Blast Trauma: The Effects on Hearing.
Abstract
This project will determine what effects impulse noise (blast trauma) has on hearing performance, the response patterns of auditory nerve fibers and the morphology of cochlea. Initially, audiograms and psychophysical tuning curves of the normal chinchilla will be measured; then the animals will be exposed to impulse noise. Afterwards, the psychophysical measures will be repeated in order to evaluate the changes in hearing performance. Microelectrode techniques will be used to sample the thresholds and tuning curves of single VIII nerve fibers and the neural results will then be compared with the behavioral data. Finally, the cochleas of the noise exposed animals will be embedded in plastic ans dissected out for light and electron microscopic analysis; cochleograms will be prepared and damage to cilia
