The paper reviews instrumental studies of "functional" misarticulations in children and reports an experiment involving three subject groups (N=7 in each group) of normally articulating adults, normally articulating children, and children who misarticulate the /s/ sound. (Author)

Outlines an approach for studying auditory levels in speech perception, focusing on the artificial speech understanding system that is most compatible with the experimental data obtained in speech perception research. (RL)

Facts about the specifications for carpets used in different areas in schools. (MLF)

Acoustical studies in seven different spaces in the four buildings of the WSU athletic complex measured noise levels and sound reverberation rates. The spaces measured were far noisier and more reverberant than quality educational spaces should be. Suggestions are made for improvement. (Author/MLF)

Describes the application of underwater acoustical technology by fishing industries. (SL)

Describes the use of a bell in the classroom to demonstrate the phenomena of beats and resonance. Explains properties of the bell, and its use in place of a demonstration with a spring is discussed. (PVD)

Presents an activity enabling students of grades four to nine to construct a "Buzzing Bee" model using simple materials. Provides students with the opportunity to explore the concepts of sound and the Doppler effect. (MKR)

Discusses the importance of acoustic standards in classroom design, presenting an interview with the Acoustical Society of America's (ASA's) standards manager which focuses on reasons for the new ASA standards, the standards document (which was written for K-12 classroom but applies to college classrooms), the need to avoid echo and be able to…

Research findings on articulatory and acoustic characteristics of infant noncry/nondistress vocalization are applied to the clinical assessment of infant noncry vocal activity. Discussed are differentiation and definitions of cry and noncry productions, stages of vocalization, a protocol for developmental vocal assessment, and interpretation of…

Presents activities that allow students in grades three to five to study sound by using children's tradebooks during exploration and experimentation. (JRH)

Presents a problem involving the double-slit interference pattern that relates to the real-world situation of guiding an aircraft to a safe landing. (JRH)

This study examined ambient noise levels, reverberation times, and noise/reverberation reduction treatments in 32 classrooms utilized for students with hearing impairment. None of the classrooms met recommended acoustical criteria for ambient noise levels, and only nine rooms complied with recommended standards for reverberation. (Author/DB)
