This study was aimed to understand the effects of earphone sealed and volume on while do Sound Subject Accomplishment. we make a some hypothesis. Because unearth, this variable are connect occur hard of hearing. setting up six subjects were asked to sound subject accomplishment on the Three quality (normal, middle and high), two sealed quality (low sealed(Don`t use earphone cotton), sealed(use earphone cotton)).
During each trial, before to test, researchers hear same volume quality sound to they be hear test sound, and
they solve a question(korean, English) and 10minutes rest. and Repeat this experiment six time. But each test they
solve different type question, because avoid to method of learning. At result, all hypothesis have proven. norma
l level volume percentage of correct answers are more higher than middle level volume, and middle level volume
percentage of correct answers are more higher than high level volume. And, low sealed percentage of correct
answers are more higher then sealed.
when test time some testers appeal earache and little hearing problem. It is prove noise-induced temporary
threshold shift, maybe repeat this problem, we consider noise-induced permanent threshold shift.
