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 after passing recordings through a 400 Hz auditory filter (circles in upper panel). Red and blue lines show right and left and right amplitude envelopes in the lower panel.
Recordings of 10 statistically independent noises, each passed through a 400 Hz auditory filter, prompting distinct modulations and ILD patterns across the recordings.
