Soundfield representation, reconstruction and perception
This thesis covers the area of soundfield representation, reconstruction and perception. The complexity and information content of a soundfield presents many mathematical and engineering challenges for accurate reconstruction. After an in-depth review of the field of mathematical soundfield …

Soundfield simulation : the prediction and validation of acoustical behavior with compute models
In the past, acoustical consultants could only try to convince the client/architect that with calculations and geometrical plots they could create an acoustically superb space. Now, by modeling the significant acoustical parameters of a design, we can preview a proposed acoustical solution and it …

Spatial Audio for Bat Biosonar
… of echoes received by a bat. A spatial audio/soundfield microphone array is introduced to measure sounds in the sonar frequency range (20-80 kHz) of the big brown bat (Eptesicus fuscus). The custom-built ultrasonic tetrahedral soundfield microphone consists of four capacitive microphones that …

Capturing spatial audio from arbitrary microphone arrays for binaural reproduction
… that minimize the reconstruction error of the soundfield captured at the array relative to the head related transfer function is described. Our techniques are compared with the current state of the art in spatial audio, Ambisonic recording and reproduction. Additionally, case studies of several …

Private audio delivery in reverberant spaces
We study the problem of delivering private audio to multiple users in a reverberant room. New methods are proposed which work with specially designed noise signals and make constructive use of reverberation. First, traditional sound zones problem formulation is introduced. In this formulation, a …
