Since the elevator muscles can generate forces that are ten times greater than those generated by the depressor muscles, the mechanical advantage gained through the use of depressor muscle is limited.
This appliance relies on the patients depressor muscles to depress the mandible.
According to videoendoscopy, other parts of the vocal mechanism often show oscillations in sync with the vibrato, including: (1) laryngeal depressor muscles, such as the sternothyroid and sternohyoid muscles; (2) the lateral pharyngeal wall; (3) the velum or soft palate; (4) the base of the tongue; (5) and the epiglottis.
The purpose of this research was: 1) to discover if surface electrode EMG is a reliable indicator of the activity of the laryngeal depressor muscles; 2) to test the usefulness of EMG biofeedback in teaching singers to activate the laryngeal depressor muscles and to maintain the lower laryngeal posture while singing; and 3) to determine if the achievement of said laryngeal posture improves the perceived quality of the sung tone, or changes any scientifically measureable components of the sound spectrum.
