Purpose: In this study, the authors aimed to analyze longitudinal data from high-speed digital images in normative subjects using multi-line kymography. Method: Vocally healthy subjects were divided into young (9 men and 17 women; M[subscript age] = 27 years) and older groups (8 men and 12 women; M[subscript age] = 73 years). From high-speed…

Digital forms of sound manipulation are eroding traditional methods of sound development and transmission, causing a disjuncture in the ontology of music. Sound, the ambient phenomenon, is becoming disrupted and decentred by the struggles between long established controls, beliefs and desires as well as controls from within technologized contexts.…

A review of records was completed to determine whether children with auditory hypersensitivities have difficulty tolerating loud sounds due to auditory-system factors or some other factors not directly involving the auditory system. Records of 150 children identified as not meeting autism spectrum disorders (ASD) criteria and another 50 meeting…

Purpose: Children acquire /-ez/ syllabic plurals (e.g., buses) later than /-s, -z/ segmental plurals (e.g., cats,dogs). In this study, the authors explored whether increased syllable number or segmental factors best explains poorer performance with syllabic plurals. Method: An elicited imitation experiment was conducted with 14 two-year-olds…

Purpose: To determine what research evidence exists to support the use of voice measures in the clinical assessment of patients with voice disorders. Method: The American Speech-Language-Hearing Association (ASHA) National Center for Evidence-Based Practice in Communication Disorders staff searched 29 databases for peer-reviewed English-language…

Here is a way to show a sound wave travelling through air in real time. The method employs a set of low-cost microphone--LED units and demonstrates the movement of a pulse of sound as it lights up LEDs along a long (100-200 m) distance across a field. (Contains 4 figures.)

Purpose: Temporal interruption limits the perception of speech to isolated temporal glimpses. An analysis was conducted to determine the acoustic parameter that best predicts speech recognition from temporal fragments that preserve different types of speech information--namely, consonants and vowels. Method: Young listeners with normal hearing…

Western participants consistently match certain shapes with particular speech sounds, tastes, and flavours. Here we demonstrate that the "Bouba-Kiki effect", a well-known shape-sound symbolism effect commonly observed in Western participants, is also observable in the Himba of Northern Namibia, a remote population with little exposure to…

Noise is a fundamental hurdle that impedes the processing of information-bearing signals, specifically the extraction of salient information. Processing that is both optimal and efficient is desired; optimality ensures the extracted information has the highest fidelity allowed by the noise, while efficiency ensures limited resource usage. Optimal…

A systematic approach to retrieve individual parts in a monaural music recording with its score is introduced. We are interested in isolating the accompaniment part by removing the solo part from a recording of concerto music in which a solo instrument is accompanied by an orchestra. We require the music audio, the score, and optionally a sample…

Under controlled conditions, we assessed acoustically (long-term average spectra) and perceptually (singer survey, listener survey) six performances of an soprano, alto, tenor, and bass (SATB) choir ("N" = 27) as it sang the same musical excerpt on two portable riser units (standard riser step height, taller riser step height) with…

This study investigates the relationship between visual attention and reading time using a mobile electroencephalography device. The mobile electroencephalography device uses a single channel dry sensor, which easily measures participants' attention in the real-world reading environment. The results reveal that age significantly influences visual…

Discourses of achievement often overlook the interdependence of classroom contexts, students' identities, and academic performance. This narrative analysis explores how high-achieving students of color construct identities-in-practice in a diverse urban middle school. By documenting explicit moments in which students construct…

Building on Elliot and Silverman's (2015) embodied and enactive approach to musicing, I argue for an extended approach: namely, the idea that music can function as an environmental scaffolding supporting the development of various experiences and embodied practices that would otherwise remain inaccessible. I focus especially on the materiality of…

This column provides background science information for elementary teachers. When the author was young he used to think that the ideal design for a concert hall would contain walls that were composed of sound-absorbing material, like foam or egg cartons or such. He noticed, though, that this was not the case. Most concert halls contain curtains…
