Virtual Acoustics

The Virtual Acoustics Research Group is concentrating on room acoustics – how it could be measured, simulated, and auralized as well as how humans perceive different rooms, in particular the team is world-know on the research of concert halls.

The aim of the Virtual Acoustics group is to get an encompassing understanding how rooms modify sound that we hear. To pursue this goal, the group is investigating auralization, spatial sound capturing and reproduction, binaural technology, and novel objective and subjective evaluation methods, as well as physically-based room acoustics modeling methods. Particularly, the interest has been in concert halls, in which the group has developed new measurement techniques, analysis methods for spatial impulse responses, and sensory evaluation methods to understand the perceptual differences between concert halls. 

The current research topics are:

  • 3D-sound capturing and reproduction (both with microphone arrays and within room acoustics simulations)
  • sound in virtual/augmented reality applications
  • perception of speech in noise and reverberation
  • acoustics of chamber music halls
  • acoustics of cinemas and studios
  • novel bio-based absorption materials

The Virtual Acoustics Research Group belongs to the Aalto Acoustics Lab. The research group is led by Professor Tapio Lokki, AES Fellow.
