Area of Science:

Acoustics
Psychoacoustics
Signal Processing

Background:

Interaural Time Delay (ITD) is crucial for binaural sound source localization.
ITD is calculated from Head-Related Impulse Responses (HRIRs) or Head-Related Transfer Functions (HRTFs).
Existing ITD calculation methods vary in definitions and assumptions.

Purpose of the Study:

To conduct a comprehensive comparative analysis of common ITD calculation methods.
To investigate the variability and spatial differences between these methods.
To identify potential causes for discrepancies in ITD calculations.

Main Methods:

Compared 32 distinct ITD calculation methods and variations.
Utilized HRTF data measured on a KEMAR mannequin and a rigid sphere.
Focused on horizontal plane sound source positions.

Main Results:

Demonstrated significant variability among different ITD calculation methods.
Identified spatial variations in ITD calculation accuracy.
Highlighted the influence of multipath propagation and head/pinnae shadowing on HRIRs.

Conclusions:

The choice of ITD calculation method significantly impacts sound localization accuracy.
Acoustic artifacts, particularly in the contralateral ear, contribute to method variability.
Further research is needed to refine ITD calculation techniques for improved spatial audio applications.
