[Morphological evaluation of the organ of Corti in the guinea pig subjected to acoustic trauma. I. Surface preparation study].
Adult guinea pigs (250-500 g) were exposed to a chronic wide-band noise, at intensities ranging from 117 and 133 dB(A) at different times. The objective of this first part of the study is, after the lesions are established, to classify and put into order the structural damage produced by noise, using surface preparations observed with the light microscope and specimens prepared for scanning electron microscopy, from the organ of Corti.
