Abstract

The purpose of this study was to investigate VHI, V-RQOL, and vocal characteristics of a teacher and singer. 56 subjects were participated in this study (20 subjects are a teacher with vocal nodule, 20 subjects are a singer with vocal nodule, and 16 subjects are normal speakers). All subjects completed the VHI, V-RQOL, and vocal characteristics were measured using CSL 4500(Kay Pentax. USA). 21 subjects completed the VHI, V-RQOL, and vocal evaluation using CSL 4500 twice to assess test-retest reliability. A statistical analysis was performed using the Statistical Package for Social Sciences 18.0 (SPSS Inc, Chicago, IL). The VHI and V-RQOL showed that the teacher and singer group were significantly higher than those of the control group in functional, physical and emotional aspects(p<0.05). the acoustic analysis using CSL 4500 showed the teacher and singer group were significantly higher than those of the the control group in fundamental frequency related variables, fundamental perturbation related variables, amplitude perturbation related variables, noise related variable, and tremor related variables(p<0.05). Conclusionally, the teacher and singer group recognized their voice problems as a serious physico-functional aspects.

본 연구의 목적은 교사 및 성악가에 대한 음성장애지수(VHI), 음성관련 삶의 질 평가(V-RQOL), 음향음성학적 평가에 대한 특성을 연구하였다. 본 연구는 56명(성대결절이 있는 교사 20명 및 성악가, 그리고 정상화자 16명)을 대상으로 하였다. 모든 대상자에게 VHI, V-RQOL를 평가하였고, 음향학적 평가는 CSL 4500(Kay Pantax, USA)으로 측정하였다. 21명의 대상자에게 VHI, VRQOL, CSL을 이용한 음향적 평가에 대한 검사-재검사를 위해 두 번 실시하였다. 본 연구의 자료처리는 SPSS 18.0(SPSS Inc, Chicago, IL)을 사용하였다. 본 실험 결과, VHI 및 V-RQOL 결과, 교사 및 성악가 집단의 신체적, 기능적, 정서적 점수가 정상집단에 비해 유의하게 높았다(p<0.05). 음향학적 특성은 기본주파수 관련 변수, 기본주파수 변이 관련 변수, 음성강도 변이 관련 변수, 잡음 관련 변수, 진전 관련 변수) 범주에서 실험집단이 정상집단에 비해 유의하게 높았다(p<0.05). 결론적으로 교사 및 성악가들은 신체-기능영역에서 자신의 음성문제를 심각하게 인식하는 것 같다.
