This highly novel book provides an exploration of the role of silence in the school setting and interrogates the value of silence and quiet in contemporary educational practices, looking at pedagogies and classroom practice to guide this increasingly popular subdiscipline of the history of education. Arguably the first contribution written in…

Purpose: Listening is the gateway to learning in the mainstream classroom; however, classrooms are noisy environments, making listening challenging. Therefore, speech-in-noise tests that realistically incorporate the complexity of the classroom listening environment are needed. The aim of this article was to review the speech stimuli, noise…

Originally published as a special issue of Educational Studies, this volume demonstrates the ways in which sound considerations can significantly contribute to educational foundations. Regardless of their origin or interpretation, sounds are theoretically and practically foundational to educational experiences. As the means through which…

The treatment of Attention Deficit Hyperactivity Disorder is a matter of ongoing research and debate, with considerable data supporting both psychopharmacological and behavioral approaches. Researchers continue to search for new interventions to be used in conjunction with or in place of the more traditional approaches. These interventions run the…

Recent advances in data recording technology have given researchers new ways of collecting on-line and continuous data for analyzing input-output systems. For example, continuous response digital interfaces are increasingly used in psychophysics. The statistical problem related to these input-output systems reduces to linking time-varying…

The sustained vowel sounds of 14 noninstitutionalized 7- to 10-year-old children with Down's syndrome were analyzed acoustically for vowel formant amplitude levels. The subjects with Down's syndrome had formant amplitude intensity levels significantly lower than those of a similar group of speakers without Down's syndrome. (Author/DB)

Investigates the effects of acoustic similarity on memory span in 112 children four to 10 years of age. Acoustic similarity had progressively more effect on recall with increasing age. Implications for current theories of short-term memory and its development and for the use of acoustic similarity as an indicator of speech coding are discussed.…

Two experiments were conducted to assess the correlations of residue features with some perceptual properties of voice disorders. Results suggested that residue features may be useful in assessing the degree of vocal impairment, but use of residue features as correlates of voice quality requires further research. (Author/DB)

The study found no significant trends in the change of acoustical durations of stutter- and disfluency-free speech from readings in an adaptation series with four adapting, four nonadapting, and four nonstuttering subjects (all young adults). Findings suggest that adaptation of stuttering and other fluency-inducing conditions are a result of…

Five men repeated a phrase, beginning at total lung capacity and ending at residual volume. Analysis indicated that voice onset time (VOT) was longer at high lung volumes and shorter at low lung volumes. Lung volume should, therefore, be considered when using VOT as an index of laryngeal behavior in healthy and speech-disordered individuals.…

The paper describes the unexpected finding of evoked otoacoustic emissions from one ear of a subject with severe-to-profound bilateral sensorineural hearing loss. It is suggested that the subject may have a group of surviving outer hair cells in some regions of the left cochlea with corresponding inner hair cell or neural damage. (Author/DB)

Acoustic phonatory events were identified in 14 women diagnosed with adductor spasmodic dysphonia (ADSD), a focal laryngeal dystonia that disturbs phonatory function, and compared with those of 14 age-matched women with no vocal dysfunction. Findings indicated ADSD subjects produced more aberrant acoustic events than controls during tasks of…

This study evaluated speech intelligibility under noise conditions of varying peaks (10, 20, and 30 decibels) in frequency response, with 26 listeners with sensorineural impaired hearing who used hearing aids and 10 listeners with normal hearing. Results indicated that the peaks affected speech intelligibility more for listeners with impaired than…

The study examined the relationship between 28 segmental and suprasegmental acoustic parameters of speech production and measures of speech intelligibility for 40 severely to profoundly hearing-impaired persons (mean age 21 years). Findings support the tractability of employing selected acoustic variables for the estimation of speech…

This paper describes the Vocal Demodulator as a new device for analysis of vocal tremor. The Vocal Demodulator produces amplitude-demodulated and frequency-demodulated outputs and measures the frequency and level of low-frequency tremor components in sustained phonation. The paper describes quantification of the demodulation process, validation…
