The udu is a traditional Nigerian percussion instrument that can be thought of as a Helmholtz resonator with two apertures. We use a simple two-particle mechanical analogue to study the behaviour of such a resonator and find that the model describes quite well the main features of udu acoustics.

This exploratory study describes the design and implementation of a sound-based intervention in the initial training of specialist music teachers at a Spanish university. It aimed to create spaces geared towards more creative and contemporary approaches to musical learning in order to gauge the perceptions of trainee teachers regarding this kind…

Across three separate investigations, this dissertation documents work examining the role of higher-order processes and cognitive effort during the top-down compensatory repair of degraded speech, specifically perceptual restoration. Perceptual restoration is a phenomenon where a listener can perceptually restore or repair speech…

The process of perceiving music involves the transference of environmental physics in the air to anatomical and physiological interpretations of resonance in the body and psychological perceptions in the brain. These processes and musical interpretations are the basis of physical and cognitive science, neurophysiology, psychoacoustics, and…

Purpose: Processing real-world sounds requires acoustic and higher-order semantic information. We tested the theory that individuals with autism spectrum disorder (ASD) show enhanced processing of acoustic features and impaired processing of semantic information. Methods: We used a change deafness task that required detection of speech and…

The developmental trajectory of audiovisual speech perception in Mandarin-speaking children remains understudied. This cross-sectional study in Mandarin-speaking 3- to 4-year-old, 5- to 6-year-old, 7- to 8-year-old children, and adults from Xiamen, China (n = 87, 44 males) investigated this issue using the McGurk paradigm with three levels of…

Word identification accuracy is modulated by many factors including linguistic characteristics of words (frequent vs. infrequent), listening environment (noisy vs. quiet), and listener-related differences (older vs. younger). Nearly, all studies investigating these factors use high-familiarity words and noise signals that are either energetic…

Within the broad, interdisciplinary field of adult education, affective aspects of experience and the roles they play in learning have, thus far, not been properly theorized or researched. This dissertation first explores how John Heron's whole person theory (WPT) conceptualizes feeling as an expansive affective capacity at the root of all human…

In this research, the effects of using Model-Based and Argumentation-Supported Model-Based Inquiry methods on 6th-grade middle school students' knowledge, scientific process skills, and motivation regarding the subject of sound and its properties were examined according to the current curriculum. A total of 77 students attending a state school…

By 12 months of age, infants exhibit behavioral sensitivity to sound symbolism (e.g. sound-shape correspondences) when they hear universally sound symbolic pseudowords (e.g. "bouba," "kiki"). Here, we investigated whether infant's sensitivity to sound-shape correspondences is affected when they hear language-specific sound…

Sound waves are one of the important topics studied in physics. However, students' graph representation is still low, leading to their low concept understanding of physics learning. Therefore, it is necessary to optimize the learning process to improve students' graph representation by providing a valid and reliable graph representation test…

Purpose: The purpose of this study was to examine the short- and longer-term effects (3-month follow-up) of a 1-month intensive straw phonation (SP) therapy on the voice quality and voice-related quality of life of female speech-language pathology (SLP) students with mild dysphonia. Method: Thirty-two female SLP students (mean age: 18.5 years,…

Purpose: We examined the effect of bite block insertion (BBI) on lingual movements and formant frequencies in corner vowel and diphthong production in a sentence context. Method: Twenty young adults produced the corner vowels (/u/, /[open back unrounded vowel]/, [ae]/, /i/) and the diphthong /[open back unrounded vowel][near-close near-front…

Our world is shaped profoundly by science and technology, which are strongly interrelated. The importance of integrating technology in science teaching is acknowledged by many international science-teaching standards in recent decades. The present study aims at examining how undergraduate students utilize what they have learnt about the physics of…

How do infants learn the sounds of their native language when there are many simultaneous sounds competing for their attention? Adults and children detect when speech sounds change in complex scenes better than when other sounds change. We examined whether infants have similar biases to detect when human speech changes better than nonspeech sounds…
