This paper reports on an effort to create a network of both developers and users of a public health information system. Through an analysis of capacity, recruitment, and power in the network, issues related to choice of technologies, global-local tensions, and parameters of institutional collaboration, we illustrate a number of challenges. Comparing OSS principles to a "Networks of Action" appr...

The Effects of Room Acoustics on Auditory Spatial Cues The signals reaching the listener’s ears directly from a sound source convey information about the source’s location (Blauert 1997; Schnupp et al. 2010). However, in ordinary settings, soon after the direct sound reaches the listener, reflected sound arrives from random directions, coming off of walls, floors, and other reflective surfaces....

BACKGROUND Annoyance reactions to environmental noise, such as wind turbine sound, have public health implications given associations between annoyance and symptoms related to psychological distress. In the case of wind farms, factors contributing to noise annoyance have been theorised to include wind turbine sound characteristics, the noise sensitivity of residents, and contextual aspects, suc...

In this paper, we propose an original method to include spatial panning information when converting monophonic recordings to stereophonic ones. Sound sources are first identified using perceptually motivated clustering of spectral components. Correlations between these individual sources are then identified to build a middle level representation of the analysed sound. This allows the user to de...

Sound information in video plays an important role in constructing audience experience. On the other hand, there are many circumstances where the audience cannot watch video with sounds. Subscripts are conventionally used as visual aids to provide the missing sound information. However, conventional subscripts are far less expressive for non-verbal sounds since it is designed to visualize speec...

With the rapid growth of both Internet and Multimedia the subject of hidden exchange of information has gained a great importance. The current work is based on translation of information of a digitized image into a sound file. Later the image file can be retrieved by authorized personnel by performing the reverse process on the sound file. The three dimensional RGB image matrix is converted int...
