On-l ine quality control in automated welding operations is an important factor contributing to higher productivity, lower costs and greater reliability of the welded components. However, the development of on-l ine inspection techniques and feedback control is still in its infancy. Sound signature produced by GMAW contains information about the behavior of the arc column, the molten metal and ...

We examine the role of sound design in designing pervasive mobile games. As a case study, we examine the sound design process and solutions of a working prototype game called The Songs of North. The goal has been a design that allows sounds to be used as a primary information channel facilitating the use of physical movement as a main game mechanics. We discuss insights from the sound design pr...

For diagnosis of lung disease, lung sound auscultation plays an important role. Lung sound provides important information regarding underlying condition of lungs. Advances in the field of signal processing have led to development of automated tools for diagnosis of respiratory diseases using lung sound. This paper investigates the previous work undertaken by various researchers on automated res...

Sound symbolism refers to a non-arbitrary relationship between linguistic sounds and meanings. Sound symbolism has been discussed in relation to the ontogenesis of language. Our previous ERP study revealed that preverbal infants who are just about to start word learning show the N400 response to sound symbolically mismatched speech sound-visual shape pairs, suggesting that the infants detected ...

Sound event detection (SED) is the task of detecting the type and the onset and offset times of sound events in audio streams. It is useful for purposes such as multimedia retrieval and surveillance. Sound event detection is difficult in several aspects when compared with speech recognition: first, sound events are much more variable than phonemes, notably in terms of duration but also in terms...

This paper presents a system design and experimental evaluations for ambient sound-based proximity detection with smartphones. Ambient sound is useful as spatiotemporal identifier. This is because ambient sound contains abundant information which depends on time and space. To detect proximity at high accuracy, we calculate cross correlation in frequency domain for the similarity measure of ambi...

A simulator system to predict and hear road traffic noise was developed. The system places sound sources on vehicles in traffic flow simulation and reproduces sound data by using a three-dimensional sound capability. By using this system, the effect of road construction work and that of sound barriers as a countermeasure can be presented as easily-understood information; this capability should ...

This paper is a description of a pilot study that compared the relative effectiveness of three versions of a hypermedia system (Text, Sound/Text, Sound) designed to permit inservice teachers to learn instructional design from a computer. Analysis of the test data of twenty-seven participants showed that learning was greatest in the Sound version. Results of the interviews indicated that those w...
