Presents performance and purchasing information for audio-active and audio-passive headsets and for listening centers (junction box or wireless system), with charts of models, manufacturers, prices, and other specifications for the equipment. Includes advice on types of equipment for training use, mechanical factors, and safety considerations. (MF)

Localization acuity was examined by determining the smallest sound shift off midline and along the horizontal axis that infants 6-18 months could reliably discriminate. As their age increased, infants demonstrated a finer partitioning of auditory space along the horizontal axis. (PCB)

Examines two methods of generating synthetic speech in voice response systems, which allow computers to communicate in human terms (speech), using human interface devices (ears): phoneme and reconstructed voice systems. Considerations prior to implementation, current and potential applications, glossary, directory, and introduction to Input Output…

Discusses the content and success of an introductory general-studies physics course that emphasizes the theory and operation of hi-fidelity audio equipment. The course avoids traditional abstract mathematics and makes frequent use of classroom demonstrations and laboratory experiments. (MLH)

Communication is accomplished in many ways--through gestures, body language, writing, and speaking. Most people communicate verbally, without giving much thought to the process, but others may struggle to effectively communicate with others. The ability to express oneself affects behavior, learning, and sociability. When children are unable to…
