Abstract
Chinchillas are exposed to impulses of 155, 161, or 166 decibels peak sound pressure level with a duration of 1 millisecond. The 155 decibel level produces no permanent threshold shift, but animals develop outer hair-cell lesions. Levels of 161 decibels produce varying hair-cell loss and permanent threshold shifts. Levels of 161 decibels produce substantial hair-cell loss and permanent threshold shift.
