The contents of this book, which explains the techniques of sound engineering, sound design, and composition for the theatre, are compiled for the theatre student who knows very little about sound. Topics of chapters are acoustics, systems, equipment, sound for a theatrical production, recording and editing techniques, composing and creating sound…

There is reasonable agreement that hearing impairment is related to noise exposure. This hearing loss due to noise is considered a serious health injury, but there is still difficulty in delineating the importance of noise related to people's general non-auditory well-being and health. Beside hearing loss, noise inhibits satisfactory speech…

Fundamentals of sonar systems are presented in this book, prepared for both regular navy and naval reserve personnel who are seeking advancement in rating. An introductory description is first made of submarines and antisubmarine units. Determination of underwater targets is analyzed from the background of true and relative bearings, true and…

A model of phoneme identification is proposed which describes the process by which continuous acoustic featural information about the place of articulation and the voicing of speech sounds is integrated during phoneme identification. (AM)

This paper presents an inventory of the features that are necessary to describe vowel systems in the languages of the world. The relationship between the features and then articulatory and acoustic correlates is explored. (Author/NCR)

Investigated were the abilities of 98 educable mentally retarded adolescents to encode and retrieve words using semantic and acoustic cues in a free and cued recall task. Available from: Ablex Publishing Corporation, 355 Chestnut Street, Norwood, New Jersey 07648. (CL)

Describes several experiments which examined the basic claims of metrical phonology. The first two experiments examined the possible influences of stress clash in speech timing. The third and fourth experiments tested Hayes's (1984) analysis rule of quadrisyllabic meter; the fifth experiment included a basic test of the stress clash notion. (SED)

A descriptive model elaborated to account for the rhythmic organization of French and English is applied to the speech of French learners of English to identify the particular type of cross-linguistic influence operating therein. Evidence is presented for the existence of transitional rhythmic groups, perceived in the interlanguage vowel reduction…

Presented is a review of the physical acoustics of percussion instruments. Instruments included are the glockenspiel, marimba, xylophone, vibes, chimes, and triangles. (SL)

There is a considerable amount of research documenting the effects of noise on children. The effects are largely negative. Chronic exposure to noise has been shown to be harmful to children of various ages. It can have especially detrimental effects on younger children when language and discrimination skills are forming. Sometimes major noise…

Reports a study determining whether significant differences in formant frequency are apparent when chronological age is compared with a measure of physiological age for children during the first six years. (TO)

The Suvag Lingua is a machine used to facilitate better aural perception by working from a student's error in producing a particular sound and adapting the model which is to be imitated. (DD)
