Randomized trial examines sound localization in different rooms, highlighting the role of reverberation and frequency.

This research investigates how sound localization varies in different reverberant environments based on frequency.
Six blindfolded listeners judged sine tone locations in three rooms with different reverberation times.
Ear canals were fitted with microphones to record tones and calculate interaural time differences (ITD) and interaural level differences (ILD).
Correlations between listener responses and both ITD and ILD were computed for analysis.
ITD dominated at low frequencies (below 400 Hz) while ILD dominated at high frequencies (above 600 Hz).
Reverberation increased spatial dependencies of ITD and ILD, leading to predictable relationships under specific conditions.
Effective ITD and ILD measurements were made with a dummy head, showcasing a crossover frequency between 400 and 600 Hz.

William Hartmann (2025) studied this question.
