Though he could recover in a few days from symptoms, a tinnitus as well as difficult-hearing of right ear began a year afterward. By examination, it has been proved that his right ear had a marked auditory disability in the area higher than c(2) and complete deaf at c(6). 2) 50 years-old male; experienced 4 electric shocks, i. e., A. C. 3.300V. 3 times; A. C. 60.000V. once. In every time, he felt an obstruction feeling of ear, tinnitus, as well as vertigo after the disaster.
