Noise is sound of any kind that is undesirable and unwanted as part of the environment under consideration. It is one of the types of pollution that have great impact on our health and wellbeing. The occurrence of noise in our environment is increasing daily because of growing population and industrialization. Noise pollution have great…

Purpose: This study investigated the ecological validity of conventional voice assessments by comparing the self-perceived voice quality and acoustic characteristics of voice production during these assessments to those in a simulated environment with varying distracting conditions and noise levels. Method: Forty-two university professors (26…

While our perceptual experience seems to unfold continuously over time, episodic memory preserves distinct events for storage and recollection. Previous work shows that stability in encoding context serves to temporally bind individual items into sequential composite events. This phenomenon has been almost exclusively studied using visual and…

Purpose: The ability to understand speech under adverse listening conditions is highly variable across listeners. Despite this, studies have found that listeners with normal hearing display consistency in their ability to perceive speech across different types of degraded speech, suggesting that, for at least these listeners, global skills may be…

The formation of chemical patterns is in general difficult to control due to the random diffusive motions of the reacting chemical species in solution. In this paper, we present a new method using audible sound to control the formation of chemical patterns obtained in blue bottle experiments. The waves generated on the surface of the solution by…

Many publications describe use of ultrasound imaging in teaching of clinical courses, primarily integrated with clinical applications. More recently there have been increasing numbers of papers describing ultrasound as a tool primarily for teaching basic anatomy and physiology concepts rather than clinical applications. Of these, many have…

One of the difficulties in teaching Turkish, which is a phonetically rich language, to foreigners, is that similar sounds are often confused with each other. Since even a single punctuation mark is crucial for writing and reading Turkish letters (i-i, o-ö, u-ü, c-ç, g-g, s-s, etc.), students who use the Arabic alphabet have great difficulty…

Purpose: The study aims to explore factors that influence students' academic performance in the context of physical ergonomics and assess the mediating effect of motivation between lighting, noise, temperature, chair design and students' performance from the student's perspective. Design/methodology/approach: The research was categorised as a…

The purpose of this study was to assess the effects of three choral configurations on a soprano section's sound. The first configuration resembled a choir section without an assigned standing position, the second configuration grouped singers by timbre, and the third used acoustic-compatibility placement. Three conductors configured a university…

A tension between freedom and constraint is characteristic of improvisation practice and pedagogy, presenting challenges for teachers/workshop leaders. To create musical focus in ensemble improvisation, some sounds are encouraged, whilst others are edited out, ignored or marginalised. This article investigates improvised sounds as central or…

Teaching alternating currents, ac or sound waves, is incomplete without an introduction to the oscilloscope. An oscilloscope is a tool that graphically displays electrical signals and shows their time dependence. However, due to the pandemic, triggered by the SARS-CoV-2 virus, many students do not have the opportunity to master the use of an…

Purpose: Dysphonic voices typically present multiple voice quality dimensions. This study investigated potential interactions between perceived breathiness and roughness and their contributions to overall dysphonia severity. Method: Synthetic stimuli based on four talkers were created to systematically map out potential interactions. For each…

Purpose: Sleep-based memory consolidation has been shown to facilitate perceptual learning of atypical speech input including nonnative speech sounds, accented speech, and synthetic speech. The current research examined the role of sleep-based memory consolidation on perceptual learning for noise-vocoded speech, including maintenance of learning…

We propose an experiment in which the sound of a drumroll is recorded and analysed according to a simple mechanical model in which the inelastic restitution coefficient of the collision between the stick and drum surface, as well as the ongoing kinematics of the drumstick, are considered. The agreement shows that this model is well suited for…

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…
