Measurements of the fundamental frequencies of Danish vowels showed a positive correlation with tongue height. The fundamental frequency differences between high and low vowels were greatest in long vowels in stressed position, while short vowels in unstressed position differed to a much lesser degree.

An experiment tests conjectures that right ear advantage (REA) has an auditory origin in competition or interference between acoustically similar stimuli and that feature-sharing effect (FSE) has its origin in assignment of features of phonetically similar stimuli. No effect on the REA for acoustic similarity, and a clear effect of acoustic…

Describes a few apparatuses and demonstrations for teaching physics under the headings: demonstrating resonance of the inner ear, constructing a potential well-hill for overhead projectors, rubber tube vacuum pump, improvement on the simple homemade motor, air track to demonstrate sailing into the wind, and center of gravity and stability. (GA)

Reviews the earthquake phenomenon and its possible relation to ionospheric disturbances. Discusses the basic physical principles involved and the methods upon which instrumentation is being developed for possible use in a tsunami disaster warning system. (GA)

Years of research and experience have helped us develop the guidelines that may yet salvage the acoustically dim record of open plan schools. (Author/MLF)

Reviews theories, developments, and advances in the field of acoustic microscopy. (SL)

Several traditional phonetic theories are explained and discussed. It is asserted that recent advances in knowledge of speech production and speech perception show that these theories are descriptively inadequate and that physiologic principles may instead structure phonetic feature theories. (Author/RM)

The selective tuning of feature detectors sensitive to the acoustic information relevant to the assignment of distinctive phonetic feature values was investigated with a contingent adaptation paradigm. (Author/RM)

A description of an electromyographic investigation carried out on the speech of deaf speakers. The research attempted to answer questions concerning articulation and phonetic patterns in the speech of deaf adults. Results indicated that the deaf speakers extended the duration of speech segments and exhibited difficulty coordinating articulation…

Discusses practical considerations for planning and designing microcomputer laboratories so that equipment can be easily installed, protected, and accessed. (MLF)

Claims that in metrical prose, rhythm can convey sense or express and underline what a writer is saying, and sound can be exploited to add a strong aural element that provides pleasure to the ears over and above the pleasure given by the sense of story. (SRT)

Discusses the acoustics of bells by examining what determines the quality of a bell, the frequency it emits, and the note perceived by the listener. The analysis concentrates on a ship's bell but also considers several handbells. Laboratory bench set up for studying bells and nodal lines of bells are illustrated. (BC)

Discussed is a Doppler shift laboratory experiment for an introductory college physics course. Ultrasonic transducers and a digital phase detector circuit "black box" are used to overcome room noise and "standing waves" and to produce an observable frequency shift. (SL)

Describes an elementary one-semester course in the physics of sound and light with an emphasis on applications in art, music, photography, and theater. (MLH)

This study investigated the following questions: (1) "What are the perceptions that elementary school principals have concerning the influence of interior design elements such as floor and wall coverings, lighting, flexibility, acoustics, color, texture, patterns, cleanliness, and maintenance on student achievement, teacher retention, and student…
