Integrating Ocean Acoustics and Signal Processing

The combination of ocean acoustical physics and signal processing has been the central theme of our research over the last twenty years. In particular, the thrust of our research has been in matched field processing, waveguide invariant physics, time reversal acoustics, acoustic communications, sensitivity kernel analysis, and correlation based noised processing. Common to all these areas is th...

Inverse filtering of room acoustics - Acoustics, Speech and Signal Processing [see also IEEE Transactions on Signal Processing], IEEE Tr

A novel method is proposed for realizing exact inverse filtering of acoustic impulse responses in a room. This method is based on the principle called the multiple-inputloutput inverse theorem (MINT). Because a room impulse response generally has nonminimum phases, it has been impossible to realize exact inverse filtering of room acoustics using previously reported methods. However, the exact i...

Virtual Acoustics and 3-d Sound in Multimedia Signal Processing

In this work, aspects in real-time modeling and synthesis of three-dimensional sound in the context of digital audio, multimedia, and virtual environments are studied. The concept of virtual acoustics is discussed, which includes models for sound sources, room acoustics, and spatial hearing. Real-time virtual acoustics modeling is carried out using a real-time parametric room impulse response r...
