RESEARCH AREAS

  • Applied Psychoacoustics: Unimodal and multimodal perception of sound and whole-body vibration
  • Relationships between judgments of loudness, sound characteristics and their contribution to the evaluation of sounds and appraisal
  • Psychoacoustic qualities of multi-tone sounds and their assessment
  • Acoustic quality of fan noise
  • Vehicle psychoacoustics (e.g. perception aircraft cabin noise)
