Individual Differences in Pitch Perception
… investigating individual differences in pitch perception. Experiment 1 identified otherwise normally hearing adult listeners who were relatively insensitive to the direction of small but detectable frequency changes between sequential pure tones. Following previous research, an important …

Enhancing voice pitch perception in cochlear implants
… restoring hearing and, to many users, speech perception. However, they suffer in more complex tasks such as pitch perception. In particular, poor voice pitch perception affects CI users’ ability to perceive information necessary for contextual cues in speech, such as emotion, speaker gender, …

The auditory fingerprint : multidimensional characterization of individual pitch perception in musicians
… in elementary hearing functions, sound perception mode, musical instrument preference, performance style, as well as musical abilities such as absolute- and relative pitch perception or auditory imagery (audiation). However, relevant literature in the field regarding perceptual and …

Pitch perception and harmonic resolvability in normal-hearing and hearing-impaired listeners
… often impaired in their ability to perceive the pitch associated with the fundamental frequency (FO) of complex harmonic sounds. Four studies investigated the relationship between FO discrimination performance and the ability to resolve individual harmonic frequencies of a complex, testing the …

An examination of pitch-matching techniques utilized by middle school choral directors to improve pitch accuracy for uncertain singers
… the most effective techniques for advancing pitch accuracy among uncertain singers in middle school choral programs. Results show that middle school female singers are significantly more accurate in pitch-matching than middle school male singers, and grade level proves to influence pitch …

Examing the evidence for a pitch centre in human auditory cortex: a multi method approach
… (EEG) methods to evaluate the evidence for a pitch centre within auditory cortex according to the four pitch criteria: 1) pitch selectivity, 2) pitch constancy, 3) covariation with pitch salience, and 4) accounting for confounding factors, that were described in an article by Hall and Plack …

DESIGNING SERIOUS GAMES FOR HABILITATION AND LEARNING - FROM EAR TRAINING TO SINGING
… at promoting music appreciation by enhancing pitch perception and production abilities of CI users. The iterative design process that involved 16 cochlear implant users is documented, and a controlled comparison study (involving another 12 cochlear implant users) between SECCIMA and a baseline …

The Augmented Geometrically Spaced Transform : applications of the single channel frequency estimator
… AGST is a good front-end model for computational pitch perception. For example, it can be used to solve an important problem in auditory perception, the case of the missing fundamental. The entire thesis is framed in the context of building artificially intelligent music systems, including …

Pitch representations in the auditory nerve : two concurrent complex tones
Pitch differences between concurrent sounds are important cues used in auditory scene analysis and also play a major role in music perception. To investigate the neural codes underlying these perceptual abilities, we recorded from single fibers in the cat auditory nerve in response to two …

The cognitive organisation of musical pitch
… the idea that the rationales for the forms of pitch organisation employed within tonal music which have been adopted by music theorists have strongly affected those theorists` conceptions of music, and that it is of critical importance to music theory to investigate the potential origination of …

Current steering and electrode spanning with partial tripolar stimulation mode in cochlear implants
… such as speech recognition in noise and music perception, possibly due to the small number of implanted electrodes and the large current spread of electric stimulation. Although current spread may be reduced using partial tripolar (pTP) stimulation mode, the number of electrodes may not be …

Task-optimized models of human hearing link perception and neural coding
… of which features of neural coding underlie perception. This thesis develops computational models for explicitly linking specific features of peripheral auditory processing and perception. In a series of three studies, we optimized deep artificial neural network models to perform real-world …

Pitch Estimation of Musical Signals
Can a computer algorithm assess musical pitch with results analogous to those of a trained human musician? This thesis attempts to answer that question by demonstration. It starts by examining the nature of pitch, and human spectrotemporal perception of music. In pitch vibrato, the frequency varies …

The effect of directed attention score study procedures on music majors' error detection in three-part instrumental music
… instrumental music on music majors’ detection of pitch and rhythm errors. Directed attention participants studied one voice prior to studying the entire score through either visual or aural methods. Visual group participants (n = 20) studied the voice of directed attention (VDA), which was color …

Non-native perception, production, and lexical processing of tone
… learner’s first language, namely the function of pitch for lexical distinctions (‘L1 tonal status’) and the shapes of native tonal and intonational contrasts (‘tone type’), as well as extralinguistic factors, namely musical experience, working memory, and pitch perception aptitude. In doing so, I …

The Effect of Timbre and Vibrato on Vocal Pitch Matching Accuracy
… has shown that singers are better able to match pitch when the target stimulus has a timbre close to their own voice. This study seeks to answer the following questions: 1. Do classically trained female singers more accurately match pitch when the target stimulus is more similar to their own …

Effects of Earplug Material, Insertion Depth, and Measurement Technique on Hearing Occlusion Effect
… bodily- generated sounds and result in distorted perception of one's own voice, many people report annoyance with hearing aids and hearing protectors that produce occlusion effects. Previous research has studied the effects of ear device insertion depth and influence of the location of the bone …

The Effect of Linguistic Experience on the Perception of Pitch Contour
Studies conducted in the area of tone perception suggest that experience with tonal features such as pitch height, direction, duration, and contour in the L1 of the listener affect the perception of such features. This study consists of a categorical perception experiment to investigate whether …
