Considers silence and the dimensions of sound. (Editor/RK)

Discusses important concepts regarding children's need for specialized acoustical standards in classrooms: (1) all children need good acoustics to understand familiar words and to learn new information; (2) children who have hearing loss, those learning in a second language, and those with auditory or attention problems need even more favorable…

Explains the physical principles of the tuning fork which has a common use in teaching laboratories. Includes information on its vibration, frequency of vibration, elasticity, and reasons for having two prongs. (YDS)

This article describes science activities which introduce students to the mechanics of sound while encouraging class musicians to share their expertise. A reproducible activity sheet is included. (IAH)

Ten normally hearing and 10 age-matched subjects with moderate-to-severe hearing impairments (ages 6-9) were recorded producing a protocol of 18 basic syllables. The syllables were analyzed for total duration, voice-onset time of the initial consonant, fundamental frequency at midpoint of vowel, and formant frequencies at midpoint of vowel.…

Describes the major types of acoustic analysis available for the study of speech, identifies equipment and other components needed for a modern speech-analysis laboratory, and lists possible measurements for various aspects of phonation, articulation, and resonance, as they might be seen in neurologically disordered speech. (Author/DB)

Often, the sound arriving at the ears is a mixture from many different sources, but only 1 is of interest. To assist with selection, the auditory system structures the incoming input into streams, each of which ideally corresponds to a single source. Some authors have argued that this process of streaming is automatic and invariant, but recent…

This study examined whether pitch patterns of prelinguistic vocalizations could discriminate between social vocalizations, uttered apparently with the intention to communicate, and "private" speech, related to solitary activities as an expression of "thinking". Four healthy ten month old English-speaking infants (2 boys and 2 girls) were…

This paper analyzes prosodic variables in a corpus of eighteen oral presentations made by students of Technical English, all of whom were native speakers of Swedish. The focus is on the extent to which speakers were able to use their voices in a lively manner, and the hypothesis tested is that speakers who had high pitch variation as they spoke…

As school performance under NCLB becomes increasingly important, districts can not afford to have barriers to learning. That is where wireless sound-field amplification systems come into play. Wireless sound-field amplification systems come in two types: radio frequency (RF) and infrared (IR). RF systems are based on FCC-approved FM and UHF bands…

A previous study has shown that Swedish children with language impairment have prosodic problems at different levels of language. The aim of this study is to investigate prosodic problems at the discourse level in two of the children to see whether they are related to pragmatic problems. Prosodic and pragmatic abilities were assessed by perceptual…

This study investigated the intelligibility of Chinese graduate students to their Indian, Chinese, Korean, and American peers. Specifically, the researcher sought to determine the teaching priorities for English for Academic Purposes in the US, where listeners have a wide variety of native languages. Research on Second Language Acquisition…

This popular guide offers a wealth of innovative, research-based strategies for making K-12 classrooms the best learning environments they can be. Easy-to-implement best practices are presented for establishing a classroom management plan, organizing procedures and materials, building a respectful community, fostering peer collaboration, and…

This study concerns the diffraction of sound around flexible partitions used in teaching spaces. It includes a comprehensive study of the acoustical conditions in several school buildings in India, Malaysia, Singapore, and Sri Lanka. The noise reduction properties of some typical partitions the minimum height of the partition between two teaching…
