VOICE and the aerodynamics
The voice and aerodynamic
If an opera singer has a repertoire outside of his position, what Most often, they damage their vocal cords. Voice Laboratory at the University Clinic of Navarra analyze voice aerodynamic criteria to avoid the appearance of lesions.
When a man speaks his strings vibrate 100 times per second, when does a woman do it 280 times. "A singer can reach frequencies between 2,000 and 3,000 Hz. This pounding can cause injury if not done in a proper way," said Secundino Fernández, head of the Voice Laboratory at the University Hospital of Navarre, who together with Mary Uzcanga, the same unit, have been analyzed from the aerodynamic point of view the physiological mechanisms involved in the voice of lyric sopranos.
"The voice is pressurized air passing through the vocal cords deforming the mucosa, which produces sound. It is enriched, filtered modulated and resonant cavities."
Navarre team was examining how to sing opera professionals to see whether or not damage your body phonetic: "With a mask register the flow, pressure and acoustic signals during the singing, and by electrodes is controlled by the contact surface of the vocal cords. " The singing teacher shows various exercises and equipment to the University Clinic of Navarra records the results which are then analyzed.
A proper vocal technique prevents injuries among practitioners of bel canto. If the artist's repertoire does not fit your voice tessitura force, which can cause edema in the vocal cords, singer's nodules and small hemorrhages: "With these injuries must correct vocal technique and repertoire. Today there are few singers who drop by a vocal cord injury, even so, it is important to be measured regularly to detect any problem. "
The vocal apparatus of a soprano or a tenor does not differ essentially from that of any other person. "There are important anatomical differences and normal larynx. What distinguishes them is their vocal technique. Singers exceptional addition to a healthy larynx other aesthetic aspects that make a difference sense of drama, power of expression, musical aesthetics and heard. "
The voice, an instrument
The human voice is a great wind instrument. Its most noble are the vocal cords, but it would be impossible to make sound bellows: "You sing with your whole body. A good tenor or soprano hips should be positioned well, settle to the ground, using abdominal and diaphragmatic muscles and the jaw drop. "
The team from the University of Navarra has also considered how to adapt to the treble singers: "Not all artists can reach frequencies over high as the C's. We wanted to know what it depends on the treble. We have discovered that achieving this level depends on how they control the pressure and air flow. It is not something you learn easily. A soprano sings based on many bodily sensations and his own ear. The artist can control the intensity of air flow without increasing laryngeal resistance appears to be more prepared for the treble
