1. Complications of Transcutaneous Protheses – A Systematic Review of Publications Over the Past 10 Years
Abstract Introduction Bone conduction implants, responsible for transmitting sound from an external processor to the inner ear, can be divided into active and passive, depending on the vibratory stimulus location. The use of transcutaneous device has increased, given its aesthetic appeal, the complications and limitations of percutaneous devices, and patien

3. High-frequency Audiometry Hearing on Monitoring of Individuals Exposed to Occupational Noise: A Systematic Review
Abstract Introduction The literature reports on high-frequency audiometry as one of the exams used on hearing monitoring of individuals exposed to high sound pressure in their work environment, due to the method́ s greater sensitivity in early identification of hearing loss caused by noise. The frequencies that compose the exam are generally between 9 KHz

4. Cochlear Implantation and Single-sided Deafness: A Systematic Review of the Literature
Introduction Current data show that binaural hearing is superior to unilateral hearing, specifically in the understanding of speech in noisy environments. Furthermore, unilateral hearing reduce oné s ability to localize sound. Objectives This study provides a systematic review of recent studies to evaluate the outcomes of cochlear implantation in patien

5. Active Bone Conduction Prosthesis: BonebridgeTM
Introduction Bone conduction implants are indicated for patients with conductive and mixed hearing loss, as well as for patients with single-sided deafness (SSD). The transcutaneous technology avoids several complications of the percutaneous bone conduction implants including skin reaction, skin growth over the abutment, and wound infection. The Bonebridge

6. Tinnitus Neural Mechanisms and Structural Changes in the Brain: The Contribution of Neuroimaging Research
Introduction Tinnitus is an abnormal perception of sound in the absence of an external stimulus. Chronic tinnitus usually has a high impact in many aspects of patients' lives, such as emotional stress, sleep disturbance, concentration difficulties, and so on. These strong reactions are usually attributed to central nervous system involv

7. Criação e performance musical no contexto dos instrumentos musicais digitais / Music creation and performance in the context of digital musical instruments
This work presents a study about the computer as an instrument for musical performance. Based on this study we developed processes of music creation using the algorithmic representation and the computer code. The two main technical resources we applied in our works were: a sound synthesis method based on the generation of waveforms by non-linear equations; a

8. Loudness scattering due to vibro-acoustic model variability
The use of numerical simulation in the design and evaluation of products performance is ever increasing. To a greater extent, such estimates are needed in a early design stage, when physical prototypes are not available. When dealing with vibro-acoustic models, known to be computationally expensive, a question remains, which is related to the accuracy of suc

9. An efficient GPU-based implementation of recursive linear filters and its application to realistic real-time re-synthesis for interactive virtual worlds / Uma implementação eficiente de filtros lineares recursivos e sua aplicação a re-síntese realistica em tempo real para mundos virtuais interativos
Muitos pesquisadores têm se interessado em explorar o vasto poder computacional das recentes unidades de processamento gráfico (GPUs) em aplicações fora do domínio gráfico. Essa tendência ao desenvolvimento de propósitos gerais com a GPU (GPGPU) foi intensificada com a produção de APIs não-gráficas, tais como a Compute Unified Device Architecture

10. 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

11. Complemental tests in semen and evaluation of the anionic proteins and peptides differentially synthesized in seminal plasma of Nelore bulls classified as sound and unsound for breeding / Testes complementares em sêmen e avaliação da síntese diferencial de proteínas e peptídeos aniônicos em plasma seminal de touros da raça Nelore classificados em aptos e inaptos à reprodução
The main analyses performed routinely to assess the sperm quality are the spermatic motility and morphology for the measurement bulls fertility. Several complementary techniques are used to improve bulls fertility evaluation. Each technique is related to different aspects of sperm quality and their results are not yet fully understood. Four experiments were

12. Soundscape design through evolutionary engines
Two implementations of an Evolutionary Sound Synthesis method using the Interaural Time Difference (ITD) and psychoacoustic descriptors are presented here as a way to develop criteria for fitness evaluation. We also explore a relationship between adaptive sound evolution and three soundscape characteristics: key-sounds, key-signals and sound-marks. Sonic Loc
