RESUMO
Human exposition to excessive sound levels has been a cause for preoccupation since the early stages of our civilization. In the Modern Era, sound levels have increased not only at work but also during social and leisure activities, leading the hearing loss induced by high levels of sound pressure to be considered the second most important cause of deafness. Bearing that in mind an experimental work was designed in an attempt to search for the effects of high sound pressure and Ginkgo biloba EGb 761 dry extract to the cochlea of albino adult female guinea pigs with the evaluation of cell architecture alterations by means of light microscopy and also by the evaluation of alterations to the sensory epithelium with the scanning electron microscopy (SEM) array
