Prosodic Comparisons Between Speech And Music For Different Emotions, Reagan Brothers

Honors Projects

This study compares the prosodic acoustic characteristics between different emotional expressions in speech and clarinet playing and evaluates the similarities in prosody between these two domains. The prosodic features analyzed include pitch, loudness, and duration, which are the psychoacoustic terms referring to fundamental frequency [f_o], intensity, and rate of time. The American folksong “I’ve Been Working on the Railroad” was both spoken and performed with three emotions: neutral, sad, and happy. The first comparison was how each prosodic characteristic compared across the three different emotions within each domain, and then prosody was compared across the two domains …

Too Loud To Ignore: Knowledge, Attitudes, And Practices Regarding Hearing Protection In Student Musicians And Ensemble Directors, Lucile Donald, Ashley G. Flagge

Ashley Flagge Publications

Musicians are at an elevated risk for noise-induced hearing loss (NIHL) due to repeated exposure to sound levels exceeding occupational safety guidelines. Although many strides have been made in educating music students on the potential dangers of noise exposure and the mitigating effects of hearing protection devices, the current attitudes on this topic among high school and college-level student musicians remain largely unknown. An electronic survey was administered to high school (n = 195) and university (n = 161)-level band students and ensemble directors (n = 15) regarding knowledge of noise/music-induced hearing loss (MIHL), personal practices with HPDs, and types …

Localization Of Music In Perceived Motion In Cochlear Implant Users, Madeleine Beyer

Dissertations, Theses, and Capstone Projects

Spatial perception contributes to music perception and enjoyment, yet it remains understudied in cochlear implant (CI) users. Spatial effects in music are often achieved through panning, a tool which redistributes an audio signal level between or among several outputs, creating a perceived sound localization. CI users typically perform worse than normal hearing (NH) listeners on tasks of horizontal localization and music perception when manipulating the actual location of the sound. However, despite the common use of panning in daily use and consumption of music, no previous studies were conducted to examine how panning impacts the listening experience for CI users. …

Music And Word Learning In Children Diagnosed With Developmental Language Disorder, Rebekah G. Sweeney

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Purpose: This study investigates whether incorporating music into vocabulary interventions improves rate of learning and retention of words in children with developmental language disorder (DLD). Emerging literature continues to show the plentiful benefits of music as a tool for intervention in many settings, including the world of speech pathology (Levitin, 2024). However, it is also evident that there is a connection between struggling with language, and struggling with musical elements, such as rhythm and pitch perception, particularly in children with DLD (Boorom et al., 2022; Kreidler et al., 2023). This study seeks to tease out if music is an effective …

A Comparison Of Vestibular Function In Young Adult Musicians And Non-Musician Peers, Alexandria W. Greene, Ashley G. Flagge, Nicholas S. Stanley

Ashley Flagge Publications

Purpose: The majority of college-level musicians exceed the daily recommended noise dose level during instrumental practices and performances, although less than one-third report wearing hearing protection while playing their instruments. Although the hazardous effects of music on the auditory system have been established, even in young adult musicians still early in their musical careers, the effects of music on the vestibular system are still unclear. The purpose of the present study was to examine vestibular/balance differences between young adult musicians and non-musicians to determine the effects of music exposure on the vestibular system.

Method: Young adult participants aged 18-27 years …

Articulatory Activity Of The Tongue, Jaw, And Lips During The Second Passaggio Transition Of The Soprano Voice, Richard C. Lissemore

Dissertations, Theses, and Capstone Projects

This dissertation describes three experiments designed to explore the acoustic and articulatory activity of a perceptible change in the soprano voice known as the secondo passaggio, or second transition, which typically occurs for the [ɑ] vowel between D♮5 (587 Hz) and F♮5 (698 Hz). Acoustically, the transition involves a shift in resonance strategy from second resonance tracking of the second harmonic (f_R2/2f_o) to first resonance tracking of the fundamental frequency (f_R1/f_o). To quantify the acoustics of the transition, we employed the measure L₁-L₂, the …

Though these therapies may significantly alter one's appearance and overall well-being, they are also capable of causing notable declines …

Trumpet Directivity From A Rotating Semicircular Array, Samuel D. Bellows, Joseph E. Avila, Timothy W. Leishman

Directivity

The directivity function of a played musical instrument describes the angular dependence of its acoustic radiation and diffraction about the instrument, musician, and musician’s chair. Directivity influences sound in rehearsal, performance, and recording environments and signals in audio systems. Because high-resolution, spherically comprehensive measurements of played musical instruments have been unavailable in the past, the authors have undertaken research to produce and share such data for studies of musical instruments, simulations of acoustical environments, optimizations of microphone placements, and other applications. The authors acquired the data from repeated chromatic scales produced by a trumpet played at mezzo-forte in an anechoic …

The Effect Of Different Warm-Up Durations On Subjective And Objective Measures Of Singing In Choral Singers Over The Age Of 55, Jeremy A. Chesman

Graduate Theses/Dissertations

Choral singing is a popular activity in the United States. Choral singers are often encouraged to warm up vocally before they sing. Considering voice conditions, like presbyphonia, that can develop shortly after retirement, more research about vocal warm-ups is needed for those over the age of 55. This study assesses the effects of various durations of vocal warm-ups on subjective and objective measures of the singing voice using a within-groups design with randomized condition order. Nine participants performed vocal warm-ups for 0, 5, 10, and 15 minutes. A song sample was then recorded and sent to two expert raters who …

Effect Of Consistent Singing On Maintenance Of Speech Intelligibility Following Lsvt®: A Retrospective Longitudinal Case Study, Rachel Ricca Beck

Graduate Theses and Dissertations

Parkinson’s Disease is a common neurodegenerative disease affecting one’s ability to hone and refine volitional movement. Many with Parkinson’s report significant effects on voice and communication. Speech-language pathologists have long targeted the achievement of increased vocal volume through intensive voice therapy, with the most common program being Lee Silverman Voice Treatment® (LSVT®) (Ramig et al., 1994). While LSVT® is the most prominent type of voice therapy for individuals with Parkinson’s, other researchers have begun investigating therapeutic singing because of the similar functions it employs (e.g., increased breath support, utilization of entire vocal range).

The current project is a retrospective, longitudinal …

Amplification Vs The Natural Ear: A Test On The Effectiveness Of The Natural Ear On Adults Ability To Match Pitch In Song, Celeste Orozco

A new technology, the Natural Ear provides altered auditory feedback to the user while singing. It is hypothesized that this feedback may aid in the userâ??s ability to match pitch.

Purpose: The purpose of this study is to compare the effects of the Natural Ear to amplification and no amplification conditions on pitch matching accuracy in song.

Study Design: This study used a complex counterbalance within-subjects design.

Methods: 50 adults from the El Paso Metropolitan …

The Effectiveness Of The Natural Ear On Adults Ability To Accurately Match Pitch, Kendra Nicole Rosales

Open Access Theses & Dissertations

Background: Many theories, such as oral motor, perceptual, and sensorimotor deficits, have been posited to explain inaccurate pitch matching abilities. The current study identifies with the sensorimotor deficit theory and found it to be the most plausible explanation for inaccurate singing abilities. The Natural Ear (NE) program was designed to process voice productions in real-time and filter out the discordant harmonics, allowing a person to hear only their F0.

Purpose: The purpose of this study was to examine the effectiveness of the Natural Ear program in increasing pitch matching accuracy in singers.

Methods: A total of 50 participants were included …

Similarities And Difference In The Neural Processing Of Speech And Song In Religious Music, Brett Pielstick

Undergraduate Honors Theses

An fMRI study was performed to see the differences in the neurological processing between spoken and sung language in religious music. Students at Brigham Young University, who are members of the Church of Jesus Christ of Latter-day Saints, were exposed to alternating blocks of spoken and sung lyrics of religious and non-religious songs. There was no significant activation when contrasting speech and song, but there was significant activation in the right middle temporal gyrus and the posterior cingulate gyrus when listening to spoken and sung religious lyrics, suggesting an emotional reaction to religious stimuli. Contrasting spoken stimuli for both religious …

Singing Portuguese Nasal Vowels: Practical Strategies For Managing Nasality In Brazilian Art Songs, André Campelo

Theses and Dissertations--Music

The articulation of Portuguese nasalized vowels poses some articulatory problems accompanied by negative acoustic effects for the performance of Brazilian art songs. The main objective was to find strategies that permit the singer to conciliate an idiomatic pronunciation of these vowels with a well-balanced resonance, a desirable quality in classical singing. In order to devise these strategies, the author examined sources dealing with nasalized vowels from varied perspectives: acoustic properties of vowel nasalization, phonetic and phonological aspects ofBrazilian Portuguese (BP), historical views on nasality in singing, and recent vocal pedagogy research. In addition to the overall loss of sonority, the …

Fundamental Frequency Characteristics Of Modal And Vocal Fry Registers, Heidi Brubaker, Jason Albertson Whitfield Ph.D., Jane Schoonmaker Rodgers D.M.A.

Honors Projects

This study examined the distribution of fundamental frequencies in the connected speech of 14 healthy young adults. Acoustic analysis of fundamental frequency was performed on previously collected speech samples of a phonetically balanced reading passage. For the first three sentences of the reading passage, fundamental frequency contours were extracted using PRAAT, a speech analysis software package. The accuracy of these contours were visually verified and manually corrected when needed. The distribution of the fundamental frequency histories for each sample were then analyzed using Gaussian Mixture Model analyses in MATLAB. For most speakers, four statistical modes were identified in the data …

A Call For Hearing Loss Prevention Programs In College Music Education Programs, Jason Taurins

Honors Theses

Music educators, ensemble conductors, and students who participate in musical ensembles are exposed to sound pressure levels which exceed the criteria for NIOSH. As such, this population should be enrolled in hearing loss prevention programs. Ensemble directors (many music educators fall into this category) have a direct role in influencing the sound pressure levels produced in rehearsals. Music educators have a role in influencing the knowledge, skills, attitudes, and behaviors of their students. Because of the health risks of noise exposure, and the role music educators (and ensemble directors in general) have in influencing their students, hearing loss prevention should …

A Preliminary Study Of The Articulatory And Acoustic Features Of Forward And Backward Tone Placement In Singing, Krista Wyllys

Masters Theses

A variety of terms exist for describing tone quality in singing, and voice scientists, voice therapists, teachers of singing, and students of singing use different terms to describe the same sound. One aspect of tone quality is tone placement. Teachers of singing often rely on imagery and imitation to elicit correct tone placement from students of singing. More concrete data about what produces forward and backward tone placement could supplement singing teachers’ current practice of using imagery and imitation to elicit a desirable tone quality. This study examined forward and backward tone placement to determine the articulatory gestures and acoustic …

Structural Processing Of Language Components: Detection And Comprehension, Samantha Rose Crow

Wayne State University Theses

Although music and language share many perceptually functional characteristics, research endeavors are still focusing on the underlying neural circuitry. Past research has indicated a distinction of hemispheric lateralization between music and language processing. Recently, efforts have shifted to the notion of an initial general shared pathway in the brain with auditory stimuli differentiated in later processing to specialized regions. Therefore, both linguistic and musical components have been examined in numerous experiments to discern the possible influence of music and language components on auditory perception and comprehension, including their potential interaction. However, the effects of sentential prosody on early language structural …

Treatment For Children With High Functioning Autism: A Comparison Of Social Stories To Musically Adapted Social Stories, Veronica M. Torres
