Abstract

Sound quality evaluation is one of the psychoacoustic methods to measure subjective judgements for sound color. The purpose of this study is to investigate sound quality benefits of bimodal users by comparing sound quality scores between bimodal hearing condition and unilateral cochlear implant(CI) condition as a preliminary study. Thirteen bimodal users and seven unilateral CI users were participated in this study. Audiologists performed pure tone and speech audiometry and measured functional gain and real-ear insertion gain. Subjective assessment of sound quality was followed with four sounds including violin sound, male and female voices, and refrigerator noise. Participants judged the sound quality with six sound quality index. Bimodal users showed mean 0.8 points more sound quality improvements in bimodal condition than unilateral CI condition. Group comparison between bimodal and unilateral CI users showed no differences. A follow-up study of sound quality tools and methods should be considered to evaluate subjective bimodal benefits of cochlear implant users.

음질평가는 물리적 음향 자극에 대해 주관적으로 지각되는 음색을 평가한다는 측면에서 심리음향학적 측정과 관련이 있다. 본 논문은 인공와우 사용자의 음질평가를 위한 예비연구로서 바이모달 인공와우 사용자를 대상으로 음질평가를 시행하고 인공와우만 착용했을 때와 바이모달을 착용했을 때의 음질평가 차이를 파악하고자 하였다. 총 13명의 바이모달 인공와우 사용자와 7명의 편측 인공와우 사용자가 연구에 참여하였고 순음 및 어음 청력검사, 보청기 기능이득과 실이삽입이득을 측정하였다. 음질평가에서는 바이올린소리, 남자와 여자 노래소리, 냉장고 소음의 4개 음향자극을 방음실에서 들려주고 6개 음질평가 항목에 대해 0에서 10까지의 척도로 표시하도록 하였다. 검사결과 바이모달 사용자는 편측 인공와우만 착용했을 때보다 바이모달을 착용했을 때 음질평가 5개 항목에서 0.8점 높았고, 바이모달 사용자와 편측 인공와우 사용자 그룹간 비교에서는 두 그룹 사이에 차이를 보이지 않았다. 주관적 측면의 바이모달 혜택 측정을 위해서 좀 더 체계적인 음질평가 도구와 방법에 대한 후속 연구가 필요할 것으로 생각된다.
