The objective of this study is to offer a view on the different environmental factors that affect health (sound, light, colour, temperature) in the design, planning and organization of school premises. To achieve this, the authors first outline the problems leading to unhealthy situations. They subsequently analyse all the building and planning…

The present study investigated the perception and production of English /w/ and /v/ by native speakers of Sinhala, German, and Dutch, with the aim of examining how their native language phonetic processing affected the acquisition of these phonemes. Subjects performed a battery of tests that assessed their identification accuracy for natural…

This guide describes the ways in which sounds are generated, travel, and affect the listener's hearing and well-being. Recommendations are given for controlling noise at the source and along its path of travel, and for protecting the listener. Remedies are given for noise commonly encountered in homes, work environments, schools, while traveling,…

The research reported in these papers covers a variety of communication problems. The first paper covers research on sound navigation by the blind and involves echo perception research and relevant aspects of underwater sound localization. The second paper describes a research program in acoustic phonetics and concerns such related issues as…

Recent work concerned with task performance under conditions of high arousal has emphasized the changes that appear to occur in the allocation of attention to different components of the task. (Editor)

Vowel quality in pretonic syllables seems to result both from the interaction of the four main parameters of stress within the syllable and from the relationship of these values to those of the tonic vowel. (Author/MSE)

Lightweight air supported fabric roofs over stadiums in Pontiac, Michigan, and at the University of Northern Iowa in Cedar Falls will be the largest air supported structures to date. (Author/EA)

Spectral compositions of voiced initial stops reveal that these consonants are longer in intensity than those in medial or final position. In final stops the vocal cords are more closed than they are in initial stops and oscillation is richer. (SC)

THE FORM OF A GENERATIVE SYSTEM FOR FUNDAMENTAL VOICE FREQUENCY IN MANDARIN CHINESE IS DISCUSSED, AND SEVERAL ASSUMPTIONS ARE MADE IN ORDER TO REDUCE THE PROBLEM TO A MANAGEABLE SIZE. DATA WAS GATHERED FROM TWO SPEAKERS BY HAVING THEM READ A PREPARED LIST WHICH CONTAINED ISOLATED WORDS, TWO-TUPLES, AND THREE-TUPLES IN ALL POSSIBLE COMBINATIONS OF…

Since 1965, Utah State University (USU) has been developing special programs for moderately and severely hard-of-hearing individuals as distinct from deaf persons. For the 1968-69 academic year, a pilot project was established for 16 students.This project of educational audiology was designed to explore the educational resources of USU, compare…

The fundamental frequencies (Fo) of infant cries were analyzed to determine if mean cry Fo differed as a function of the infant's sex or due to the stimulus evoking the cry. Results indicate no significant differences in either; however, males exhibited a tendency to have higher mean Fo. (Author/KM)

Spectrographic analyses were performed of utterances of three groups of children: four producing correct /w,r,l,j/ (ages three-five), four with developmental w/r and w/l substitutions (age four), and four with articulation impairments (ages six-seven). Findings supported the hypothesis that children's underlying forms are unique and represent…
