Sound Production in Two Loricariid Catfishes
<p>Many families of catfish produce sounds via pectoral spine stridulation and/or swim bladder compression using sonic muscles attached to the swim bladder. The sound production capabilities and characteristics in Loricariidae, the largest catfish family, have not been well examined. Sounds …

Modernising Cantonese opera through contemporary sound production design
… twenty years of experience as a professional sound designer, I was motivated by my love of Cantonese opera and my contemporary experience of its potential decline to undertake research into whether and how Cantonese opera in terms of production and management aspects could benefit from such …

Variation in sound production of the blue catfish, Ictalurus furcatus.
… via stridulation of the pectoral spine. These sounds can be made in air and water, and catfish can be preyed upon by both aerial and underwater predators. I characterized these putative distress calls by recording them in air and in the fish’s natural habitat. Sounds exhibited a wide variation …

Sound-production Related Cognitive Tasks for Onset Detection in Self-Paced Brain-Computer Interfaces
… Approach. To achieve this goal, various Sound-Production Related Cognitive Tasks (SPRCTs) were tested against idle state in offline and simulated-online experiments. An online experiment was then conducted that turned a messenger dialogue on when a new message arrived by executing the …

Bioacoustics and reproductive ecology of the damselfish Dascyllus albisella
While many fishes are known to produce sounds during courtship and aggression, the information contained in the sounds and their role in reproduction is not well understood. This thesis is an intensive investigation of the sounds produced by the damselfish Dascyllus albisella, the effect of the …

Structure and social significance of vocalization by Anolis grahami grahami (Sauria: Iguanidae)
… throughout the lizard suborder, only the sounds of geckos (Gekkonidae) have been closely studied. The purposes of this study were to describe the physical structure, social significance, and means of sound production by Anolis g. grahami, one of the 13 anoline species known to vocalize. …

Identification and Discrimination of Synthetic Sonorants by Children: The Influence of Disordered Articulation (Perception)
… discrimination of correct and incor- rect speech-sound production is based on the premise that there is a causal relation between speech perception and production. The purpose of this study was to determine whether there were differ- ences in the discrimination and identification abilities of …

The role of the saxophone embouchure in the production of the South African jazz sound : a study of nine jazz saxophone players
… known for having its own distinctive jazz music sound of which the saxophone is a significant feature. The saxophone has often been recognised world-wide as a symbolic jazz instrument and has also played an important role in South African jazz. As the embouchure of the saxophone is crucial to its …

Synthesis and perception of sounds from physical interactions reveals auditory intuitive physics
… scraping and rolling – create many of the sounds that we hear in the world around us. These sounds are generated via lawful physical dynamics. Anecdotally, humans possess some intuitive knowledge of the physical generative processes underlying sound production, but little is known about the …

Social Functioning Characteristics of a Young Adult with a History of Childhood Apraxia of Speech
… apraxia of speech (CAS) is a pediatric speech sound disorder (SSD) that results from a motor planning impairment for volitional speech movements. This underlying impairment causes pervasive errors in speech sound production and often leads to problems with intelligibility, thus inhibiting …

Toward a Semiotic Approach to Analyzing the Trombonist's Repertoire
… performance as well as physical similarities in sound production between brass instrumentalists and vocalists to apply current research in vocal gesture (Frith 1996, Burns 2001, Heidemann 2016) to the trombone. This theory extends into the realm of embodiment analysis (Larson 2012), and I explore …
