In 2003, Touch Graphics Company carried out research on a new invention that promises to improve accessibility to science museums for visitors who are visually impaired. The system, nicknamed Ping!, allows users to navigate an exhibit area, listen to audio descriptions, and interact with exhibits using a cell phone-based interface. The system…

This paper reports an action research study of teacher and pupil talk about composing. Data were collected through video and audio recordings of composition lessons in a secondary school. Qualitative analysis of the data led to the development of a "typology of pupil talk about composing" which distinguishes between six main types:…

Purpose: To investigate the effect of age on voice fundamental frequency (F[subscript 0]) difference limen (DL) and identification of concurrently presented vowels. Method: Fifteen younger and 15 older adults with normal audiometric thresholds in the speech range participated in 2 experiments. In Experiment 1, F[subscript 0] DLs were measured for…

This study investigated the effects of text notes and voice notes on the comprehension of science texts by fifth grade students. The study was conducted to determine whether digital note taking was an effective reading strategy, and whether one form of digital note taking was more effective than the other. Results revealed that general education…

Conference proceedings of the 25th Annual Conference on the Teaching of Psychology: Ideas and Innovations, sponsored by the Psychology Department of the State University of New York at Farmingdale. The conference theme for 2011 was: The Future of the Undergraduate Psychology Major: New Directions in an Evolving Educational Climate. The Conference…

Noting that a revolution in sonic high fidelity occurred during the 1980s as digital-based audio production methods began to replace traditional analog modes, this paper offers both an overview of digital audio theory and descriptions of some of the related digital production technologies that have begun to emerge from the mating of the computer…

To evaluate reel audio tape, tests were performed to identify: signal-to-noise ratio, total harmonic distortion, dynamic response, frequency response, biased and virgin tape noise, dropout susceptibility and oxide coating uniformity. (SCC)

Factors to be considered in purchasing various types of audiovisual equipment are outlined. (PF)

This final section of a three part article covers audiovisual furnishings, equipment, and systems not mentioned previously. (Author)

Tells what impedance is, and how it's measured, and how it affects cable length. (Author)

This brief introduction to the use of audiotape recorders in educational settings provides basic information on operational procedures and recording techniques for voice, music, dubbing, and pulsing. Audiotape editing and splicing are also explained. (RAO)

A proposal for a library project for mentally and physically handicapped persons at Custer State Hospital includes a listening library for the residents of the hospital with a cassette player in each resident's room. Tape storage would be at the nurse's station on each floor, and the charge nurse on that floor would be responsible for the tapes.…

Discussion of the parameters governing noise control and room acoustics are followed by a demonstration on how to achieve a good acoustical environment. Topics emphasized include--(1) design and control objectives, (2) noise sources and propagation, (3) reverberation parameters, (4) noise control factors and parameters, and (5) sound systems. Also…

A set of guidelines has been developed for the implementation of the audio mode in computer assisted instruction (CAI). The manual contains a collection of conventions and techniques synthesized from recent publications in areas pertinent to multi-media audiovisual presentation. These areas include audio message placement, positioning, frequency,…

There are several major areas with audio needs to be served: music, basic languages, literature, and general reference. These needs are most appropriately filled by the library, which is the best location for both audio production and services. (Author/MBR)
