The effect of interaural-level-difference fluctuations on the externalization of sound
The Journal of the Acoustical Society of America, 2013Real-world sound sources are usually perceived as externalized and thus properly localized in both direction and distance. This is largely due to (1) the acoustic filtering by the head, torso, and pinna, resulting in modifications of the signal spectrum and thereby a frequency-dependent shaping of interaural cues and (2) interaural cues provided by the

Analysis and Comparison of Inter-Channel Level Difference and Interaural Level Difference
2016The directional perception of human ear for the sound at horizontal plane mainly depends on binaural cues, Interaural Level Difference ILD, Interaural Time Difference ITD and Interaural Correlation IC. And ILD plays a leading role for human to locate the position of sound with frequency above 1.5i¾?KHz.

Human infants’ sensitivity to interaural level differences
The Journal of the Acoustical Society of America, 1993Infants’ sensitivity to interaural differences was assessed using a lateralization paradigm. Infants aged 5 to 6 months heard speech sounds with interaural level or time differences (ILD, ITD), while an observer made forced choice judgments about the side of the louder (or leading) sound.

Interaural level difference processing as a function of frequency
Journal of the Acoustical Society of America, 2016To localize in the azimuthal plane, humans utilize interaural time differences and interaural level differences (ILDs). For sounds presented in the free field at different azimuthal locations, ILDs generated by the head are complex functions that are frequency dependent and non-monotonic, and are thought to contribute towards sound localization ...

The interaural level difference (ILD) of a lateralized target source may be effectively reduced when the target is presented together with background noise containing zero ILD. It is not certain whether listeners perceive a position congruent with the reduced ILD or the actual target ILD in a lateralization task.

Detection and Lateralization of Interaural Differences of Time and Level by the Blind
Perceptual and Motor Skills, 1974The performance of blind Ss differed from that of sighted Ss on an auditory task in which both binaural cues were present, but in opposition. When the task was lateralization, the blind Ss relied more heavily on interaural time information than on interaural intensity differences, but, unlike sighted Ss, this occurred independent of their relative ...

Differences of Interaural Phase and Level in Detection and Lateralization: 250 Hz
The Journal of the Acoustical Society of America, 1971A narrow band of noise (50 Hz wide centered at 250 Hz) was passed through a phase-shifting network and was then used as both masker and signal. The phase shifter permitted control over the phase angle α at which the signal and the masker were added. The masker was continuously present and was in-phase interaurally N0); the signal could be presented in ...

Across-channel processing of interaural level differences
Journal of the Acoustical Society of America, 2015Interaural level differences (ILDs) are produced when sounds occur away from the midline. The attenuation at the ear that is farther from the source location is frequency dependent and sometimes non-monotonic, resulting in inconsistent ILDs across frequency. It is unclear how the binaural system processes inconsistent ILDs. Ten normal-hearing listeners

The binaural trading ratio (Δt/ΔI) is traditionally measured by opposing an interaural time difference (Δt) with an interaural intensity difference (ΔI) in proportions sufficient for apparent cancellation of the perceptual effects of the two cues. In a previous paper [E. R. Hafter and S. C. Carrier, J. Acoust. Sac. Amer.

Interaural Level Difference Processing in the Lateral Superior Olive and the Inferior Colliculus
Journal of Neurophysiology, 2004Interaural level differences (ILDs) provide salient cues for localizing high-frequency sounds in space, and populations of neurons that are sensitive to ILDs are found at almost every synaptic level from brain stem to cortex. These cells are predominantly excited by stimulation of one ear and predominantly inhibited by stimulation of the other ear ...
