Abstract-Text Objective: It is an old myth to predict the correct singing register based on the laryngoscopy. Short vocal folds (VF) are typical for sopranos, long VFs are typical for altos. It is obvious, that physical measureable parameters influence the voice range. The aim of this study was to analyse different anatomical parameters between professional sopranos and altos and to find out, if a multivariate measurement of anatomical parameters can predict the singing register.
Methods/design: We examined 49 professional female singers (25 sopranos, 24 altos). HRCT scan was performed during singing of F0 in each singer. DICOM scan data were rendered and 3D-visualized using the software MIMICS®. In all singers, we measured the length of the VF, of the glottis, the distance of the anterior commissure orthogonally to the vertebral spine and the antero-posterior distance of the trachea 1cm and 2cm below the glottis. In addition, the length and the volume of the resonance space was measured.
Results: We were able so measure all data in all singers. VF were measured 17.4mm (S) and 18.5mm (A), the glottis was 17.7mm (S) and 18.8mm (A), distance anterior commissure to vertebral spine was 28.4mm (S) and 30.0mm (A), the subglottic diameter 1cm below the glottis was 16.6mm(S) and 16.8mm (A) and 2cm below the glottis 15.0mm (S) and 14.5 (A). Logistic regression analysis yields positive predictive values of 79.3% for sopranos and 70% for altos respectively.
Conclusions: There are anatomical differences between sopranos and altos. The positive predictive value for sopranos is relatively good.
