Short-term hearing aid benefit in a large group.

Short-term benefit in a very large group (N = 4,584) following hearing aid treatment was estimated using a revised version of the Self-Assessment of Communication (SAC-Hx). A total of 4,584 veterans with adult-onset hearing loss and mean audiometric findings consistent with a mild to severe, sloping, symmetrical, sensorineural hearing impairment were fitted with hearing aids. Responses to the SAC-Hx were gathered prior to and then 6 weeks following hearing aid fitting.

Norms for the international outcome inventory for hearing aids.

The International Outcome Inventory for Hearing Aids (IOI-HA) is a seven-item survey that was developed for use in research settings to facilitate comparison of data across diverse investigations. The inventory also has potential applications in clinical evaluation of hearing aid fitting outcomes. This article reports the development of norms for the inventory that are suitable for use with group data in research applications, and individual data in a clinical setting.
