This study consists of two experiments. Pitch, volume, and tempo in auditory-haptic geographic information systems were compared in terms of effectiveness for multimodal interface; volume was determined to be better. Auditory display with volume and haptic display with vibration were compared and the results showed that, in more complex geographic…

In this article, we report on our qualitative study involving eight individuals hired to transcribe research tapes in university contexts. We consider issues of data analysis and data trustworthiness and the implications for both when transcription is assigned to someone other than the researcher. We explore the challenges transcribers faced…

Lectures can present barriers to learning for many students and although online multimedia materials have become technically easier to create and offer many benefits for learning and teaching, they can be difficult to access, manage, and exploit. This article considers how research on interacting with multimedia can inform developments in using…

One of the ways to improve the reliability in perceptual voice quality rating is to provide listeners with external anchors. A paired comparison matching paradigm using synthesized Cantonese voice stimuli that covered a range of rough and breathy qualities were used to investigate the rating reliability. Twenty-five speech pathology students rated…

Regardless of the extremely subtle acoustic changes that are perceptible within almost all perception research studies, it is the total overall effect that generally occupies each individual listener. A long line of research indicates that many subtle "music changes" are often not perceived accurately and are actually mistakenly identified.…

Public radio is about to achieve a new technological level as the new Public Radio Satellite System (PRSS) is deployed. The network will dramatically improve the capacity and quality of its interconnection system, but proper interfacing at member stations will be required to realize the full benefits of the new system. The new system uses digital…

As digital audio evolves, it is only natural that college radio stations reflect the same industry standards. Managers of college radio stations are facing the dilemma of making the decision of which digital audio system to acquire. A specific characteristic for those in the academic world is that whatever piece of equipment is chosen will be…

This is part I of a report on a study comparing reel and cassette tapes for signal-to-noise ration, total harmonic distortion, dynamic response, frequency response, bias and virgin noise and oxide coating uniformity. Test equipment and procedures are described and results are discussed. Charts detail research findings. (CHK)

Describes the principal modules of analog electronic music synthesizers and discusses some ways that a synthesizer has been used in demonstrations, in psychophysical experiments, and in an undergraduate laboratory course in the physics of music and acoustics. Considers the synthesis of both steady and transitory auditory phenomena. (Author/MLH)

This lecture explains the workings of automatic synchronization, the new ANSI standards, what they mean to program interchangeability, how to prepare a program, and how some rear screen and front projection equipment works. Its purpose is to show that personal slides can be shown as instructional material. (SC)

The current practice of Bolton College of Education, its relationship with other departments, problems of storage and retrieval are described and related to possible future developments. (Author)

CHARACTERISTICS OF 350 EDUCATIONAL AUDIO TAPE LIBRARIES IN PUBLIC SCHOOLS, COLLEGES, EDUCATIONAL RADIO STATIONS, AND OTHER FACILITIES THROUGHOUT THE COUNTRY WERE COMPILED BY TWO QUESTIONNAIRES AND VISITS TO SELECTED LIBRARIES. PERCENTAGE DATA WAS GATHERED ON TAPE ACQUISITION AND EVALUATION, CATALOGING, FINANCING, EQUIPMENT AND ENVIRONMENT, AND…

This manual is designed to assist students in a course on media in instruction and management. Units are included on: (1) still picture projection; (2) audio media; (3) motion picture projection; (4) print media, duplication, and displays; (5) selection of appropriate instructional materials; and (6) selecting appropriate media. Each unit includes…

To investigate impaired residual disciminiation for low-frequency formants and its influence on electronic compensation effectiveness, evaluations were made on impaired discrimination for speech formants, synthetic enhancement of consonants, wearable transposer aids, and a speech perception survey. Results showed that certain persons with severe…
