Effect of Sound Source Location and Spatial Hearing on the Vestibulo-Ocular Reflex (VOR)
… for extra- vestibular sensory factors such as hearing. Previous research has shown that the use of an auditory stimulus can have a significant effect on functional measures of balance, and many have contributed effects to be the result of spatial hearing. However, no studies have directly …

Neural correlates and mechanisms of sound localization in everyday reverberant settings
… for results from human psychophysical studies of spatial hearing in reverberant environments. This thesis marks fundamental progress towards elucidating the neural basis for spatial hearing in everyday settings. Overall, our results suggest that the information contained in the rate responses of …

Analysis of early auditory evoked potentials elicited by stimuli with directional information
… thesis is to elucidate a neural correlate of spatial hearing in humans. Auditory brain stem responses (ABRs) and binaural difference potentials (BDs) to stimuli with interaural differences in time (ITD) and level (ILD) are measured and analyzed. In chap. 2 the advantage of using information …

Space in electroacoustic music: composition, performance and perception of musical space
… choices and decision making with regard to spatial composition and performance is taken into consideration. The structure for the investigation is based on a model of musical space comprising three basic levels: 1) spatial properties of individual sounds in terms of intrinsic space, …

Models of binaural hearing for sound lateralisation and localisation
The current study suggests two models of binaural hearing, which aim to make predictions for inside- and outside-head localisation of a single sound source in the horizontal plane. Both models consider free-field ITDs and ILDs as the memory of sound localisation to which the target interaural …

Spectral spatiality in the acousmatic listening context
Sounds are often experienced as being spatially higher or lower in congruence with their frequency ‘height’ (i.e. pitch register). The term ‘spectral spatiality’ refers to this impression of spatial height and vertical depth as evoked by the perceived occupancy of evolving sound-shapes …

Modeling and Evaluating Human Sound Localization in the Natural Environment
… greatly advanced our understanding of binaural hearing but leaves us some ways from a complete understanding. In particular, it has been difficult to assess human sound localization in ways that align with humans experience on an everyday basis. This thesis aims to more closely align research …

Sensor(y) Landscapes : technologies for new perceptual sensibilities
… approach, my culminating work uses non-occluding spatial audio to create situated perceptions of data. I developed a bone-conduction headphone device, called HearThere, that renders a live soundscape from distributed microphones and sensors, fully merged with the user's natural hearing. HearThere …

Cognitive and Auditory Factors Underlying Auditory Spatial Attention in Younger and Older Adults
… the auditory and cognitive aspects of auditory spatial attention in conditions in which the location of the target was uncertain. In all experiments, word identification was measured for target sentences presented with two competitor sentences. On each trial, the three sentences were presented …

A Numerical Elastic Model for Deforming Bat Pinnae
In bats, the directivity patterns for reception are shaped by the surface geometry of the pinnae. Since many bat species are capable of large ear deformations, these beampatterns can be time-variant. To investigate this time-variance using numerical methods, a digital model that is capable of …

The creation of a binaural spatialization tool
… this thesis is, as the title suggests, binaural spatialization. Binaural technology and, especially, the binaural recording technique are not particu-larly recent. Nevertheless, the interest in this technology has lately become substantial due to the increase in the calculation power of personal …
