AES Technical Committee

Perception and Subjective Evaluation of Audio Signals

Chair:    Thomas Sporer      Send Email

The committee works to ensure that the members of the AES are kept up to date on the latest advances and practices in psychoacoustics, the evaluation of sound field recording, coding and reproduction systems, and psychometrics. This includes all aspects of listening tests and modelling of perception in computers.

Many quality assessment tests in the past focused on comparison with an explicitly given reference. In AR and VR applications in general there is no reference and new methods have to be found.

Due to the fact that the products created by audio engineers are target to human receivers and not to measurement systems, listening tests are the most important tools.

Areas of Concentration

  1. Psychoacoustics
  2. Evaluation of Sound Field Recording and Reproduction Systems
  3. Psychometrics
  4. Perceptual Quality Assessment
  5. Attributes and Dimension of Audio Quality
  6. Perceptual Measurement Schemes
  7. Assessment of Immersive Audio

Current Areas Of Work

  • Perceptual evaluation of spatial sound fields
  • Multi-dimensional testing and statistics (everything beyond just basic audio quality)
  • Head phone testing
  • Speech intelligibility

Future/Expected Activities

  • Perception of vibrations
  • Low frequency perception (architecture, musical instruments, reproduction)
  • CD with auditory examples of artifacts produced by modern audio codecs, esp. also concerning spatial artifacts (extension of "Audio Codecs - what to listen for" originally produced by TC-CAS)

Hot Topics

  • Evaluation of AR and VR systems
  • Testing without reference
  • Perceptual attributes for immersive audio
