Examines listeners' use of acoustic properties in making personal attributions. In three experiments, subjects listened to recordings of male speakers answering two interview questions and rated the speakers on a variety of scales. (CM)

Applied to the recognition of words in noise, the theory of the perceptual identification of complex stimuli provides a quantitative account of the proportions in which correct and erroneous responses of different frequencies will occur. (Author)

Background information on the acoustics of the violin is given as a basis for student physics laboratory projects. References are suggested that can provide a basis for many experiments. (SA)

In order to investigate the articulatory dynamics of the tongue in the production of Swedish vowels, electromyographic (EMG) and X-ray microbeam studies were performed on a native Swedish subject. The EMG signals were used to obtain average indication of the muscle activity of the tongue as a function of time. (NCR)

Discusses the following: another version of Doppler beats; alternate proof of spin-1 sin-1/2 problems; some mechanisms related to Dirac's strings; Doppler redshift in oblique approach of source and observer; undergraduate experiment on noise thermometry; use of the time evolution operator; resolution of an entropy maximization controversy;…

Investigates and explains the phenomenon associated with Rubens flame-tube demonstration, specifically the persistance of flames at regular intervals along the tube for few minutes after the gas is turned off. (GA)

Describes demonstrations used by the nineteenth century physicists to determine if two bodies oscillating at the same acoustic frequency were in phase. (GA)

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)
