Strategies for Safety Thresholds of Phonation for Performers via Dosimetry
Singers are among a category of professionals, along with many other professionals, who rely on their voice for work [1]. Phonotrauma can be caused by many factors, among which the amount and intensity of vocal use are at the forefront [2]. Dosimetry metrics can assist voice professionals aim for safe amounts of voice use, but a threshold of voice use has not yet been established and recommended by researchers [3].
Voice is Free After SOVT (Book Excerpt)
The beauty of SOVT exercises is that most of the beneficial effects occur simultaneously, without much voluntary adjustment or deliberate targeting. The system self-regulates. For example, high lung pressure produces a large vibrational amplitude, but high lung pressure with an SOVT also produces more vocal fold separation. de combined actions leave the contact stress regulated at a low value. d
Can the Production of Subharmonics in Vocalization be Considered a Form of Self-Organization?
Self-organization is the spontaneous formation of structures in space and/or time in systems composed of multiple components. Some form of overall order arises from local interactions between sub-system. The process occurs when sufficient energy is available in the system and nonlinearity exists in system components. No external control is needed. Unpredictable fluctuations in internal parameters, usually arising from nonlinearity, are amplified by positive feedback to bring about this organization. Chaos theory describes self-organization in terms of islands of predictability (attractors) in an otherwise unpredictable system.
Recent Insights into Vocal Injury in Singers
Vocal injury in singers can trigger a great deal of fear and uncertainty. A sudden change in the voice during or after a performance may raise the specter of a career-ending injury in the mind of the singer, and a voice that does not recover in due time can directly impact a singer’s livelihood. Much of the misgivings surrounding vocal injuries are attributable to a lack of accurate medical information on the nature of vocal injuries, how they are treated, and real-world outcomes. Several papers in the recent scientific voice literature shed light on these issues and may alleviate the singer’s concerns.
Air Pressures That Are Critical in Vocal Fold Vibration
As singers and speakers, we care about efficient ways to use our voices. Questions regarding the effective use of air pressure and airflow arise. For example: To get louder, is it just about pushing harder with more lung pressure? Or, are there other ways to tune up the system to get more bang for the buck? Let’s get some insights into various pressures in our airways.
