The study is designed to examine the effectiveness of a computer-based auditory training program to improve the benefits received by individuals who wear hearing aids. The study will involve 3 groups - a computer-based training group, an active listening group which will involve listening to books on CD, and a placebo group that receives no additional treatment.

---|---|---|---|---|
Primary | Words-in-Noise Test (WIN) Change | Monosyllabic words (NU-6 female version) with a carrier phrase were presented auditory only in a multitalker babble.The participant is asked to repeat the last word of each phrase. The total number of correct words is input into the Spearman-Karber equation to derive a 50% point. This is the signal-to-noise ratio in dB that an individual requires to get 50% of the words correct. This test was completed at baseline and follow up visits. | Baseline, immediate post-intervention (up to 2 to 6 weeks), 6 month follow up | |
Secondary | Abbreviated Profile of Hearing Aid Benefit (APHAB) Change | The Abbreviated Profile of Hearing Aid Performance (APHAP; Cox & Alexander 1995) was used to assess activity limitations and the Hearing Handicap Inventory for the Elderly or Adults (HHI; Ventry & Weinstein 1982; Newman et al. 1990) was used to assess participation restrictions. The APHAP is a 24-item questionnaire that documents hearing difficulties in specified listening situations. The items are answered on a 7-point scale from 'Always' (or 99%) to 'Never' (or 1%) with higher scores indicating greater reported hearing difficulty. The APHAP global score that ranges from 1 to 99 was used for all analyses. | Baseline, immediate post-intervention (up to 2 to 6 weeks), 6 month follow up | |
Secondary | Hearing Handicap Inventory for the Elderly (HHI) Change | The HHI is a 25-item questionnaire that assesses the social and emotional consequences of hearing loss. The HHI for the elderly is for individuals age 65 years and older (Ventry & Weinstein 1982); the HHI for adults is for individuals aged 64 years and younger (Newman et al. 1990). The versions differ in the wording of three questions. The participants were asked to complete the appropriate HHI for aided listening to reflect their residual hearing handicap. HHI items are answered on a scale of Yes (4 points), Sometimes (2 points) and No (0 points), with higher scores indicating greater reported hearing handicap. Total HHI scores, which can range from 0 to 100, were used for all analyses. | Baseline, immediate post-intervention (up to 2 to 6 weeks), 6 month follow up |
