From embouchure problems to embouchure dystonia? A survey of self-reported embouchure disorders in 585 professional orchestra brass players.
OBJECTIVES Data concerning embouchure problems in professional brass players are scarce. Embouchure problems can potentially lead to focal dystonia. The aim of this study was to investigate the frequency of distinct embouchure problems in professional brass players. Furthermore, the frequency of "cramping", a distinct symptom of embouchure dystonia, was evaluated in the context of established e...
متن کاملFrench horn embouchure: An electromyographic facial kinematic study
This study investigated embouchure-related muscle activities and related facial skin movement in trained French horn players. In relation to pitch and intensity of tone produced, amplitude of surface electromyogram (EMG) from five selected facial muscles and related facial skin kinematics were examined during preand post-attack phases. There was no difference in EMGs and facial kinematics betwe...
متن کاملAcousto-Refrigerator with an Adjustable Mechanical Resonator (RESEARCH NOTE)
Thermoacoustics describes energy conversion processes, activated by interaction temperature oscillation, accompanying the pressure oscillation in a sound wave, with solid boundaries. In ordinary experience this interaction of sound and heat cannot be observed, because of the very low temperature differences, but under suitable conditions, it can be emphasized and amplified to create remarkable ...

Jihn E. Kim Department of Physics and Astronomy and Center for Theoretical Physics, Seoul National University, Seoul 151-747, Korea DOI: http://dx.doi.org/10.3204/DESY-PROC-2010-03/kim jihn After showing the axion couplings, I review the Hawking type solution of the cosmological constant problem, present a (probably) correct way to calculate the probability amplitude, and show that the Kim-Kyae...
متن کاملOperator Adjustable Equalizers: An Overview
• References Introduction This paper presents an overview of operator adjustable equalizers in the professional audio industry. The term “operator adjustable equalizers” is no doubt a bit vague and cumbersome. For this, the author apologizes. Needed was a term to differentiate between fixed equalizers and variable equalizers. Fixed equalizers, such as pre-emphasis and de-emphasis circuits, phon...
