Abstract

The goal of the present paper is to objectify the intrinsic subjectivity of sound as a media of music by applying psycho-acoustical methodology to the analysis of a musical work. First, 18 sound samples are extracted from "Symponie Fantastique" written by Hector Berlioz, which is a piece of program music, and then the objective Zwicher's sound quality parameters such as: Loudness, Sharpness, Roughness and Fluctuation Strength are evaluated for each of these sound samples. For subjective sound quality evaluation, 9 representative sound quality adjectives are extracted on a basis of program feature of Symponie Fantastique and the first jury test is carried out by using the numeric rating method and the paired comparison method. Three sound quality adjectives, "bright", "noisy", and "realistic" are extracted from the factor analysis of the first jury test result. On a basis of the computed sound metrics and the second jury test result for the three sound quality adjectives, three sound quality indexes are developed to represent the sound qualities of "Symponie Fantastique".

본 논문에서는 심리음향학적 연구 방법론을 음악의 작품 분석에 적용하여 음악의 매개체인 소리에 내재된 주관성을 객관화하고자 한다. 먼저, 대표적인 표제음악인 베를리오즈의 '환상교향곡'에서 18개의 샘플음원을 추출한 다음 쯔비커의 음질 파라메터(Loudness, Sharpness, Roughness, Fluctuation Strength)를 이용해서 샘플음원의 객관적 음질을 평가하였다. 주관적 음질 평가를 위하여 환상교향곡의 표제성을 기초로 9개의 대표 음질형용사를 추출한 다음 수치등급평가법과 쌍대비교법을 사용하여 1차 청음평가를 수행하였다. 1차 청음평가결과의 요인분석법을 통하여 "밝은", "시끄러운", "현실적인"의 세 가지 음질을 추출하였다. 세 가지 음질 형용사를 사용하여 2차 청음평가를 수행하고 그 결과를 객관적 음질 파라메터와 상관분석을 수행하여 음질지표를 개발하였다.
