2. Controle ativo acústico estrutural: projeto, simulação e análise de qualidade sonora / Active structural acoustic control: design, simulation and analysis of sound quality
This master thesis deals with the study of active noise and sound quality control systems in automotive applications, and the innovative assessment of their performance based on relevant psychoacoustic metrics in this area such as Loudness, Roughness and Tonality. A methodology for designing and implementing active control systems based on psychoacoustic met

4. Intonational strategies in ensemble singing
The aim of the research was to find out about intonational strategies in the performance situation. The singing voice was chosen as the appropriate subject for experimental work, due to its superior capability to define pitch as compared to other musical instruments. Ensemble singing was also required, as harmonic context may be important in the clarificatio

5. Processos de composição microtonal por meio do modelo de dissonancia sensorial / Microtonal compositional processes via the sensory dissonance model
On the present research, Tuning Systems were studied in order to investigate its application in Creative Processes. For such, we created a distinction of compositional approaches in the music of the 20th Century, and we also studied mechanisms of scale development by mainly adopting Psychoacoustics (i.e. Roughness Model), which enabled the development of a c

6. Study of the audio coding algorithm of the MPEG-4 AAC standard and comparison among implementations of modules of the algorithm
Audio coding is used to compress digital audio signals, thereby reducing the amount of bits needed to transmit or to store an audio signal. This is useful when network bandwidth or storage capacity is very limited. Audio compression algorithms are based on an encoding and decoding process. In the encoding step, the uncompressed audio signal is transformed in

7. Behavioral, electroacoustic and electrophysiological assessment of hearing in autism. / "Avaliação comportamental, eletroacústica e eletrofisiológica da audição em autismo"
INTRODUCTION: Autism is a disorder, which begins in the infancy, and the main characteristics are the presence of an abnormal or impaired development of social interaction and communication, and restrict range of activities and interest. Some theories consider autism as a developmental disorder caused by a central nervous system alteration, and stress the pr

8. A musica no seculo vinte : estetica e psicologia
In our work we review and discuss the main paths of the musical and aesthetic revolution which took place in the twentieth century. Beggining with the advent offormalism, we focus on the ideas of composers and philosophers, until the post-war vanguard which culminated with Cage. Next, we focus on aspects of the cientific influence on music composition, mainl

9. Estudo das emissões otoacústicas e dos potenciais auditivos evocados de tronco cerebral em pacientes com zumbido. / Study of otoacoustic emissions and auditory brainstem response in patients with tinnitus
O zumbido (ou tinnitus) pode ser descrito como a percepção de um som ou ruído sem nenhuma estimulação acústica externa. Apesar de freqüente, ainda existem muitas dúvidas envolvendo o zumbido, no que se refere à sua origem e tratamento para a totalidade dos casos. Os objetivos do presente trabalho foram estudar a supressão das Emissões Otoacústica

10. Psychophysiology and psychoacoustics of music: Perception of complex sound in normal subjects and psychiatric patients
Perception of complex sound is a process carried out in everyday life situations and contributes in the way one perceives reality. Attempting to explain sound perception and how it affects human beings is complicated. Physics of simple sound can be described as a function of frequency, amplitude and phase. Psychology of sound, also termed psychoacoustics, ha
