Auditory distance perception is less accurate than visual perception in open fields. Walking responses confirmed that sound-based distance estimates were systematically biased and less precise than vision-based estimates.

Area of Science:

  • Auditory perception
  • Spatial cognition
  • Human psychophysics

Background:

  • Auditory distance perception is crucial for navigation and interaction.
  • Previous research often conducted in controlled, enclosed spaces.
  • Naturalistic listening conditions present unique challenges for spatial auditory processing.

Purpose of the Study:

  • To investigate auditory distance perception in a large, open field under naturalistic conditions.
  • To compare auditory and visual distance perception using motoric responses.
  • To assess the accuracy and consistency of sound-based distance judgments.

Main Methods:

  • Three experiments were conducted in a large open field.
  • Targets were presented at egocentric distances ranging from 3 to 16 meters.

  • Participants used verbal reports or walking responses (direct or indirect paths) to indicate perceived target locations.

    • Main Results:

    • Walking and verbal responses for auditory targets were largely consistent but less precise than for visual targets.
    • Motoric responses yielded reliable estimates of perceived locations and distances.
    • Auditory targets were perceived with significant systematic errors, showing reduced distance variation and a tendency for underestimation.

    Conclusions:

    • Auditory distance perception in open fields is prone to systematic errors compared to visual perception.
    • Motoric responses provide a robust measure for assessing spatial perception accuracy.
    • The findings highlight limitations in auditory spatial localization under naturalistic conditions.
