1. Fuzzy Modeling of Annoyance Caused by Aircraft Noise Using Laeqd and Laeqn Metrics
ABSTRACT: Airport noise presents a major environmental impact arising from aircrafts airport activities, being one of the most complex and difficult mitigation problems. From the environmental point of view, airports cause serious problems to the population. Annoyance caused by noise was evaluated from the Day-Night Level (DNL) metrics proposed by Schultz. H

2. Análise da influência de parâmetros acústicos na inteligibilidade da fala: um estudo em salas de aula de escolas municipais de João Pessoa.
Researchs in the area of environmental comfort conducted in schools reported that, considering the thermophysical variables, the acoustic variable is more important than the other variables, especially in relation to thermal, luminous and indoor air quality variables, since this is the variable that is directly tied to speech intelligibility, with impacts on

3. Estudo do ruído de rodagem estrutural através da análise dos caminhos de transferência de energia - TPA / Structure-borne road noise study using transfer path analysis, TPA
The road noise, vibration and harshness (Road NVH) present from 20 Hz to 1000 Hz approximately, begins from the tires vibration and acoustic propagation and their interactions with the road surfaces. In these noise sources, both structural-borne and air-borne noise contributions are relevant to vehicle refinement. The constant efforts to study the vehicle as

4. Análise do conforto ambiental em salas de aula da Universidade Federal de Goiás / Analysis of environmental comfort in classrooms at the Federal University of Goias
Provide users good physical conditions in educational institutions is essential for the proper development of teaching and learning. This work deals with the verification in-loco of the environmental comfort of classrooms in two buildings with different architectural and construction techniques, that are part of the structure of the Federal University of Goi

5. Mechanical strength and thermal conductivity of low-porosity gypsum plates
The thermal conductivity and mechanical strength of gypsum and gypsum-cellulose plates made from commercial plaster by a new process have been measured. The gypsum parts made by the new process, 'novogesso', have high mechanical strength and low porosity. The gypsum strength derives from both the high aspect ratio of the gypsum crystals and the strong adhesi

6. Thermo-acoustic comfort of a low-cost housing / Conforto termo-acústico de uma habitação de baixo custo
The use of new technologies associated with new materials is a contribution to the building industry, decreasing the housing deficit and reducing the environmental impacts generated by traditional design techniques. These new materials are alternatives to the current shortage of materials for construction, which has raised the prices of construction in our c

7. Total comfort as a referential to the process of architectural project / O conforto pleno como referencial no processo de projeto arquitetonico
Never forsaking Art as the essence of Architecture, comfort in constructed environments is analyzed as the main implicit and explicit goal of any architectural project. Comfort is the explicit intention of architects in the visual-plastic aspects of their projects to the extent its impact on users behaviours is greater than other lesser architectural aspects

8. Materiais e técnicas contemporâneas para controle de ruído aéreo em edifícios de escritórios: subsídios para especificações / Contemporaneous materials and techniques to air noise control on corporate edifices: specification foundations
Big cities have been taken the ground thought freeways and avenues, where constant and loud noise takes place. At theses ways, corporate edifices are also often established, so they naturally become exposed to the external noise interference, regardless the own internal facilities noising. The consequence is that people how work at these places are more pron

9. Acoustic comfort level : a proposal for residential buildings / Nivel de conforto acustico : uma proposta para edificios residenciais
O desempenho de uma edificação envolve aspectos fundamentais, como conforto, segurança e durabilidade. Dentro desses aspectos, podem ser avaliados os confortos acústico e térmico, segurança contra incêndio e, resistência estrutural, aos agentes agressivos e à água. Muitas vezes é somente após a entrega do edifício que, ao item conforto, passa a

10. Hearing AID prescription based on audiometric thresholds and auditory steady state responses / Ajustes das características eletroacústicas do aparelho de amplificação sonora individual com base em limiares auditivos tonais e resposta auditiva de estado estável
The impossibility for obtaining behavioral auditory data in children with hearing loss brings the necessity of applying objective tests as auditory steady state responses (ASSR) in order to evaluate the auditory thresholds. The objective of this study was to verify the differences found on the selection of the eletroacoustic characteristics of the hearing ai

11. ESTUDO DE ALVENARIAS E REVESTIMENTOS DE GESSO RECICLADO DESTINADO À HABITAÇÃO POPULAR / Study of masonry and Coatings made by Recycled plaster for low cost housing.
The generation of large quantities of solid waste is a great problem faced by urban areas. Like all building materials, the gypsum plaster is a generator of solid waste. The amount and inadequate waste disposal cause serious environmental, social and economical impacts. This requires the search for quick and effective solutions for its management, through th

12. A integração dos aspectos de conforto ambiental no projeto de escolas : uso da metodologia axiomatica e de exemplos simplificados / Integration of environmental comfort aspects in school design : use of axiomatic design method and simplified design example
The post-occupation-evaluations of school buildings in the State of São Paulo show that most schools have problems caused by decisions made at the preliminary design stage. These problems particularly cause discomfort to users in educational and administrative areas of the schools. Many environmental comfort (thermal, acoustic and lighting) problems affect
