In the present study, voice onset time (VOT) measurements were compared between a group of individuals with moderate Alzheimer's disease (AD) and a group of healthy age- and gender-matched peers. Participants read a list of consonant-vowel-consonant (CVC) words, which included the six stop consonants. The VOT measurements were made from…

This paper synopsizes a series of nine tutorials investigating how various chemical processes can be shown to have musical aspects. Both chemistry and music share a common language: mathematics. Interesting music can be created as chemical reactions--mediated by instrumentation and mathematics (e.g., spectrometry and discrete Fourier…

It may not seem like school is the best place to crank up the bass for glass-cracking extreme energy, but subwoofers just might make better teaching and learning tools than they do music makers. Faced with the fact that electricity is invisible, electrical technology students encounter significant challenges in the classroom when abstract concepts…

The purpose of this study was to specify variables which function significantly in the racial identification and speech quality rating of Negro and white speakers by Negro and white listeners. Ninety-one adults served as subjects for the speech task; 86 of these subjects, 43 Negro and 43 white, provided the listener responses. Subjects were chosen…

Purpose: To assess the Computerized Revised Token Test (CRTT) performance of individuals with normal hearing under several intensity conditions and under several spectral and temporal perturbation conditions. Method: Sixty normal-hearing listeners were randomly assigned to 1 of 3 groups. Group 1 provided performance-intensity information about…

Purpose: The purpose of this study was to compare the electroacoustic outputs of frequency-modulated (FM) systems coupled to hearing aids. Method: Electroacoustic performance of FM systems coupled to hearing aids was determined for 3 FM receivers: body-worn with neck loop, ear-level nonprogrammable, and ear-level programmable. Systems were…

The Science in Action series is designed to teach practical science concepts to special-needs students. It is intended to develop students' problem-solving skills by teaching them to observe, record, analyze, conclude, and predict. This document contains a student workbook which deals with basic principles of physical science. Six separate units…

A study reports a set of labelling criteria which have been developed to label prosodic events in clear, continuous speech, and proposes a scheme whereby this information can be transcribed in a machine readable format. A prosody in a syllabic domain which is synchronized with a phonemic segmentation was annotated. A procedural definition of…

A study investigated the nature of clear and dark sounds (resonance) in English, focusing on the features associated with the lateral consonant /l/. Subjects were three male undergraduate students and one male university faculty member, all native speakers of different English varieties. Each subject read aloud 27 short phrases or sentences. Using…

California has conducted on-site sound surveys of 36 different schools to determine the degree of noise, and thus disturbance, within the learning environment. This report provides the methodology and results of the survey, including descriptive charts and graphs illustrating typical desirable and undesirable sound levels. Results are presented…

Illustrates the phenomenon of the "difference tone" in music, using simple physics. Describes how this phenomenon can be demonstrated with a flute. (MLH)

The following three levels of intonation are described, and their relationship is discussed: 1) a concrete and atomistic level of the perceptually relevant pitch movements, 2) a concrete and global level of the audible pitch contours and the measurable fundamental frequency curves, and 3) an abstract and global level of intonation patterns.…

This article, directed toward classroom teachers, deals with music education as a special case of sound or sounds. Interdisciplinary activities aim to develop listening skills and musical discrimination. (TK)

Glass curtain walls at George Gund Hall, housing Harvard University's Graduate School of Design, and windowless classrooms at a junior high school next to Chicago's O'Hare Airport help to solve special problems while creating aesthetically pleasing buildings. (Author/MLF)

Discusses Helmut Richter's work on prosody. Looks at the problems of spoken language perception as belonging not only to phonetics and acoustics but also to psychology. (Text is in German.) (TL)
