This book is designed to be a quick and easy resource for anyone teaching physics for the first time. Written after extensive research, this book is filled with reliable labs, demos and activities that work well in the classroom. Also included are lesson plans, diagrams, and teacher notes for every activity. The book is not the end--it is just a…

While exploring the development of Communication and Learning Aids in all venues, particularly the effect of music on learning, several different tracks were followed. The therapeutic use of music is for relaxation and stress reduction, which apparently helps the body to access and discharge deeply locked-in material. The Mozart Effect track which…

Students in a fourth-grade class participated in a series of dynamic sound learning centers followed by a dramatic capstone event--an exploration of the amazing Trashcan Whoosh Waves. It's a notoriously difficult subject to teach, but this hands-on, exploratory approach ignited student interest in sound, promoted language acquisition, and built…

Regardless of the extremely subtle acoustic changes that are perceptible within almost all perception research studies, it is the total overall effect that generally occupies each individual listener. A long line of research indicates that many subtle "music changes" are often not perceived accurately and are actually mistakenly identified.…

A study employed computational and experimental methods to address a number of issues related to the representation and structural organization of spoken words in the mental lexicon. Using a computerized lexicon consisting of phonetic transcriptions of 20,000 words, "similarity neighborhoods" for each of the transcriptions were computed.…

Describes demonstrations which can be performed with a synthesizer and oscilloscope combination. (Author/CP)

Describes the principal modules of analog electronic music synthesizers and discusses some ways that a synthesizer has been used in demonstrations, in psychophysical experiments, and in an undergraduate laboratory course in the physics of music and acoustics. Considers the synthesis of both steady and transitory auditory phenomena. (Author/MLH)

Discusses the ratio of energy dissipated as sound to the mechanical output of devices. Considers noise levels, ranges vs. peaks, noise indexes, and health hazards. Indicates some problems vs. solutions in the technology of noise control. (GH)

A study of speakers of a range of English dialects was conducted to investigate some influences on the pattern of phonetic final devoicing of phonologically voiced fricatives and affricates. With the help of spectrographically examined tape-recorded speech derived from sociolinguistic interviews of the subjects, the study examined seven English…

This experiment investigated whether suppressing correlated vowel phonemes of consonants by pairing each consonant with a redundant vowel /a/ would have the same effect on recall in two input modes - auditory and articulatory. (Editor/RK)

Advocates increased use of language laboratory facilities. Suggestions for improving the acoustic and pedagogical quality of recorded materials are made. (PMP)

SINCE THE 19TH CENTURY, KYMOGRAPHIC RECORDING OF TOTAL AIR FLOW OUT OF THE MOUTH HAS BEEN USED TO DIAGNOSE THE VARYING DURATIONS AND DEGREES OF CONSTRICTIONS OF THE VOCAL TRACT DURING SPEECH. THE PRESENT PROJECT ATTEMPTS TO INTRODUCE A SECOND DIMENSION TO RECORDINGS OF AIR FLOW OUT OF THE MOUTH--NAMELY, CROSS-SECTIONAL AREA OF FLOW--ON THE…

THOSE IN CHARGE OF PLANNING AND COSTING HAVE FOUND FAVOR WITH CARPET AS A PRACTICAL, ACOUSTICAL, ENVIRONMENTAL CONTROL MATERIAL. CARPET FITS WELL INTO IMPROVED AND DESIRABLE DESIGN IN TODAY'S COLLEGE BUILDINGS. CARPET PLAYS THE ROLES OF SEVERAL MATERIALS, PERFORMING SIMULTANEOUSLY, ACOUSTICAL, THERMAL, AESTHETIC, SAFETY, AND POSITIVE PSYCHOLOGICAL…
