A 3-year longitudinal study was conducted to investigate changes in vocal quality as a result of singing training at a tertiary level conservatorium in Australia. Singers performed a messa di voce (MDV) at intervals of 6 months over the 3-year period of training. The study investigated the evolving acoustic features of the singers' voices exhibited during the MDV, including sound pressure level (SPL), short-term energy ratio (STER), duration, and vibrato parameters of the fundamental frequency (F0), SPL, and STER. The maximum SPL exhibited a marginal systematic increase over the training period, but the maximum STER did not systematically change. F0 vibrato extent increased significantly, whereas the extent of SPL and STER vibrato did not change significantly.
一项为期 3 年的纵向研究旨在调查澳大利亚高等音乐学院的歌唱训练对嗓音质量变化的影响。在 3 年的训练期间，歌手每隔 6 个月进行一次弥撒（MDV）。本研究调查了歌手在 MDV 中表现出的声音的不断发展的声学特征，包括声压级（SPL）、短期能量比（STER）、持续时间以及基频（F0）、SPL 和 STER 的振颤参数。在训练期间，最大 SPL 表现出略有系统的增加，但最大 STER 并未系统地改变。F0 振颤幅度显著增加，而 SPL 和 STER 振颤幅度则没有显著变化。
