    Summary
    This summary is machine-generated.

    This study explores how the human hearing system uses sound cues from two ears to determine sound location. It reviews physical measurements and psychoacoustical effects involved in spatial hearing.

    Area of Science:

    • Auditory Neuroscience
    • Psychoacoustics
    • Acoustics

    Background:

    • The human auditory system processes complex sound information to perceive spatial characteristics of sound fields.
    • Binaural hearing, utilizing two ears, is crucial for localizing sound sources and understanding auditory scenes.
    • External ear transfer functions encode spatial information into sound signals reaching the eardrum.

    Purpose of the Study:

    • To review key issues in the formation of auditory event positions and extents using binaural hearing.
    • To examine the physical aspects of sound localization, including external ear transfer functions.
    • To outline psychoacoustical mechanisms involved in the auditory system's decoding of spatial sound information.

    Main Methods:

    • Measurement and analysis of external ear transfer functions.

    Related Experiment Videos

  • Review of psychoacoustical effects and mechanisms in auditory spatial perception.
  • Description of a conceptual model for binaural interaction.

    • Main Results:

    • External ear transfer functions are critical for encoding spatial sound information.
    • The hearing system decodes spatial cues by analyzing both interaural and monaural signals.
    • Psychoacoustical effects and mechanisms play a significant role in auditory spatial perception.

    Conclusions:

    • Understanding binaural interaction is essential for explaining how we perceive sound locations.
    • The interplay between physical acoustics and psychoacoustics underlies our ability to localize sound.
    • This review provides a framework for further research into the mechanisms of spatial hearing.
