Background and Objectives : Singers, the vocal equivalents of Olympic athletes, may present with vocal dysfunction in the singing voice before adverse effects are noted in the speech mode. For the classically trained singers, any imbalance in the respiratory, laryngeal or resonatory subsystems may manifest first in technical compensations. Therefore it is necessary that baseline values be available in order to differentiate technique related dysfunction from abnormalities within the phonatory system. Materials and Methods : Vocal efficiency measures were collected from 55 classically trained singers and 20 untrained adults. All singers was divided into 3 groups : (1) Singers who have normal larynx with out voice symptoms. (2) Singers who have vocal nodule without voice symptoms. (3) Singers who have vocal nodule with voice complaints. Results and Conclusion : Results were compared with each other. Differences in each group wert found, suggesting the need for separate normative data to be used for the evaluation of the classically trained singers.

1) 음성 장애를 호소하지 않는 성악인 50명중 여자는 59% 남자는 50%에서 후두스트로보스코피상 성대 병변이 발견되었다. 2) 성종별로는 소프라노에서 가장 성대 병변의 발생률이 높았다(66.7 %). 3) 최장발성 지속시간은 성악인의 경우 성대 병변에 관계없이 일반 정상인에 비해서 증가되어 있었으며 특히 정상 성대를 가진 여자 성악인에서는 일반인에 비해 통계적으로 의의 있게 증가되어 있었다. 4) 기본진동수, 기본진동수 표준편차, 기본진동수변 이들은 성악인이 일반인에 비해 안정되어 있었고, jitter. PPQ는 성악인이 성대 병변이 있더라도 일반인에 비해 감소되어 있었으며, 특히 남자 성악인에서는 통계적으로 유의하게 감소되어 있었고, Shimmer. APQ 역시 성악인이 성대 병변이 있더라도 일반인에 비해 통계적으로 의의 있게 감소되어 있었다.

Background and Objectives : Voice therapy has been used as a viable adjuvant to surgery and pharmacological therapy fir the management of voice disorders. The singing voice features a special brand of emotion, intensity, and energy so successful therapeutical approach requires the doctor is able to involve himself into the physical and psychic condition and artistic usage of the voice. The purpose of this study was to evaluate the effect and utility of singing therapy as an initial treatment for classically trained singers with voice disorders. Material and method : Twenty-one male and fifty-five female classic singers with voice disorders were treated with singing therapy. At first, abdominal breathing, resonant phonation, and relaxation method was trained, then after accessing each patient's singing abilities, treatment methods for each specific problems was applied. The results were compared according to age, sex, treatment duration, part, laryngeal pathology, patient subjective evaluation, perceptual evaluation of voice, and maximal phonation time. Results : Patients subjective evaluation, perceptual evaluation, pathologic findings of larynx, maximal phonation time showed superior results after singing therapy. Conclusion : Singing therapy changes the mode of respiration and phonation and enhances the vocal function and improves the laryngeal pathology, The result of this study indicate that singing therapy is an effective treatment method that laryngologists can use for classical singers with voice disorders.

Vocal Register Transition(Passaggio) is one of the most important vocal technique for classically trined male singers(tenor). Passaggio is that it bridges the chest register to head register without a noticeable voice break. Vocalist gest the feeling that voice is not locked a particular register. The purpose of this study was to clarify the difference between easy($B_3$) tone and non passaggio(F#_4$) & passaggio(F#_4$). We selected 6 trained singers(tenor), who had more than 12.6 years of experience and were well trained in passaggio technique. Simulataneous measurement was performed frequency(F0), mean flow rate(MFR), intensity(I), and subglottal pressure(Psub) using a phonatory function analyzer(Nagashima) and Closed Quotient(CQ), Jitter, Shimmer, NHR a Electro-glottography(EGG) of Lx. Speech Studio(Laryngogrph Lt, London, UK) and vocal efficiency was calculated by Carroll's method. For the tenor, target tone/a/was measured in three conditions : 1) easy phonation : $B_3$, 2) high tone without passaggio : F#_4$, 3) high tone with passaggio : F#_4$). The results revealed that F0 of the target tones between non-passaggio group and passaggio group were not significantly different though higher is F0, higher is subglottal pressure. And also CQ, MFR, Psub were increased in passagio than nonpssagio but these values were not statistically different. This study concluded that passaggio is the vocal technique to make the same quality of tone between chest register and head register in tenor.
