A case study of the development and installation of a new music listening system at Central Washington University. (STS)

Guidelines for selecting duplicating audiotapes are presented with a discussion of the types of duplication techniques, advantages of an audiotape duplicator, and bases for evaluating audiotape duplicators. A chart featuring the characteristics of nearly 50 models of audiotape duplicators is included. (EC)

This paper describes an electronic guidebook, "Sotto Voce," that enables visitors to share audio information by eavesdropping on each others guidebook activity. The first section discusses the design and implementation of the guidebook device, key aspects of its user interface, the design goals for the audio environment, the eavesdropping…

Investigation of the effects of frequency range, harmonic distortion, intermodulation distortion, and transient response of hearing aids upon judgments of quality showed transient response measurements the best predictor of listener judgments, with voice a possible factor. (Author/KW)

Describes how audio technology is being integrated into CD-ROMs to create multimedia products. Computer hardware and software are discussed, including the use of HyperCard to combine still pictures, moving video pictures, and sound; and specific new multimedia products produced by the Voyager Company are described. (LRW)

Discusses the planning and decision-making process in acquiring sound equipment for sports stadiums that will help make the experience of fans more pleasurable. The bidding process and use of consultants is explored. (GR)

Addresses the potential benefits of using sound in computerized assessments. Describes some current computer uses of the audio channel of communication and outlines a proposed audio computer-based testing framework.

Real-time spectrographic displays (SDs) have been used in speech training for more than 30 years with adults and children who have severe and profound hearing impairments. Despite positive outcomes from treatment studies, concerns remain that the complex and abstract nature of spectrograms may make these speech training aids unsuitable for use…

Purpose: The present study was a methodological study designed to reveal the dynamic mechanisms of phonation instability pressure (PIP) using bifurcation analysis. Phonation pressure range (PPR) was also proposed for assessing the pressure range of normal vocal fold vibrations. Method: The authors first introduced the concept of bifurcation on the…

This study is part of the German Language Development Study's prospective longitudinal research programme on infants from birth until the age of 3 years. Thirty-four infants were retrospectively classified into two groups (normal/delayed) by their language skills at 2.5 years of age. Frequency spectrograms and melodies of about 11,000 cries from…

Recording lectures and making it available as MP3's might seem counterintuitive for a course that denies students the use of paper and pencil. The author speculated that online technology might help students get away from writing and allow them to think and learn in new (or perhaps older) ways. As with any other technological invention, it is…

This investigation, which employed a modified quasi-experimental approach, was undertaken to understand usage patterns in instructional podcasting and the impact of instructional podcasting on students and their performance in a community college setting. The experimental course sections included in the pilot study were taught in the fall of 2007.…
