Abstract in Portuguese
O presente trabalho tem como objetivo apresentar uma revisão bibliográfica de alguns dos principais conceitos acústicos e psicoacústicos associados à audição humana já desenvolvidos na literatura, de Helmholtz aos dias atuais, com foco no órgão da cóclea, relacionando as áreas de física, neurociências e computação musical, bem como aplicações diretamente derivadas de tal revisão. A partir dos cálculos realizados por Couto (COUTO, 2000) de distribuição da pressão sonora no meato acústico externo, foi calculada a pressão sonora relativa e a impedância acústica ao longo do órgão coclear. Também é apresentado um algoritmo de minimização da dissonância sensorial baseado nos modelos de bandas críticas de Cambridge e de Munique.

Abstract in English
The present work presents a literature review on some of the most important acoustical and psychoacoustical concepts associated to human hearing, from Helmholtz to the present day, focusing on the cochlea and connecting concepts of physics, neurosciences and computer music, as well as applications directly derived from such concepts. From the sound pressure distribution model developed by Couto (COUTO, 2000), the relative sound pressure and the acoustic impedance along the cochlea were calculated. An algorithm for minimizing sensory dissonance based on Cambridge and Munich models of critical bandwidths is also presented.
