Temporary threshold shift over a wide range of frequencies was found after 4 hours of hearing aid use by a 15-year-old student with severe sensorineural hearing loss who was using real-ear insertion gains 10 to 20 decibels greater than those recommended by current standards. Less gain was recommended at frequencies from 500 to 1500 hertz.…

The study evaluated use of the Modified Power Law to predict permanent threshold shift (PTS) resulting from noise exposure in eight children with severe sensorineural hearing loss attributed to overamplification by hearing aids. The PTS tended to be flat across frequency with its course similar to PTS in persons with normal hearing exposed to…

Suggests five criteria (media attrributes, costs, usability, serviceability, availability) to be used to assess justifiability of use of different types of high technology instructional media (HTIM) in Nigerian schools. Principal reasons for HTIM preference are outlined, and development and use of low technology instructional media to supplement…

Twenty students between the ages of 6 and 19 with profound to moderate hearing impairments were trained to monitor their own hearing aids and perform basic hearing aid maintenance tasks. Results indicated improved hearing aid function while students were actively involved in hearing aid maintenance programs but rapid decline of habits after…

This overview of computer uses in occupational training discusses three computer-based training modes--embedded, stand-alone, and adjunct training. An adjunct training system is described which captures task realism through a simulation to teach the use of a command and control system. A pilot study of this adjunct system's use is described.…

In this report the members of the Scientific Committee on Ocean Research Working Group 51 have attempted to describe the total process involved in obtaining salinity and temperature profiles with modern conductivity-temperature-depth (CTD) instruments. Their objective has been to provide a guide to procedures which will, if allowed, lead to the…

An increased proportion of Chapter 1 budgets across the country have been directed to the purchase of microcomputer hardware and software. A major reason for this expenditure has been the promise of better instruction, or at least more instruction for Chapter 1 students, without additional staff resources. Although evidence for instructional…
