Abstract
OBJECTIVE
The present study aims at investigating the immediate effects of the Semi-Occluded Bubble Mask Technique (SOBM) performed with the device VocalFeel® as a vocal warm-up in a group of professional singers.
STUDY DESIGN
A randomized controlled study was carried out.
METHODS
Forty-four vocally healthy professional singers were randomly divided into two groups on recruitment: an experimental group and a control group. The same vocal warm-up exercise was performed by the experimental group with the SOMB technique and by the control group without semi-occlusion. Self assessments, acoustic analysis and aerodynamic analysis of Peak Nasal Inspiratory Flows (PNIF) and Peak Oral Inspiratory Flows (POIF) were performed.
RESULTS
Significant improvements after the SOBM technique were detected in the experimental group concerning some acoustic parameters (Jitt%; Shimm%) and aerodynamic measures (PNIF and POIF). No significant improvements after the warm-up exercise were observed in the control group. Significant differences between the experimental and the control group were found for ΔJitt%, ΔShimm%, ΔNHR, ΔPOIF and self assessments.
CONCLUSIONS
The results of the present study support the efficacy of a vocal warm-up performed with the SOBM technique using VocalFeel® device in terms of acoustic quality, aerodynamic measures and perceived phonatory comfort in professional singers.
