Audiovisual spatial congruence, and applications to 3D sound and stereoscopic video
While 3D cinema is becoming increasingly established, little effort has focused on the general problem of producing a 3D sound scene spatially coherent with the visual content of a stereoscopic-3D (s-3D) movie. The perceptual relevance of such spatial audiovisual coherence is of significant …

Quantification of the performance of 3D sound field reconstruction algorithms using high-density loudspeaker arrays and 3rd order sound field microphone measurements
… measures can be taken. The recording of the sound field, the spatialization and the development of the loudspeaker arrays are some of the greatest challenges. In this thesis, these challenges for improving immersive audio will be explored. First, there will be a short introduction about 3D …

Scalable immersive audio for virtual environments
This thesis discusses the history of game sound and how it developed to become increasingly more immersive and realistic by accounting for the spatial aspects of sound. It then compares several 3D sound technologies before continuing on to present a custom spatial sound system that uses the highly …

Sparse separation of sources in 3D soundscapes
… applicable to extracting sources from within 3D soundscapes is presented. The algorithm is based on constructing a binary mask based on directional information. The validity of filtering using binary masked based on the ω-disjoint assumption is examined for several typical scenarios. Results …

Towards Understanding and Developing Virtual Environments to Increase Accessibilities for People with Visual Impairments
… navigate themselves with different types of 3D auditory feedback in the same VE; 2) if users could recognize the distance and direction of a virtual sound source in the virtual environment (VE) effectively; 3) if users could recognize the positions and distinguish the moving directions of 3D …

An Evaluation of Laboratory and Test Road Environments and Electric Vehicle Warning Sounds and Systems
… rapidly every year. Due to the decreased sound produced by these vehicles at low speeds, there is significant concern that pedestrians and bicyclists will be at increased risk of vehicle collisions. This is particularly true for those with vision impairment who cannot rely on visual cues …

Visually adaptive virtual sound imaging using loudspeakers
… open up new possibilities for three dimensional (3D) sound reproduction. The problem is to update the audio signal processing scheme for a moving listener, so that the listener perceives only the intended virtual sound image. The performance of the audio signal processing scheme is limited by the …

Forward sound propagation around seamounts : application of acoustic models to the Kermit-Roosevelt and Elvis seamounts
… understanding of the complicated phenomena of sound propagation around the seamounts. In addition, the experimental data could be used to validate current 2D and 3D theoretical models and develop new models to properly realize the sound propagation with such complicated phenomena. In this …

Characterization of the head-related transfer function using chirp and maximum length sequence excitation signals
… to compensate for unpredictable delay added in sound-acquisition software that lacks the capability of synchronized record/playback. The HRTF measurements obtained with an external probe microphone are compared with those obtained with the standard in-ear microphones that the KEMAR is equipped …
