Abstract

This study aimed to compare acoustic measurements by the high, middle, and low laryngeal heights of male musical theater students. Furthermore, the correlation between the relative height of the larynx and the acoustic measurements was examined, along with the predictability of the relative height (vertical position) of the larynx from acoustic measurements. The participants included five male students majoring in musical theater singing, and acoustic analysis was performed by having them produce the /a/ vowel 10 times each at the laryngeal positions of high, middle, and low. The relative vertical positions of the laryngeal prominence in each position were measured based on the resting position. Results indicated that the relative position of the larynx varied significantly according to laryngeal height, such that as the larynx descended, the first three formant frequencies decreased while the spectral energy at the same frequencies increased. Formant frequencies showed a weak to moderate positive correlation with the relative height of the larynx, while the spectral energy showed a moderate negative correlation. The relative height of the larynx was predicted by eight acoustic measures (adjusted R2 = .829). In conclusion, the predictability of the relative height of the larynx was partially confirmed in a non-invasive manner.

본 연구에서는 남성 뮤지컬 전공 학생의 발성 시 고, 중, 저의 후두 높이 조건에 따른 음향학적 측정치를 비교하고자 하였다. 또한 휴식 시 후두 융기의 높이를 기준으로 후두의 상대적 높이와 음향학적 측정치 간의 상관관계를 알아보고, 후두의 상대적 높이에 대한 예측 가능성을 확인하고자 하였다. 연구대상은 남성 뮤지컬 가창 전공 남학생 5명이었으며, 고, 중, 저의 후두 위치에서 발성한 /아/ 모음을 각각 10회씩 발성하도록 하여 음향학적 분석을 시행하였다. 발성 시, 휴식 시를 기준으로 고, 중, 저 위치에서의 후두 융기의 상대적 수직 위치를 측정하였다. 연구 결과, 후두의 상대적 위치는 휴식 시를 기준으로 유의한 차이가 있었다. 후두가 하강함에 따라 포먼트 주파수는 감소한 반면, 해당 주파수에서의 스펙트럼 에너지는 증가하였다. 포먼트 주파수는 후두의 상대적 높이와 약함-중간 수준의 정적 상관관계를, 스펙트럼 에너지는 중간 수준의 부적 상관관계를 보였다. 후두의 상대적 높이는 8개의 음향학적 측정치에 의해 예측되었다(수정된 R2=.829). 이를 통하여 비침습적인 방법으로 후두의 상대적 높이를 예측할 수 있는 가능성을 일부 확인하였다.
