Synchronous Multimodal Measurements on Lips and Glottis: Comparison Between Two Human-Valve Oscillating Systems

Synchronous visualization of multimodal measurements on lips and glottis: comparison between brass instruments and the human voice production system

Session 3aMU: Aeroacoustics of Wind Instruments and Human Voice II 3aMU6. Synchronous visualization of multimodal measurements on lips and glottis: Comparison between brass instruments and the human voice production system

Brass instruments and the human voice production system are both composed of a vibrating "human valve" (constriction in a pipe) coupled to an acoustic resonator: lips coupled to the brass instrument or vocal folds coupled to the vocal tract. In both cases, the aeroacoustic coupling is responsible for the self-oscillations and a large variety of regimes. Additionally, brass instruments and voice...

[Data comparison on homicide deaths between two information systems, Brazil].

INTRODUCTION There is much criticism on the quality of criminal data available in Brazil, but there lacks systematic studies to corroborate it. Thus, it was conducted a comparison between homicides registered in Minas Gerais by two public information systems. METHODS The number of homicide deaths of the Mortality Information System of the Ministry of Health (SIM/MS) and Minas Gerais Military ...
