels, resultingin gradual loss of auditory acuity and is usually bilateral,symmetric, sensorineural and irreversible. It usually affectsthe high audiometric frequencies of 3000---6000 Hz.The etiology of hearing loss also has genetic components, in addition to environmental ones, and more recently, innerear inflammatory response induction and up-regulation ofproinflammatory cytokines were evaluated in the presenceof exacerbated noise. Several researchers have reportedthe presence of inflammatory cells in the steady state andtheir increase after lesions in the inner ea
