Abstract
Conclusion. The results indicate that susceptibility to impulse noise differs in the three species. Objective. To test the hypothesis that there is different susceptibility to impulse noise trauma in three species: the guinea pig, rat and mouse. Materials and methods. Three groups of animals were exposed to the same impulse noise and the effect on cochlear pathology was examined using auditory brainstem response thresholds. Results. It was found that the rat and mouse are more sensitive to impulse noise than the guinea pig.
