METHODS: This study is a comparative cross-sectional study.
METHODS: This study included 17 trained male Iranian traditional singers who were compared with 17 untrained ones who were matched in terms of age. The P-SVHI was completed by trained and untrained Iranian traditional singers. Measures of jitter, lowest intensity, highest phonational frequency, and maximum phonation time (MPT) were obtained from each participant. The DSI scores were calculated using these values.
RESULTS: Trained male traditional singers had an average age of 33.76 ± 7.45 years, 3.24 ± 1.85 hours of daily practice, 5.24 ± 3.78 years of training, 3.06 ± 2.65 no. of professional performances, and untrained singers had an average age of 32.76 ± 12.92 years, 1.53 ± 1.17 hours of daily practice, and 0.88 ± 1.65 no. of professional performances. Trained singers had lower P-SVHI scores and sub-scores, longer MPT, higher F0 high, lower jitter, and lower I low, resulting in higher DSI values (P < 0.05). There was no significant correlation between P-SVHI scores and DSI values in each group of trained and untrained Iranian traditional singers (P > 0.05).
CONCLUSIONS: The results of this study show that the vocal abilities of professional vocalists are enhanced through voice training (higher DSI scores in trained singers vs untrained ones). Voice training can also help to lessen the perception of a handicap related to the singing voice. Hence, it may be necessary to consider alternative norms for the DSI and P-SVHI when administering them to patients who have undergone guided vocal training, such as voice/singing lessons. The current research indicates that the perception of singing voice handicap and DSI values are two distinct characteristics that do not have a significant correlation.
方法:本研究为比较性横断面研究。
方法:这项研究包括17名受过训练的男性伊朗传统歌手,他们与17名未受过训练的歌手进行了年龄匹配的比较。P-SVHI由受过训练和未经训练的伊朗传统歌手完成。抖动的测量,最低强度,最高的语音频率,并从每个参与者那里获得最大发声时间(MPT)。使用这些值计算DSI评分。
结果:受过训练的男性传统歌手的平均年龄为33.76±7.45岁,3.24±1.85小时的日常练习,5.24±3.78年的培训,3.06±2.65号专业表演,未经训练的歌手平均年龄为32.76±12.92岁,每天练习1.53±1.17小时,和0.88±1.65没有。专业表演。受过训练的歌手有较低的P-SVHI分数和子分数,较长的MPT,较高的F0高,较低的抖动,降低I低,导致更高的DSI值(P<0.05)。各组经过训练和未经训练的伊朗传统歌手P-SVHI评分与DSI值无显著相关性(P>0.05)。
结论:这项研究的结果表明,通过语音训练,专业歌手的声乐能力得到了增强(受过训练的歌手与未受过训练的歌手相比,DSI得分更高)。声音训练还可以帮助减轻对与歌声有关的障碍的感知。因此,可能有必要考虑DSI和P-SVHI的替代规范,当他们给谁接受引导声乐训练的患者,如语音/歌唱课。目前的研究表明,歌唱嗓音障碍的感知和DSI值是两个不具有显着相关性的明显特征。
