Sound and Space

 

The theme "Sound & Space", launched in 2004, aims to host emerging research at LIMSI in the area of ​​the audible acoustics, outside of speech. These research directions are classified into three categories: spatial hearing, room acoustics, and virtual reality.

In the field of Spatial Audition, our efforts are linked strongly to the Head-Related Transfer Function (HRTF). The audio virtual reality applications are strongly based on the use of HRTFs to render 3D audio over headsets. The studies in spatial hearing focus on the following concepts:

  • The relationship to the specific morphology of the individual
  • Inter- and intra-subject variability
  • Estimation and prediction methods
  • HRTF simulation using the finite element method (BEM)
  • Plasticity of the auditory system adapted for non-indivuels HRTFs
  • Mutlimodal interactions in spatial perception

Listening in isolation is rare. We are typically situted in complex environements with reflecting surfaces and architectural details. To compliment spatial hearing studies, we are intertessed in spatial aspects of sound fields. In the field of Acoustics Room, studies have focused on the following concepts:KU80 Athénée

  • Real-time simulation tools
  • Coupled volumes
  • Spatial Cognition
  • Acoustic archeology, acoustics past places

During the last decade, virtual reality and augmented reality have taken an ever more important place in our daily life. Through the media, simulation tools, and assistive devices, audio-visual renderings systems have significantly evolved to meet diverse needs. However, the spatial dimension of audio modality is still relatively little used and may prove beneficial for large audiovisual applications. The purpose of our activities in virtual reality and augmented and audio interfaces is to study what can be the impact of 3D sound for these different applications.
