Sensorineural hearing loss is the most common sensory deficit among older adults. There is no clinically proven method to predict the onset of this condition, as its occurrence is generally slow and progressive, affecting both ears equally. Recent studies have documented that hearing loss in older adults is independently associated with reduced cognitive functioning, mood and social interaction, and that hearing aid use and auditory training could improve cognitive abilities, social, emotional, psychological, and physical well-being of people. Despite the high prevalence of hearing loss in older adults, and the consequences for health outcomes, people are generally slow to acquire hearing aids, and almost two-thirds of older adults with hearing impairment do not use hearing aids. The popularity of auditory training has also declined in recent years and the focus of research has been shifted to only improving wearable amplification such as hearing aids. No research has been designed to specifically look at the effect of both hearing aid use coupled with auditory training on cognitive performance in older adults.
