Describes acoustic analysis of the speech of a child from 46 to 149 weeks in which overall word duration, pitch perturbation, and within-word phonetic segments were measured. The subject's overall word duration decreased considerably at a relatively late stage, supporting the claim that a child's neuromuscular control improves with maturation.…

The average FM advantage over a personal hearing aid was equivalent to a 15dB improvement signal-to-noise-ratio (S/N). The benefit offered by the FM system decreased as the environmental signal-to-noise-ratio increased but remained significant even at +15dB. Significant improvement was also found with directional as compared to omnidirectional…

The accent in this article was on current educational techniques designed to encourage children to explore the dimensions of sound. Numerous activities for the classroom were offered, especially in the area of improvised vocal sounds and word transformation. (Editor/RK)

This standards publication provides acoustical performance criteria, design requirements, and design guidelines for new school classrooms and other learning spaces. The standards may be applied when practicable to the major renovation of existing classrooms. These criteria, requirements, and guidelines are keyed to the acoustical qualities needed…

Although the educational audiologist is a newcomer to the educational enviroment of hearing impaired children, he provides such essential services as adapting or modifying audiological tests and techniques traditionally used in clincial settings, thus more adequately defining and supplying acoustic needs.

Examines the relationship between illusory changes of repeated words (verbal transformations) and illusory presence of phonemes replaced by noise (phonemic restorations); paper presented at the 82nd meeting of the Acoustical Society of America, Denver, Colorado, October 1971, and supported in part by a University of Wisconsin-Milwaukee Graduate…

The work reported in this study attempts to further isolate the place of two codes of information, visual and acoustic. (Author/RK)

Discusses the development of musical thought in China. (RK)

Describes a student laboratory project involving the design of an "acoustic suspension speaker system. The characteristics of the loudspeaker used are measured as an extension of the inertia-balance experiment. The experiment may be extended to a study of Stelmholtz resonators, coupled oscillators, electromagnetic forces, thermodynamics and…

Cites realistic advantages afforded by inflatable structures when used in physical education programs. (LN)
