This article discusses the species designation and taxonomies of Delaware and Algonkian and presents eight classifications of taxa by form, habitat, color, movement, sound, use, relationship, and appearance. Relevant research is also reviewed. (CLK)

Proposes a scientific methodology for investigation into corrective phonetics, making use of a phonologic roster to classify foreign realizations according to a linguistic pertinence criterion. (Text is in French.) (AM)

Memory for sequences of briefly presented letters was examined to discover the effects of intraserial repetition and acoustic contrast on recall of a critical letter pair. (Editor)

Describes the basic acoustical principles of percussion instruments whose vibrating members are multidimensional. (MLH)

Describes acoustical systems utlilized for mapping ocean floors. (SL)

Compared vocal features of deception that can be measured by acoustic equipment with vocal features of deception that can be measured perceptually by human coders. The study attempted to determine the degree of correspondence, if any, that exists between these methods. Results indicated moderate correlations between some acoustic and perceptual…

Presents an activity in which students design, construct, and test "super ears" to investigate sound and hearing. Students work in groups of three and explore how the outer ear funnels sound waves to the inner ear and how human hearing compares to that of other animals. (NB)

Introduces a lesson plan on astronomy and scientific research. Explains how astronomers conduct research and the detection methods they use. Provides demonstrations and ideas for students to build a giant model of the solar system. (YDS)

Presents activities to motivate students to appreciate sound in which different aspects of sound are introduced and different components of sound are discussed. Includes Internet resources. (KHR)

Discussion of classroom amplification systems to improve the performance of students with hearing loss or learning disabilities addresses the auditory challenges of inclusive classrooms, changing the classroom environment to reduce noise, types of amplification systems, and what teachers observe about amplification. (Contains references.) (DB)

The electroacoustic performance of 18 direct-input and two inductive-coupling hearing aids was compared when operating with two different frequency modulation (FM) systems. The most significant differences occurred in full-on gain, equivalent-input noise, and frequency response, as opposed to high frequency average saturation sound pressure level…

In the absence of a comprehensive theory of the spoken language, the exploration of dynamic phonotactics--of actual running speech--can contribute to the understanding of oral language properties. Information based on spoken language data may also have fundamental implications for second-language learning. (24 references) (Author/VWL)

The neuronal model shown to code sound-source azimuth in the barn owl by H. Wagner et al. in 1987 is used as the basis for a speculative brain-based human model, which can establish contrastive phonetic categories to solve the problem of perception "non-invariance." (SLD)

Describes a method for producing beat frequencies by carrying a vibrating tuning fork quickly toward a wall or chalkboard. A mathematical explanation is provided. (MVL)
