On the basis of experimental data obtained from 420 noise-exposed animals (chinchilla), the amount of sensory cell loss has been quantitatively related to the amount of permanent threshold shift at eight audiometric test frequencies between 0.125 and 16 kHz. The noise exposures, which varied extensively in spectrum, intensity and duration, produced(More)
Changes in the surface morphology of the organ of Corti in the chinchilla were studied following exposure to blast waves at 160 dB peak SPL. The generation and development of a mechanically induced lesion on the organ of Corti was followed over a period of 30 days using scanning electron microscopy. The most prominent feature of the lesion was the complete(More)
This paper reviews the results of several studies on the effects of blast wave exposure on the auditory system of the chinchilla, the pig, and the sheep. The chinchillas were exposed at peak sound pressure levels of approximately 160 dB under well-controlled laboratory conditions. A modified shock tube was used to generate the blast waves. The pigs and(More)
When the organ of Corti is severely traumatized by intense (160 dB) blast waves, such that as much as 7 mm of Corti's organ is torn loose from the basilar membrane, the cells of the inner sulcus respond to the altered biochemical milieu of the endolymph by a profile elaboration of surface membrane, zeiosis and the development of numerous pseudopodia and(More)

T HE time has come for freshman athletes to throw their study machine into high gear and keep it going at top speed until the exams which are so near at hand. • * • They should have kept on the lino all during the term. Those who have done so must redouble their efforts and those who have not must get to it and work overtime on the books which seem to be so(More)
