Relevance – Vast numbers of blast-injured Operation Iraqi Freedom/Operation Enduring Freedom/Operation New Dawn personnel report postconcussive symptoms (headache, dizziness, poor memory, and difficulty concentrating). – Additionally, many report hearing problems yet have no measurable auditory deficits.

Self-report measure: Functional Hearing Questionnaire. Behavioral measures: – Speech, Spatial, and Qualities Questionnaire. – Hearing in Noise Test. – North American Listening in Spatialized Noise-Sentence Test. – Adaptive Tests of Temporal Resolution. – Modified Digit Span Test. – Time Compressed Speech Test. – Staggered Spondaic Word Test. – Woodcock Johnson Story Recall. – Stroop Color and Word Test.

Participants showed deficits relative to published normative data on a number of performance-based tests that have demonstrated sensitivity to auditory processing deficits. More than the expected number of participants (15.9%) performed ≥1 standard deviations below the mean on several measures (speech understanding in noise, binaural processing, temporal resolution, and speech segregation). However, performance was not universally poor, with approximately 53% of participants performing abnormally on between 3 and 6 of the 10 measures.
