Technical Psychoacoustics

The Technical Psychoacoustics research group works at the intersection of technology and perception: we develop methods in virtual acoustics, spatial audio and machine listening, evaluate them perceptually, and apply them in hearing science.

The understanding of human perceptual mechanisms goes hand in hand with the development of human-centric virtual acoustics and spatial audio technologies. In our research, we aim to combine both technical and perceptual aspects into a more comprehensive view. We work on perceptually motivated methods for spatial audio reproduction and binaural rendering, develop and perform perceptual experiments to evaluate these technologies, and apply them in XR-based hearing science studies to investigate fundamental mechanisms of auditory and multimodal perception. In addition, we study machine listening and machine-learning-based audio processing for augmented hearing, considering both the technical performance of these systems and how listeners perceive their output. 

Due to the broad scope of our research area, we value interdisciplinary collaboration and work with experts from various disciplines to advance the technical fields of virtual acoustics, spatial audio and machine listening as well as the research fields of hearing science and hearing technology.

The current research topics are:

  • Virtual acoustics
  • Spatial audio
  • Binaural rendering with six degrees of freedom (6DoF)
  • Perceptual evaluation of spatial audio reproduction
  • XR-based hearing science
  • VR-based auditory processing assessment
  • Machine listening
  • Augmented hearing
     

The Technical Psychoacoustics research group belongs to the Aalto Acoustics Lab. The research group is led by Professor Johannes M. Arend. Information about the group's ongoing research projects can be found here.
