This report is a summary of two studies. In the first, we compared examples of Irish fiddle performances with Western classical violin performances. Acoustical analyses showed that both classical examples produced average spectral centroids higher in frequency, higher harmonic to noise ratios, more use of vibrato, more disjunct intervals, and less…

This study was designed as a prospective, randomized controlled trial. A total of 90 preterm infants who underwent retinopathy of prematurity (ROP) examinations were categorized into three groups, a control group, a white noise group (WN), and a classical music group (CM), each comprising 30 preterm infants. The study data were obtained using an…

Purpose: University is an important time for learning; therefore, it is vital that the classroom acoustic environment is conducive for all students. The aim of this scoping review was to determine what is known from the literature about the effect of classroom acoustic conditions on university students' listening, learning, and well-being and…

The students' classroom well-being of college students has been widely concerned in online education researches. In order to implement effectively online education in colleges and universities, based on person-context interaction theory, this study investigates a theoretical model of the impact of teacher-student interaction, sound richness, sound…

Observing the bouncing of a marble on a table is a rather common experience. The tic-tac sound of the rigid ball, nevertheless, carries quite a pleasant surprise. In fact, by measuring the total time of bouncing [delta]t, the coefficient of restitution can be estimated. As is well known, in an inelastic collision the kinetic energy is not…

While augmented reality (AR) technology has shown the potential to facilitate students' hands-on activities, few studies have explored its effectiveness in acoustic topics. This paper introduces an AR-based application for learning about the Doppler effect and investigates its educational effectiveness on students' learning achievement, interest,…

In this study, we investigated primary school children's perspectives on their hearing and listening in classrooms with different acoustic quality levels. The sample included 213 children. The children completed a self-report questionnaire rating how well they could hear and listen in various situations in classrooms with two different acoustic…

Background: The voices virtual on-screen characters use has been shown to impact learning and perception outcomes. Recent replication research on these voices showed that synthetic voices were not a detriment if produced by a high-quality engine with clear articulation. The current manuscript examines previous accent research that utilized now…

Multimodal learning analytics (MMLA) research has shown the feasibility of building automated models of collaboration quality using artificial intelligence (AI) techniques (e.g., supervised machine learning (ML)), thus enabling the development of monitoring and guiding tools for computer-supported collaborative learning (CSCL). However, the…

Purpose: Pitch variations (tone productions) have been reported as a measure to differentiate Cantonese-speaking children with and without childhood apraxia of speech (CAS). This study aims to examine fundamental frequency (F0) changes within syllables and the effects of syllable structure, lexical status, and syllable positions on F0 in…

Background: In the modern music industry, AI music generators have gained particular importance. The use of AI greatly simplifies the creation of polyphony. In addition, it can increase student motivation and interest. Aims: This study focuses on the AI-assisted creation of polyphonic music. The purpose of this study is to determine how creating…

Classrooms are often noisy environments, which can result in unfavorable learning conditions for students. However, research has insufficiently addressed how noisy classrooms affect autistic students. This preliminary study examined differences in, and the impact of, background noise on reading performance for elementary-aged autistic and…

The determination of the speed of sound in air is a classical experiment, usually performed with a resonance tube apparatus. The measured value can be checked against Eq. (1), which describes the temperature dependence of the speed of sound in dry air. A modern implementation of this speed of sound investigation uses an Arduino Uno microcontroller…

Purpose: The Test for Rating Emotions in Speech (T-RES) has been developed in order to assess the processing of emotions in spoken language. In this tool, spoken sentences, which are composed of emotional content (anger, happiness, sadness, and neutral) in both semantics and prosody in different combinations, are rated by listeners. To date,…

Purpose: Secretion bubbling on the superior aspect of the velopharyngeal (VP) valve typically occurs with a small VP opening during production of oral pressure consonants. The use of high-speed nasopharyngoscopy has shown correlation between the bubbling frequency and the acoustics captured with the nasal microphone of the nasometer. The purpose…
