Abstract

In this paper, a subjective assessment for sound quality evaluation of earphones is introduced. Although instantaneous switching among assessed stimuli is very important in the subjective assessment from the simultaneous comparison's point of view, it is physically impossible in the subjective assessment of earphone. Thus, this paper proposes an indirect assessment method using recorded stimuli and accompanied pre-processing and the assessment results are presented.

본 논문에서는 이어폰의 주관 평가 기법에 대해서 소개한다. 음질의 주관 평가는 동시비교를 위한 평가 자극간의 즉각적인 스위칭을 제공하도록 설계되어야 한다. 그럼에도 불구하고 이어폰의 음질 평가의 경우에 있어서는, 물리적으로 평가 자극간의 즉각적인 스위칭이 불가능하여 직접적인 주관 평가에 어려운 점이 있다. 이에, 본 논문에서는 각 이어폰으로부터의 자극을 녹음하여 녹음된 자극간의 동시 비교를 통하여 이어폰을 평가하는 방법을 제안하고, 이에 필요한 선처리들과 평가 결과에 대하여 소개한다.
