title: Is the unaided ear effect independent of auditory aging?
abstract: As a group, adults with bilateral symmetric sensorineural hearing loss (SNHL) who receive a monaural hearing aid fitting experience a progressive decline in their word recognition score (WRS) for monosyllabic word materials in the unaided ear but not in the aided ear. However, adults with binaural fittings do not demonstrate a similar deterioration in their WRS. In an effort to determine the role of senescent auditory changes on the unaided ear effect, a retrospective investigation was carried out on a group of hearing aid wearers. Using NU-6 to assess the WRS, this investigation attempted to answer the following question: is the unaided ear effect related to asymmetric senescent auditory changes? The present results indicate that the unaided ear effect is not related to such an asymmetric effect since it is shown to occur in adults with SNHL whether in the fourth or seventh decade of life.
