난청시뮬레이터의 개발에 관한 비교 연구

A hearing loss simulator was developed to simulate hearing impairment for normal hearing listeners. It is focusing on sensori-neural hearing impaired listener"s characteristic. Hearing impaired listener has reduced dynamic range and high threshold and reduced frequency selectivity. There are two existing simulators. So we make a comparative study of our proposed simulator with existing simulators. To confmn the evaluation of performance, we made the experiment with three simulator program.
