| Abstract: |
The technologies and psychoacoustics of spatial sound have been studied at
Dept Signal Processing and Acoustics in Helsinki University of Technology
for more than 15 years. The current streams of research are covered in the
presentation. The technology studies concern the reproduction and coding of
spatial sound, the acoustics of external ear and ear canal, and augmented
reality audio. The studies on psychoacoustics concern the perception of
spatial distribution of wide sound sources, and computational modeling of
binaural perception of spatial sound. Some multichannel demonstrations will
be given on Directional Audio Coding application as the audio engine for
virtual worlds. |
| Bio: |
Dr Ville Pulkki has M.Sc on technical physics, and D.Sc on Acoustics from
Helsinki University of Technology. He has also studied music and audio
engineering at Sibelius Academy, Dept Musical Education. In his doctorate
thesis (2001), he developed Vector Base Amplitude Panning technique for
virtual source positioning over multichannel loudspeaker setups, and studied
it with listening tests and computational auditory modeling. Later he has
developed Directional Audio Coding for capturing, coding and reproduction of
spatial sound, and have been working on new types of functional models of
auditory brain mechanisms for binaural hearing. |
