Nesta quinta-feira (09/05) o professor Scott Thomson, da Brigham Young University – EUA, fará uma palestra para o Departamento de Engenharia Mecânica (EMC). Ele trará uma síntese da sua pesquisa sobre biomecânica do sistema fonador humano e os processos de geração da voz. Os detalhes da palestra seguem abaixo.
Estudando a biomecânica da produção vocal usando modelos físicos e computacionais
Studying the biomechanics of voice production using physical and computational models
Resumo/Abstract
The human voice is produced by fluid-structure interactions between vocal fold tissue and air flow from the lungs. In our lab we use experimental and computational models of the vocal folds and upper respiratory airways to study voice production biomechanics and fluid-structure interactions. The experimental models are fabricated using silicone materials of different stiffness to represent the multi-layered structure of the human vocal folds. These experimental and computational models vibrate with amplitudes, frequencies, and vibration patterns similar to those produced by the human vocal folds. In this presentation, the models will be described and results from various experiments and simulations will be discussed.
Biografia/Bio
O Dr. Thomsom é professor do departamento de engenharia mecânica na Brigham Young University (BYU). Ele é graduado e mestre em engenharia mecânica pela BYU e PhD, também em engenharia mecânica, pela Purdue University. Desde que se tornou professor da BYU em 2004, leciona para estudantes de graduação em engenharia na BYU-Idaho e é professor visitante em Erlangen, Alemanha. O professor e seus estudantes pesquisam principalmente sobre biomecânica da produção vocal. Ele leciona para alunos de graduação e pós-graduação em sistemas de medição de engenharia, dinâmica dos fluídos computacional e fluídos experimentais.
