Histological Evaluation of Inner Ears.
Abstract
The purpose of this contract was to support the USAARL research program on the auditory effects of blast overpressure (BOP). The statement of work for this contract identified two broad areas of responsibility; (a) to perform all the required histological work relating to the BOP projects at the USAARL and at the Albuquerque, New Mexico (EG&G) test site; (b) to assist in the on-site (USAARL) physiological and behavioral testing of experimental animals. In mid-1995, the decision was made to terminate this program (ref. Blast Program Review, Aug. 1995) and effective 30 September 1995 our on-site effort ceased, and all on-going animal experiments were terminated. The following was accomplished: (1) Atypical speaker generated impulses were shown to be suitable for modeling the effects of - blast waves. (2) Correlations between audiometry and cochlear pathology were shown to be poor and that individual susceptibility to BOP trauma is highly variable. However, cochlear emissions are a sensitive, frequency specific index of BOP auditory trauma in an individual. (3) One-third octave bands of noise are suitable stimuli for audiometric testing.
