Objectives: Moderate hearing impairment in older age can affect physical and psychosocial health of people. The rate of isolation, lack of self confidence, depression and probably dementia in this people is high. This study was conducted to study the hearing aid effect on older adults depression in tehran nursing homes.

Methods & Materials: In this study depression was assessed in 3 groups of older adults: 30 normal hearing older adults, 30 hearing impaired older adults without hearing aid and 20 hearing impaired older adults with hearing aid. Beck depression inventory (ii) was used to assess depression. For analyzing data one way anova was used.

Results: Mean scores in bdi was 11.43, 21.53, 16.40 for groups. The difference between groups was significant. Correlation between age and depression was significant in 1 and 3 groups.

Conclusion: It seems that hearing aid use is effective in decreasing depression in older adults.

Objectives: Hearing loss is a major public health problem and has higher prevalence in elderly persons. Present study was conducted with the aim of characterizing age-related changes on audiometric thresholds and word discrimination ability of people with age range of 30 to 100 years.

Methods & Materials: Hundred ninty persons (male 53.68% and female 46.32%) in seven aged decades were studied from May 2005 to Oct 2007 in Tehran. Individuals who referred for auditory evaluation had concern regarding presence of a kind of hearing problem. Pure tone audiometry, word discrimination score and immittance audiometry were performed for those people who has no previous history of auditory impairment and/or experiencing hearing hazardous agents.

Results: There was a significant reverse correlation between recording of acoustic reflexes with both age and hearing loss average. Loss of hearing sensitivity among seven aged decades was significant statistically. Hearing loss showed more decrement in men than women in all audiometric frequencies, and the difference between them was significant in higher frequencies. Decrease of word discrimination score with age growth was significant, and with 12.63% permanent tinnitus, 6.84% vertigo/dizziness and 4.21% history of hearing aid usage were reported in all individuals.

Conclusion: Hearing sensitivity declines gradually and progressively with aging. Effects of hearing loss and some of it's associated disorders specially tinnitus and vertigo/ dizziness on degree of communication and quality of life in such individuals and higher prevalence in aged people reveals the necessity of scientific and executive programming for identification and treatment of auditory problems in such population.
