The level-meter model accurately predicts interaural level difference (ILD) thresholds for noise, showing human sound localization is robust to stimulus details. Minor adjustments suggest a loudness-meter model improves accuracy for certain noise conditions.

Area of Science:

  • Acoustics
  • Psychoacoustics
  • Auditory Neuroscience

Background:

  • The interaural level difference (ILD) is crucial for sound localization.
  • Defining ILD for noise is challenging due to level fluctuations.
  • Existing models lack a clear interpretation for noise stimuli.

Purpose of the Study:

  • To propose and test the "level-meter model" for interpreting ILD in noise.
  • To investigate the influence of interaural correlation on ILD thresholds.
  • To compare ILD thresholds with level discrimination thresholds.

Main Methods:

  • Measured human ILD thresholds using correlated, anticorrelated, and uncorrelated noise stimuli.
  • Measured thresholds for level discrimination based on loudness.

Related Experiment Videos

  • Compared experimental data with predictions from the level-meter model.

    • Main Results:

    • The level-meter model predictions were accurate within approximately 0.5 dB.
    • Level discrimination thresholds were consistently higher than ILD thresholds.
    • ILD thresholds for uncorrelated noise were slightly elevated compared to correlated noise.

    Conclusions:

    • The level-meter model provides a good approximation for ILD in noise.
    • A modified "loudness-meter model" incorporating temporal integration better explains variations in thresholds.
    • Auditory processing of noise level is largely independent of interaural correlation but influenced by temporal integration.
