1. Childhood Hearing Health: Educating for Prevention of Hearing Loss
Introduction The presence of noise in our society has attracted the attention of health professionals, including speech-language pathologists, who have been charged along with educators with developing hearing conservation programs in schools. Objective To describe the results of three strategies for awareness and hearing preservation

2. CARACETERIZAÇÃO ACÚSTICA DE SALAS PARA PRÁTICA E ENSINO MUSICAL / ACOUSTIC CHARACTERIZATION OF ROOMS FOR MUSIC PRACTICE AND TEACHING
O músico necessita perceber adequadamente o som nos recintos onde atua, seja em ambientes destinados à performance, seja em ambientes destinados ao estudo e prática musical. Para que isto seja possível é necessário que estes locais estejam acusticamente adequados, permitindo o desenvolvimento e aprimoramento da percepção sonora musical. No presente t

3. Coeficiente de espalhamento sonoro de painéis perfurados / Scattering sound coefficient of perforated panels
Project studios, concert halls, theaters or places that require quality acoustics for musical activities, require studies on its volume, shape and composition of their surfaces, in order to achieve a place that fulfills its function acoustics. In cases where the volume and shape of these rooms are already defined, it is the acoustic designer to define materi

4. 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

5. AcMus: an open, integrated platform for room acoustics research
This article describes the design, implementation, and experiences with AcMus, an open and integrated software platform for room acoustics research, which comprises tools for measurement, analysis, and simulation of rooms for music listening and production. Through use of affordable hardware, such as laptops, consumer audio interfaces and microphones, the so

6. Caracterização acustica de ginasios de esportes multifuncionais da cidade de Campinas, SP / Characterization acoustics multipurpose gymnasium of sports of the Campinas s city
Similar sonorous stimulus may promote different sound perceptions in the environment. Sonorous stimulus may be objectively evaluated by acoustic measurements however, sound perceptions evaluation (subjectively) requires another specific methods. Spaces like sport gymnasiums can promote different sensations for the users depending on their activities. This ty

7. Hybrid method for numerical simulation of room acoustics with auralization: part 1 - theoretical and numerical aspects
A new hybrid simulation method for room acoustics is presented. It is grounded on two well known numerical simulation techniques for room acoustics. The hybrid method takes geometric acoustics for granted and uses an improved version of the classical ray-tracing technique for computing the specular reflections and a slightly modified energy transition method

8. Hybrid method for numerical simulation of room acoustics: part 2 - validation of the computational code RAIOS 3
In the companion paper "Hybrid method for numerical simulation of room acoustics with auralization: Part 1- Theoretical and numerical aspects" a new hybrid method for numerical simulation of room acoustics, implemented by the software RAIOS 3, was presented. Here, the software itself and its main features are discussed. It will be shown that the proposed met

9. Acoustical evaluation by impulsive technique of eight rooms used for theatrical presentation in the city of Campinas, SP / Avaliação acustica de oito salas destinadas a apresentações teatrais da cidade de Campinas, SP, atraves da tecnica impulsiva
The architectural acoustics is an issue related to environmental comfort and, as such, of great importance for the quality of the space, concerning the satisfaction level of its user. Among the wide range of edification typologies, the theaters excel for their acoustic quality, since they are destined essentially for the transmission of spoken sound messages

10. Desenvolvimento de um "phantom" para treinamento de biopsia de mama guiada por ultra-som / Phantom for Breast Biopsy Training Guided by Ultrasound
The main aim of work was the construction and characterization of acoustics proprieties of a prototype of phantom for the training of the breast biopsy guided by ultrasound. An important property of this phantom is its capacity of being thermically rebuilt after punctuated during the training and/or suffered any mechanic damage. For this purpose, a recycling

11. Perceptually relevant parameters for virtual listening simulation of small room acoustics
Various physical aspects of room-acoustic simulation techniques have been extensively studied and refined, yet the perceptual attributes of the simulations have received relatively little attention. Here a method of evaluating the perceptual similarity between rooms is described and tested using 15 small-room simulations based on binaural room impulse respon
