Reports on an acoustical investigation of syntactic stress in alaryngeal speech. Measurements were made of fundamental frequency, relative intensity, vowel duration, and intersyllable duration. Findings suggest that stress contrasts in alaryngeal speech are based on a complex of acoustic cues which are influenced by linguistic structure.…

Provides a biography of Bell's life with particular emphasis on his scientific contributions. (CP)

This paper explores the issues associated with poor acoustics within schools. Additionally, it suggests remedies for existing buildings and those under renovation, as well as concerns for new construction. The paper discusses the effects of unwanted noise on students in terms of physiological, motivational, and cognitive influences. Issues are…

This publication provides essays on the acoustical design of music education facilities and reproductions of posters describing 50 projects presented at the 117th Meeting of the Acoustical Society of American held in Syracuse, New York in May 1989. Essays are as follows: "Introduction to the Design Process" (Richard Talaske); "The…

Presents theoretical and experimental observations made with a musical toy called Hummer consisting of a corrugated flexible plastic tube about three-feet long and one-inch diam open at both ends. Included are descriptions of three new instruments: the Water Pipe, the Gas-Pipe Corrugahorn Bugle, and the Gas-Pipe Blues Corrugahorn. (CC)

Discusses the Doppler effect as it applies to different situations, such as a stationary source of sound with the observer moving, a stationary observer, and the sound source and observer both moving. Police radar, satellite surveillance radar, radar astronomy, and the Doppler navigator, are discussed as applications of Doppler shift. (JR)
