SummaryGroups of pigmented guinea pigs were exposed unilaterally to a 15 kHz pure tone at 133 dB SPL for 7.5 min. The inner ears of one group were examined by light microscopy to count damaged hair cells 3 weeks after exposure. Four other groups were investigated using scanning electron microscopy to assess the progression of initial surface changes after sound exposure. Hair cells were examined at 0, 10 and 30 min and compared with those seen at 3 weeks. Drastic stereociliary disturbances were… Expand
Effect of mastoid drilling on hearing of the contralateral ear.
Drilling during mastoid surgery poses a threat to hearing in the contralateral ear due to noise and vibration conducted transcranially. Expand
Does exposure to noise from human activities compromise sensory information from cephalopod statocysts
Lesions in the statocysts of four cephalopod species of the Mediterranean Sea, when exposed to low frequency sounds are revealed, consistent with a massive acoustic trauma observed in other species exposed to much higher intensities of sound. Expand
Pathophysiological Effects of Vibration with Inner Ear as a Model Organ
The results indicate that VWF and numbness have possibly different pathophysiological mechanism and the animal model provides a new understanding of mechanisms leading to vibration-induced cochlear changes and cellular damage. Expand


A quantitative study of the sequence of topographical changes in the organ of Corti following acoustic trauma.
The organs of Corti of 30 guinea pigs were examined quantitatively by scanning electron microscopy either immediately or 1, 3, 7 or 14 days after exposure to 3 kHz at 125 dB SPL for 30 min. LesionsExpand
Primary structural changes in the organ of Corti after acoustic overstimulation.
Thxe appears to be a critical intensity for these initial struciural changes, which only partly can be explained on the basis of a purely mechanical effect. Expand
Changing Relationships between Structure and Function in the Cochlea during Recovery from Intense Sound Exposure
All morphological lesions occurred within regions corresponding tonotopically to the N1 threshold losses, but only the larger lesions, which were observed seven or more days after exposure, fully reflected the extent of the loss of N1 thresholds. Expand
Comparison of various short noise exposures in albino and pigmented guinea pigs

The main differences between the two strains were that in albino guinea pigs fewer ears were damaged after the shortest single exposures and generally more damage occurred after repeated exposures, but no differences were detected in either strain when the interval between repeated exposures was changed.

Hair cell damage in the guinea pig due to different kinds of noise.
The results indicate that the total energy concept is a too simplified hypothesis concerning inner ear damage and the damage to the inner ear was analysed histologically and the loss of outer hair cells was used as damage parameter. Expand
The Effects of Short Noise Exposures in the Guinea Pig *
Guinea pigs have been exposed to 20 kHz at 120 dB SPL for exposure durations of 7.5, 6.5, 5.0, and 3.25-min and killed either 3 or 12 weeks post-exposure. One series of guinea pigs exposed for 30-minExpand
Acoustic trauma in the guinea pig cochlea: Early changes in ultrastructure and neural threshold
Scanning microscopy was used to examine guinea pig cochleas for structural damage immediately after exposure to a pure tone ranging from 96 to 129 dB SPL, finding that N1 threshold losses spread progressively to lower frequencies as exposure intensity increased. Expand
Qualitative and quantitative changes in the guinea pig organ of Corti after pure tone acoustic overstimulation
No significant difference was observed between groups of animals exposed to a sound energy of 9.4 and 37.5 Pa2.h, irrespective of sound intensity, and groups exposed to different intensities did not differ significantly within this energy level. Expand
Variability of noise-induced damage in the guinea pig cochlea: Electrophysiological and morphological correlates after strictly controlled exposures
Functional impairment after 21 days showed large inter-animal variation which was not the result of changes in the effective damaging energy, and unknown factors within the cochlea must be responsible for variations in individual susceptibility to permanent noise-induced hearing loss. Expand
Vulnerability of tip links between stereocilia to acoustic trauma in the guinea pig
The cochleae of anaesthetized guinea pigs were prepared for scanning electron microscopy, immediately after exposure to an intense tone, and the results suggest that tip links between stereocilia are preserved as long as the other links between the stereOCilia and the cytoskeleton of the stereocilium remain intact.
