Binaural recordings of broadband noise-bursts played from a loudspeaker in my dining room. Analyses show that cues in some frequency bands resemble ‘ideal’ values before recent reflections arrive. Values then drift and fluctuate due to frequency-specific amplitude modulations, acoustic reflections and background sounds.
Interaural level differences (ILDs) computed at the times of zero-crossings (circles in upper panel). Red and blue lines show right and left and right amplitude envelopes in the lower panel.
Recordings passed through 10 different auditory filters centered between 100 and 1,000 Hz. Modulations differ within each frequency band, prompting different ILD patterns in each band.
