Abstract

The purpose of this study was to compare voice parameters in auditory conditions (normal/noise/music) between a teacher group and a control group. Results of statistical analysis showed that the teacher group had higher jitter (%) and shimmer (%) values than the control group. It indicated that the teacher group had larger variations in pitch and dynamic of their voice. In the teacher group, the voice under noisy condition showed a higher value of fundamental frequency than that under normal condition. though its fundamental frequency did not show any significant difference between the noisy condition and the musical condition. In the control group, however, although the voice under noisy condition also showed a higher value of fundamental frequency than that under normal condition, its fundamental frequency was significantly different between the noisy condition and the musical condition.

본 연구는 교사와 일반인을 대상으로 그들의 음성과 청각 조건 ( 소음, 음악 )에서의 음성 파라미터들을 비교 분석하여 다음과 같은 결과를 얻을 수 있었다. 교사는 일반인의 음성 보다 높은 주파수 변동률(%)과 진폭 변동률(%)을 보여 정상 음성에 비해 높이와 강도에 변화가 큰 것을 알 수 있었다. 청각 조건에 따른 결과를 살펴보면, 교사의 음성 파라미터는 청각 조건이 주어지지 않은 일반 음성에 비해 소음 환경에서 높은 기본 주파수 (Hz)를 나타내었고 소음과 음악 환경간에는 그 차이를 발견할 수 없었다. 일반인의 음성 파라미터 청각 조건이 주어지지 않은 일반 음성에 비해 소음 환경에서 높은 기본 주파수를 나타내었으며 음악과 소음 환경간에도 기본 주파수의 차이를 나타내었다.
