Purpose: The effects of multichannel expansion on the objective and subjective evaluation of 20 listeners fitted binaurally with 4-channel, digital in-the-ear hearing instruments were investigated. Method: Objective evaluations were conducted in quiet using the Connected Speech Test (CST) and in noise using the Hearing in Noise Test (HINT) at 40,…

Discusses forthcoming EPIE kits that include techniques for evaluating and sources of information for selecting instructional materials and equipment. (JF)

A systematic study of all fixed wing pilot training programs at the U.S. Army Aviation School was conducted in fiscal year 1968. The objective was to determine whether training might be made more effective through greater use of synthetic flight training equipment and, if so, to specify the main characteristics of appropriate equipment. Secondary…

This paper describes the Vocal Demodulator as a new device for analysis of vocal tremor. The Vocal Demodulator produces amplitude-demodulated and frequency-demodulated outputs and measures the frequency and level of low-frequency tremor components in sustained phonation. The paper describes quantification of the demodulation process, validation…

A 2-microphone dereverberation technique was evaluated by obtaining speech recognition measures and preference judgments from 10 normal-hearing adults and 7 older adult hearing-impaired listeners. Both groups had higher scores at the shorter reverberation time than at the longer reverberation time. Hearing-impaired subjects performed significantly…

Describes a study using blind high school students and a repeated subject design to evaluate six selected sewing machines. The major purposes were to compare and analyze specific sewing machine features and to determine the machines' overall ease of performance when operated by blind students. (CT)

Both microfilm readers and reader-printers (RRP) for cartridge, roll, microfiche, and aperture card use are evaluated in this report. A method of selection is described which uses a seven-step procedure. The first step for a user is to fill out his requirements on a form which is provided in the report. The second step is to review the…

This author recommends a comprehensive evalution of education construction projects 11 months following their substantial completion, when users have had sufficient time to identify true weaknesses, original intentions have not been forgotten, shortcomings in materials or the construction process will have appeared, and one year warranties have…

This project was conducted April-May 1985 and involved 62 public service librarians. The evaluation goals were to involve the staff during the implementation of this new technology and to collect data on these objectives: to measure satisfaction with training, documentation, equipment, printing, and system reliability; to identify materials to be…

Questions are discussed concerning the problem of evaluating an educational product for its potential marketing success. A strategy is proposed for identifying various levels of evaluation for a product, and for selecting the evaluation level that will be accepted as yielding sufficient evidence for the desirability of marketing the product.
