Listening tests play a crucial role in research and in the development of applications in room and building acoustics. Complementary to classical setups in which sound is presented to listeners via loudspeakers, advanced binaural auralisation tools nowadays allow for realistically presenting acoustic scenarios to listeners. In this work, we report on research results obtained by listening using both approaches, and the comparison between them. ...

© 2015 Published by Elsevier Ltd. This presentation introduces a didactic tool ArAc-Multibook of Architectural Acoustics (an interactive publication) whose main objective is to innovatively fill the gap in technical literature and to increase architects' awareness about the role acoustic comfort plays in the life of human beings. The ArAc project demonstrates an innovative approach to education and professional development of architects in the ...

Bad experiences with construction quality, the energy crises of 1973 and 1979, complaints about 'sick buildings', thermal, acoustical, visual and olfactory discomfort, the need for good air quality, the move towards more sustainability, all have accelerated the development of a field, which for a long time was hardly ...

The measurement of the sound reduction index R of building elements is typically performed according to ISO 10140, by measuring the sound pressure level in the sending and receiving room, using standardized loudspeaker-microphone instrumentation. Recent proposals for new building acoustic standards taking into account frequencies down to 50 Hz, provoke new questions. At low frequencies (depending on the dimensions of the rooms), the modal ...

The Wave Based Method (WBM) is used to predict the airborne and structure-borne sound insulation of building structures. In building acoustics, the frequency range of interest is 50-5000 Hz. Prediction models in building acoustics often assume infinite structures (like the transfer matrix method) or diffuse sound fields (statistical energy methods). These models cannot explain the inter-laboratory differences typically encountered in the lower ...

This book is intended for students of architecture and civil engineering and focuses on Environmental Acoustics in Architectural design. The focus lies on two main goals. (1) To provide a reasonable reduction of unwanted sounds, noise and vibrations (also called noise control) and (2) to ensure the most favourable conditions for generation, transmission and perception of desirable sounds (mostly speech or music) inside buildings or ...

Bad experiences with construction quality, the energy crises of 1973 and 1979, complaints about 'sick buildings', thermal, acoustical, visual and olfactory discomfort, the need for good air quality, the move towards more sustainability, all have accelerated the development of a field, which until some 40 years ago was hardly more than an academic exercise: building physics. Building physics combines several knowledge domains such as heat and ...
