Background and Objectives : The Voice Range Profile(VRP) is a two-dimensional graphic dysplay of an individual's amplitude range as a function of total fundamental frequency range. It is designed as a maximum performance test which can be used as a general indicator of voice problems in the non-professional voice and as a sensitive indicator of problems with the professional voice. The purpose of the study is to obtain a baseline VRT for the classical professional singers and compare it with the normal nonsinger's profile. We also compared the difference of VRP between the classical professional singers who have normal vocal fold and who have vocal folds lesions without dysphonia. Materials and Methods : The VRPs were elicited. from 42 trained classical singers(Soprano 26, Mesosoprano 5, Tenor 9, Bariton 2) and 20 untrained nonsingers(female 10, male 10) using Voice Range Profile Model 4326(Kay Elemetrics USA). The mean values for phonational range with highest and lowest pitch level and range of voice intensity with maximum and minimum intensity level were compared between classical singers and nonsingers. Results and Conclusions : The frequency range and dynamic range were significantly increased for the classical singers in comparison to the nonsingers. But there was no significant difference were found for the VRP between the parts in the classical singers. The classical singers who have vocal fold lesions showed slightly decreased VRP compared to those with healthy vocal folds.

Background and Objectives : Aerodynamic investigation is valuable information about the efficiency of the larynx in translating air pressure to acoustic signal. The normal data of the Korean has been reported, but there is no basic data of professional western classical singers who have learned how to control the flow of expiratory air for singing. The purpose of this study was to investigate the normal aerodynamic data of korean professional western classical singers and compare this with that of the Korean Materials and Methods : 50 Korean western classical singers were studied. Expiratory lung pressure combined with measurements of the mean air flow rate, voice frequency and intensity were measured with the aerodynamic test using airway interruption method. These data were compared with normal data of untrained normal adults. Results and Conclusions : The voice frequency and the voice intensity were increased in the western classic singers, but the mean air flow rate and the expiratory air pressure of the classical singers were within the same range of the untrained normal adults. This result means that western classical singers can change the loudness and pitch with a little increased or decreasing the mean air flow and the expiratory air pressure.

Trained singers, one group of professional voice users, have much more interest on the voice than common people, and on its management, too. They train for singing beautiful songs, and, at the same time, try for efficient voice production. The present study was performed with three tenors and three baritones, undergraduate students majored in classical singing, to investigate the degree of improvement of their voice production efficiency through vocal function exercise, by measuring the three dependent variables, maximum phonation time, speed quotient of glottal contact, and the number of semi tones. For the baseline establishment, dependent variables were measured 3$\sim$6 times for two weeks. Then, the subjects exercised vocal function exercise for seven weeks, and after the termination of training, evaluation was performed four times for two weeks, to find the maintenance of the training effect. Vocal function exercise is composed of four successive steps: warm-up, stretching exercise, contracting exercise, power exercise. As results, all of six subjects showed improvement in the aspect of maximum phonation time, speed quotient if glottal contact, and the number of semitones.

성악과 실용음악 간에 추구하는 노래와 발성의 차이로 인해 이들의 음성위생에 대한 지식과 수행하는 수준은 다를 수 있다. 본 연구는 대학교에서 성악 또는 실용음악을 전공하는 대학생 121(성악전공생 58, 실용음악전공생 63)명을 대상으로 음성위생 지식과 수행을 비교하였다. 또한 음성위생 지식과 수행 정도와 주관적 음성평가 간의 상관성을 살펴보았다. 연구결과, 음성위생 지식과 수행 모두 성악전공생이 실용음악전공생에 비해 유의하게 높았으며, 전체 집단에서 음성위생 수행이 지식에 비해 유의하게 높은 점수를 보였다. 또한 음성위생 지식과 수행 정도는 낮은 양의 상관관계를 보였고, 음성위생 수행과 주관적 평가는 낮은 음의 상관관계를 보였다. 본 연구를 통해 성악전공생에 비해 실용음악전공생이 음성위생 지식과 수행 정도가 상대적으로 낮다는 것을 알 수 있다. 또한 성악전공생과 실용음악전공생 모두 특정 음성위생 항목에 대한 지식과 수행수준이 낮아 이들에게 맞는 맞춤형 음성위생 교육프로그램을 제공할 필요가 있음을 밝혔다.
