An inservice training model for successful implementation of FM (Frequency Modulation) transmission systems for hearing impaired students must take into account its purpose and functions, mechanics, and management. (CD)

The new fine arts complex at Memphis State University (Tennessee) has extensive south-facing windows and massive Trombe walls, composed of concrete blocks that absorb heat and release it slowly, that together provide about 20 percent of the building's heat. Part of the masonry was also designed to absorb sound. (Author/MLF)

Surveys 50 years of acoustical studies by discussing selected topics including the ear, nonlinear representations, underwater sound, acoustical diagnostics, absorption, electrolytes, phonons, magnetic interaction, and superfluidity and the five sounds. (JN)

The study investigated the rate of oral air flow for plosive consonants produced by 10 normal hearing adult males, 10 hearing impaired adult males who demonstrated intelligible speech, and 10 hearing impaired adult males with semi-intelligible speech. (Author)

Augments Michael Studdert-Kennedy's state-of-the-art report on speech perception research (EJ 227 656) with comments on categorical perception of speech and nonspeech stimuli, speech perception in context, the role of prosody, and development/impairments of speech perception. Includes a summary of a discussion on speech perception research. (RL)

Presents a novel graphic representation for complex musical spectra, based on component intervals rather than component tones. Provides examples of this kind of plot in representing complex intervals and chords, discussing perceptual data; and carrying out various types of consonance analysis. (Author/CS)

This investigation compared the reading comprehension of 60 fourth-grade students in an open space school during periods of quiet and periods of naturally occurring background noise. Noise had no significant effect on accuracy or reading speed. (JMF)

Describes the following laboratory equipment: Biophysics modules to perform bioelectronic investigations of the human body; a large sine wave analog for large audience demonstrations; a resonance tube for measurement of speed of sound; and the snooperscope, a gadget to demonstrate infrared waves. (GA)

Under conditions of serial recall of auditorily presented lists of digits, recall of the last item has been shown to be adversely affected by the presence of a redundant item following the list. It is shown that the size of this effect, the suffix effect, is not influenced by the phonological complexity of the suffix. (Editor/RK)

Describes needed equipment and procedures for shattering a glass goblet with the amplified output of an audio oscillator. (MLH)

Describes experiments to address the properties of brass musical instruments that can be used to demonstrate sound in any level physics course. The experiments demonstrate in a quantitative fashion the effects of the mouthpiece and bell on the frequencies of sound waves and thus the musical pitches produced. (Author/NB)
