Long term changes to auditory sensitivity following blast trauma in mice.

ABSTRACT: Blast trauma is a common acoustic/physical insult occurring in modern warfare. Twenty percent of active duty military come into close proximity to explosions and experience mild to severe sensory deficits. The prevalence of such injuries is high but correlating auditory sensitivity changes with the initial insult is difficult because injury and evaluations are often separated by long time periods. Here, auditory sensitivity was measured before and after a traumatic blast in adult CBA/CaJ mice using auditory brainstem responses, distortion production otoacoustic emissions, and behavioral detection of pure tones. These measurements included baseline auditory sensitivity prior to injury in all mice, and again at 3, 30, and 90 days after the blast in the two physiological groups, and daily for
