Primary outcomePrimary: Hearing Handicap Inventory for Adults (HHIA) — 26.20; 37.34; 19.21 Scale score — p=.05
Summary
The purpose of this study is to study blast-exposed Veterans who report hearing handicap but show normal or near normal results on standard audiometric testing. The characteristics and nature of their auditory and auditory-related skills will be examined, along with whether coexisting PTSD contributes to the hearing problems of these Veterans. In a preliminary treatment study, a sub-sample of these Veterans will be fitted with mild-gain hearing aids to determine if they benefit from low-level amplification of high-frequency sounds.
