There are many approaches to determine the sound propagated from turbulent flows.  In hybrid methods, the turbulent noise source field is computed or modeled separately from the far-field calculations.  To have an initial and quick estimation of the sound propagation, less computationally intensive methods can be developed using stochastic models of the turbulent fluctuations.   In this paper, ...

Background. A field study conducted by researchers found the balls used by visual impairment students at school basically used the sound by a small bell inside the ball. However, the sound emitted from the ball is very limited, the ball will sound when it is moved. This makes it difficult for students with visual impairments to find a missing ball that not emitted makes a sound. Objectives. A ...

In sound compression and synthesis, it is valuable to have objective distance measures which can predict the perceived dissimilarity of two sounds. Furthermore it is desirable also to be able to estimate the extent of the dissimilarity or the quality difference between sounds. Since it is the perceived difference that needs to be quantified it can be expected that measures that are derived from...

One of my early desires as a musician was to sculpt and organize directly the sound material, so as to extend compositional control to the sonic level to compose the sound itself, instead of merely composing with sounds. My use of the computer has focused mostly on this goal. I have been able to fullfill this desire to some extent by resorting to digital synthesis and also digital processing of...

Mathematicians who are blind must rely on non-visual representations of mathematical material. This paper describes sound-based representations which have been designed, implemented and evaluated as part of the development of a computer workstation for blind mathematics students. Particular emphasis has been on supporting synthetic speech with non-verbal cues, in the forms of the prosodic compo...

This note describes R&D to be carried out on the data acquisition system for a calorimeter at the future International Linear Collider. A generic calorimeter and data acquisition system is described. Within this framework modified designs and potential bottlenecks within the current system are described. Solutions leading up to a technical design report will to be carried out within CALICE-UK g...
