This study aims to investigate the relationship between the anterior cricothyroid (CT) space at rest with vocal range in female singers. Potential associations with and between voice categories, age, ethnicity, anthropometric indices, neck dimensions, laryngeal dimensions, vocal data along with habitual speaking fundamental frequency were also explored.
This is a cohort study.
Laryngeal dimensions anterior CT space and heights of the thyroid and cricoid cartilages were measured using ultrasound in 43 healthy, classically trained, female singers during quiet respiration. Voice categories (soprano and mezzo-soprano), age, ethnicity, weight, height, body mass index, neck circumference and length, anterior thyroid and cricoid cartilage heights, practice and performance vocal range, lowest and highest practice and performance notes along with habitual speaking fundamental frequency were collected.
The main finding was that mezzo-sopranos have a significantly wider resting CT space than sopranos (11.6 mm versus 10.4 mm; P = 0.007). Mezzo-sopranos also had significantly lower "lowest and highest" performance notes than sopranos. There was no significant correlation between the magnitudes of the anterior CT space with vocal range. The participants with the narrowest and widest anterior CT space had similar vocal ranges.
These results suggest that the CT space is not the major determinant of performance vocal range.
本研究旨在调查女性歌手静息时环甲膜前部（CT）间隙与音域之间的关系。还探讨了嗓音类别、年龄、种族、人体测量指标、颈部尺寸、喉部尺寸、嗓音数据以及习惯性说话基频之间的潜在关联。
这是一项队列研究。
在43名健康的、接受过古典声乐训练的女性歌手安静呼吸时，使用超声测量喉部尺寸、CT间隙前部以及甲状软骨和环状软骨的高度。收集嗓音类别（女高音和女中音）、年龄、种族、体重、身高、体重指数、颈围和颈长、甲状软骨和环状软骨前部高度、练习和表演音域、最低和最高练习及表演音符以及习惯性说话基频。
主要发现是，女中音静息时的CT间隙比女高音明显更宽（11.6毫米对10.4毫米；P = 0.007）。女中音的“最低和最高”表演音符也明显低于女高音。CT间隙前部的大小与音域之间没有显著相关性。CT间隙前部最窄和最宽的参与者音域相似。
这些结果表明，CT间隙不是表演音域的主要决定因素。
