CV Ville Pulkki

Associate Professor, Department of Signal Processing and Acoustics

School of Electrical Engineering (ELEC) Aalto University, Finland

In his PhD studies (1995-2001) Ville Pulkki was working on amplitude panning (link) techniques for multi-channel loudspeaker set-ups. He developed then vector base amplitude panning (VBAP), which is taken into use nowadays.  In his postdoc time, Ville Pulkki extended the work by developing a method for capturing and reproducing a sound field based on the knowledge of spatial hearing:  Directional Audio Coding.
In 2014 Ville Pulkki received the Samuel L.Warner memorial award Society of Motion Picture and Television Engineers (SMPTE). The award is given of outstanding contributions in the field of spatial sound reproduction and multi-channel

In Oct 2017, he received the Silver Medal Award (formerly the Emile Berliner Award) by the Audio Engineering Society which is given in recognition of outstanding development or achievement in the field of audio engineering.

More about Ville Pulkki

Currently, Ville Pulkki, Associate Professor from the Department of Signal Processing and Acoustics at Aalto University, Helsinki, is a Visiting Professor at Hearing Systems. Ville Pulkki will be staying until end of June.

Ville Pulkki’s main focus is on spatial sound generation and perception by amplitude panning techniques. This is particularly interesting and relevant also for the Hearing Systems group where alternative techniques have been used to recreate sound scenes in the laboratory. The idea of Ville Pulkki’s visit is to discuss and develop novel ways of sound field reproduction to study sound processing and perception in controlled complex acoustic environments.

"Ville Pulkki has worked on functional modeling of auditory brain mechanism. So we have various areas where we can interact and learn from each other."

Why is it interesting for you to come and visit this specific group?

“Hearing Systems is one of the biggest groups that is active in this research area and I have also discussions with the Acoustic Technology Group. We did acoustical measurements with laser-induced pressure pulses three years ago where I had some contributions and we published it together,” Ville Pulkki says and continues:

My playground is spatial sound
“This place might be twice as big as our lab in Helsinki. In Denmark there is so much of acoustics going on. The Hearing Systems Group has a lot of expertise in auditory perception, technical audiology and applied hearing research. But there is a mutual interest in collaboration between our research groups because some of the studies in the Hearing Systems Group are within the area of spatial audio,” he says and adds:
“My playground is the spatial sound and working with microphones,” he explains with a smile.
For those who are interested in finding out how spatial recordings can actually sound depending on the recordings, there is a chance to experience his work in the audio visual immersion lab.

Head of Hearing systems Torsten Dau is very pleased to have Ville Pulkki as a guest professor in the group:
“Ville Pulkki is known worldwide for his achievements within spatial audio reproduction techniques and his research on the perception of spatial sound in complex audiovisual environments. Furthermore, he has also worked on functional modeling of auditory brain mechanism. So we have various areas where we can interact and learn from each other,“ Torsten Dau concludes.

At Aalto University, Ville Pulkki leads the spatial sound research group. The work of the spatial sound group concentrates on methods to capture and reproduce sound in a way that humans will perceive the spatial characteristics in a desired manner, for instance, spatial audio. Some researchers in the group are working on time-frequency-domain parametric spatial audio reproduction methods, others on acoustical measurements of head-related acoustics and room acoustics, and other researchers are working on psychophysical perception of spatial sound and corresponding functional signal-driven models of human auditory pathway in the brains.
