Vocal warmup is generally accepted as vital for singing performance. However, only a limited number of studies have evaluated this effect quantitatively. In this study, we evaluated the effect of vocal warmup on voice production, among young female singers, using a set of acoustic parameters. Warmup reduced frequency-perturbation (p < 0.001) and amplitude-perturbation values (p < 0.05). In addition, warmup increased singer's formant amplitude (p < 0.05) and improved noise-to-harmonic ratio (p < 0.05). Tone-matching accuracy, however, was not affected by warmup. The effect of vocal warmup on frequency-perturbation parameters was more evident among mezzo-soprano singers than it was among soprano singers. It was also more evident in the low pitch-range than in the higher pitch-ranges (p < 0.05). The results of this study provide valid support for the advantageous effect of vocal warmup on voice quality and present acoustic analysis as a valuable and sensitive tool for quantifying this effect.
声乐热身通常被认为对歌唱表演至关重要。然而，仅有有限的研究对这种效果进行了定量评估。在本研究中，我们使用一组声学参数评估了声乐热身对年轻女性歌手发声的影响。热身降低了频率微扰（p < 0.001）和幅度微扰值（p < 0.05）。此外，热身增加了歌手共振峰幅度（p < 0.05）并改善了噪声与谐波比（p < 0.05）。然而，音高匹配准确度不受热身影响。声乐热身对频率微扰参数的影响在女中音歌手当中比在女高音歌手当中更为明显。在低音域也比在高音域更为明显（p < 0.05）。本研究结果为声乐热身对嗓音质量的有益效果提供了有效支持，并将声学分析作为量化这种效果的一种有价值且灵敏的工具。
