Abstract

Objectives: The pitch of the singing voice can be influenced by changes in vocal fold length and resonance space. The aim of the study was to investigate differences in singing biomechanics in relation to the cricothyroid joint (CTJ) type between professional singers (PS) and non-singers (NS).

Methods: We recruited 22 PS (all male; 11 tenors, 11 bass/baritones) and 20 NS (10 males and 10 females) and analyzed three-dimensional images of the larynx derived from high-resolution computed tomography (HRCT) scans obtained at the mean speaking fundamental frequency (F0) and one (F1) and two octaves (F2) above this pitch.

Results: Sixteen of the PS (72%) had a type A CTJ and 6 (28%) had a type B/C CTJ. From F0 to F2, vocal fold elongation was 18% in all PS and 10% in all NS. In PS with a type A CTJ, the vocal fold elongation was 20% over two octaves (F0-F1: 15%; F1-F2: 5%), and in PS with a type B/C CTJ the elongation was 11% (F0-F1: 7%; F1-F2: 4%). In NS, vocal fold elongation was 10% over two octaves regardless of the type of CTJ (F0-F1: 7%; F1-F2: 3%).

Conclusions: Male PS lengthen their vocal folds sufficiently in the first and second octaves, while NS do not lengthen them sufficiently enough to elevate the singing pitch. NS probably reduces the resonance space via laryngeal elevation in order to increase the singing voice.

环甲关节类型对专业男歌手与非歌手声带伸长的影响。

目的：声带长度和共振空间的变化会影响歌唱声音的音高。本研究的目的是探讨专业歌手（PS）和非歌手（NS）在歌唱生物力学方面与环甲关节（CTJ）类型的差异。方法：我们招募了22名男低音（均为男性，11名男高音，11名男低音/男中音）和20名男低音（10名男性和10名女性），并分析了在平均说话基频（F0）和一个（F1）和两个八度音阶（F2）上获得的高分辨率计算机断层扫描（HRCT）喉部的三维图像。结果：a型CTJ 16例（72%），B/C型CTJ 6例（28%）。从F0到F2，所有PS和NS的声带伸长率分别为18%和10%。在a型CTJ的PS中，两个八度的声带伸长率为20% (F0-F1: 15%; F1-F2: 5%)，而在B/C型CTJ的PS中，伸长率为11% （F0-F1: 7%; F1-F2: 4%）。在NS中，无论CTJ类型如何，两个八度内声带伸长均为10% （F0-F1: 7%; F1-F2: 3%）。结论：男性PS在第一、二八度的声带长度上有充分的延长，而NS的声带长度不足以提高歌唱的音高。NS可能是通过喉抬高来缩小共振空间，从而提高歌声。证据等级：4；
