This paper reports on a literature review conducted in the UK for the Design Council and CfBT (Higgins et al., 2005) which looked at the evidence of the impact of environments on learning in schools. We have reviewed the available evidence regarding different facets of the physical environment and provided an analysis based on different areas of…

The study investigated the effects of music with high arousal potential and negative affect (HA), music with low arousal potential and positive affect (LA), and everyday noise, on the cognitive task performance of introverts and extraverts. Forty participants completed five cognitive tasks: immediate recall, free recall, numerical and delayed…

The physics of sound is often studied in introductory physics class experiments involving a tube of resonating air. In typical setups, pistons control the length of a cylindrical space or a microphone is moved within a tube. While these activities are useful and can be made very quantitative, they don't directly demonstrate the sounds that are…

This paper investigates the nature of the substitutions used for the dental fricatives (/theta/ and /eth/) by Dutch learners of English as a second language. By means of an OT analysis, the underlying reasons for the difficulties encountered with these sounds are brought to light. The present data reveal that phonetics (or acoustics) rather than…

This study determined the effects of sound-field amplification (SFA) on the speed with which students with attention deficit hyperactivity disorder (ADHD) followed teacher directions. A multiple baseline design was used with 3 elementary-aged students with ADHD to assess the effects of SFA across 4 types of directions: (a) task demand (e.g., get…

The aim of the present study was to investigate the interplay between personality factors and metaphorical schemas. The "Big Five" personality factors of 20 patients after lung transplantation were examined with the NEO-FFI. Patients were questioned about their social network, and self- and body-image. The interviews were assessed with metaphor…

Acoustic properties of the cries of 14 infants were evaluated at both 2 and 4 weeks of age when the infants were lying in a supine position and when they were sitting upright in a car seat. In the upright position, infants' breathing was more rapid and showed less individual variability. The fundamental frequency of their cries increased in the…

A challenging task in physical studies of the upper ocean using underwater sound is the interpretation of high-resolution acoustic images. This paper covers a number of basic concepts necessary for undergraduate and postgraduate students to identify the most distinctive features of the images, providing a link with the acoustic signatures of…

Purpose: The contribution of audible high-frequency information to speech-understanding performance in listeners with varying degrees of high-frequency sensorineural hearing loss was examined. Method: Thirty-six elderly hearing-impaired (EHI) and 24 young normal-hearing (YNH) listeners were tested in quiet (+20 dB speech-to-noise ratio [SNR]) and…

The purpose of this study is to provide new perspectives on correlates of phonetic transcription agreement. Our research focuses on phonetic transcription and coding of infant vocalizations. The findings are presumed to be broadly applicable to other difficult cases of transcription, such as found in severe disorders of speech, which similarly…

Purpose: When understanding speech in complex listening situations, older adults with hearing loss face the double challenge of cochlear hearing loss and deficits of the aging auditory system. Wide-dynamic range compression (WDRC) is used in hearing aids as remediation for the loss of audibility associated with hearing loss. WDRC processing has…

Purpose: This study investigated the acoustic characteristics of pediatric cochlear implant (CI) recipients' imitative production of rising speech intonation, in relation to the perceptual judgments by listeners with normal hearing (NH). Method: Recordings of a yes-no interrogative utterance imitated by 24 prelingually deafened children with a CI…

Language is generally viewed as conveying information through symbols whose form is arbitrarily related to their meaning. This arbitrary relation is often assumed to also characterize the mental representations underlying language comprehension. We explore the idea that visuo-spatial information can be analogically conveyed through acoustic…

College students' pronunciations of initial "c" and "g" were examined in English words and nonwords, both monosyllables and polysyllables. Pronunciations were influenced by adjacent context--whether the following letter was "e" or "i"--and by long-distance context--whether the item contained a suffix or spelling pattern characteristic of Latinate…

The purpose of this online study was to create a ranking of essential core competencies and technologies required by AET (audio engineering technology) programs 10 years in the future. The study was designed to facilitate curriculum development and improvement in the rapidly expanding number of small to medium sized audio engineering technology…
