1. Aperfeiçoamentos no código computacional RAIOS incluindo aurilização / RAIOS computer code improvements including auralization
In this work, the most important improvements implemented in the computer code of numeric simulation of room acoustics, called RAIOS, are presented. These improvements are divided in four groups: Data importation process from DXF les; implementation of new acoustic quality parameters and steady state sound pressure level calculation; modications in order to

2. Use of Component Mode Synthesis and Axial Splits in Ducts for Noise Control of Higher Order Duct Mode / Utilização de síntese modal de componentes e particionamento axial de dutos para controle dos modos acústicos de alta ordem
In this study, the proposal of this work is centered in the noise reduction in ducts that became, over the years, a field of intense application. The traditional approach to acoustic noise control in ducts uses passive techniques and fixed reactive silencers to mitigate the noise. In this moment, the Active Control of Noise (ANC) is an attractive approach to
