This article discusses the incorporation of architectural principles into redesigning a classroom at York University (Ontario) for a mix of university students and professors/lecturers who are culturally deaf, oral deaf, hard of hearing, late deafened, and hearing. Special design features include lighting and color, noise control, furniture, and…

Presents an alternative to the use of a radar to determine how fast an individual can serve a tennis ball. Equipped with a tape recorder and a Macintosh computer, students determine the velocity of a tennis ball by analyzing the sounds and echoes heard on the court. (ZWH)

Presents experiments to measure the velocity of sound through metals and other amorphous materials. Describes the equipment used to make the measurements and the possibility of interfacing with a microcomputer. (MDH)

Discusses ways in which marine biology can be integrated into the physics classroom. Topics suggested for incorporation include the harmonic motion of ocean waves, ocean currents, the interaction of visible light with ocean water, pressure, light absorption, and sound transfer in water. (MDH)

This article reviews some relevant events in the development of acoustical standards for classrooms, describes classroom challenges to providing clear acoustical signals to children in classrooms, and outlines amplification solutions to some of those classroom challenges. Solutions include personal amplification devices and use of signal-to-noise…

This article discusses the lack of an acoustic standard in classrooms and an effort by a broad-based coalition of engineers, audiologists, parents, architects, and educators to develop a standard for acoustics that would then be referenced in the Americans with Disabilities Act. The benefits to all children are emphasized. (Contains six…

This closing article on a clinical forum exploring negative effects of classroom noise on learning discusses the need to make structural changes to classrooms to provide a high-quality acoustical environment for learning. The efforts of the Classroom Acoustics Working Group to develop acoustic standards for classrooms is highlighted. (Contains one…

This draft standard developed by the Classroom Acoustics Working Group provides acoustical performance criteria and accompanying design guidelines intended to ensure good speech communication among students and teachers in learning spaces. To ensure the noise limits are not exceeded, adequate sound isolation between classrooms and adjacent spaces…

Provides basic information relating to the different aspects of facilities planning for interactive distance education, including site selection, acoustics, lighting, environmental considerations, and electrical power. The importance of facilities planning during the developmental stages of an interactive distance education project is emphasized.…

Interface and instructional design guides almost completely ignore sound, and research suggests many promising instructional uses remain largely unexplored. Examines information processing and communication theoretical foundations for sound's systematic use in the instructional communication system and proposes a framework for a program of…

In this pilot study we sought to determine the reliability and validity of collecting speech and voice acoustical data via telephone transmission for possible future use in large clinical trials. Simultaneous recordings of each participant's speech and voice were made at the point of participation, the local recording (LR), and over a telephone…

This study examined Australian English (AE) and Thai-English bilingual (TE) speakers' ability to perceive word-final stops in their native and non-native languages. In the perception experiment, the TE listeners were able to discriminate stop contrasts differing only in place of articulation (/p/-/t/, /p/-/k/, /t/-/k/) in both English and Thai…

Purpose: This study examined whether the intraoral transducers used in electromagnetic articulography (EMA) interfere with speech and whether there is an added risk of interference when EMA systems are used to study individuals with aphasia and apraxia. Method: Ten adult talkers (5 individuals with aphasia/apraxia, 5 controls) produced 12 American…

The present paper comprises an overview of techniques using ultrasound in speech (re)habilitation. Ultrasound treatment techniques have been developed for English lingual stops, vowels, sibilants, and liquids. These techniques come from a series of small "n" studies with adolescents and adults with severe hearing impairment, residual…

Converging evidence supports the hypothesis that the most common subtype of childhood speech sound disorder (SSD) of currently unknown origin is genetically transmitted. We report the first findings toward a set of diagnostic markers to differentiate this proposed etiological subtype (provisionally termed "speech delay-genetic") from other…
