The occurrence of stuttering on stress-peak and unstressed syllables in connected speech was studied in 10 young adult stutterers. Results showed a significant coincidence of stutter events and syllabic stress peaks, particularly in polysyllabic words, though stuttering on the first three words of principal clauses appeared independent of syllabic…

Describes high-speed photographic methods used to demonstrate that the tip of a snapped towel does break the sound barrier. (ZWH)

Describes the use of chromatic musical instrument tuners to make frequency measurements of sound waves and as an exercise in the conversion of pitch to frequency. (ZWH)

A commercial noise dose meter was used to estimate the equivalent noise dose received through high-gain hearing aids worn in four classrooms in a school for deaf children. There were no significant differences among nominal saturation sound pressure level (SSPL) settings, and all SSPL settings produced very high equivalent noise doses. (Author/JDD)

Focuses on the relationship between loudness and intensity of sounds. (Author/PVD)

Focuses on the concepts of pitch and timbre of sounds. (PVD)

Evidence from Warren County, North Carolina suggests a three-variant distinction for negative forms (i.e., wasn't, weren't, and won't). Throughout the history of sociological investigation, two types of variant have been noted: a sociolinguistic and a linguistic. In Warren County, "won't" functions as both types. (Author/VWL)

Investigates conditions relating to the maximum useful-to-detrimental sound ratios present in classrooms and determining the optimum conditions for speech intelligibility. Reveals that speech intelligibility is more strongly influenced by ambient noise levels and that the optimal location for sound absorbing material is on a classroom's upper…

Focuses on three activities using the TI-92 graphing calculator that examine the relationship between the intensity of a light source and its distance from a measurement point, properties of a sound wave, and the relationship between the time elapsed and the temperature of a cooling substance. (ASK)

Presents an acoustical model and evidence from four experiments that children with visual impairments use the buildup of low-frequency sound along walls to guide locomotion. The model differs from the concept of echolocation by emphasizing sound that is ambient, rather than self-produced, and of low frequency. (Author/CR)

This article discusses the increasing number of students with hearing impairments in general education classrooms due to the higher incidence of students with hearing loss in general and changes in school placement decisions. The increasing noise in classrooms because of hands-on activities and the consequent effects on learning are explored.…

This introductory article to a clinical forum describes the following seven articles that discuss the problem of noisy classrooms and resulting reduction in learning, basic principles of noise and reverberation measurements in classrooms, solutions to the problem of poor classroom acoustics, and the development of a classroom acoustics standard.…

Examines the work of one teacher who taught the topic of sound to grade 8 students over a period of three weeks. Presents the findings of the study as five assertions using interpretive research methodology. Concludes with a discussion on the current reforms, which support that the integration of teaching with assessment leads to improvement of…

Suggests using the informal experiences students have through extracurricular activities such as music lessons to design a curriculum related to sound that encourages active student participation and learning. (DDR)

Explains how a toy called "Sound Bites" can be modified to demonstrate the transmission of sound waves. Students can hear music from the toy when they press it against any bone in their heads or shoulders. (WRM)
