Acoustic Localization By Interaural Level Difference [PDF]
Interaural level difference (ILD) is an important cue for acoustic localization. Although its behavior has been studied extensively in natural systems, it remains an untapped resource for computer-based systems. We investigate the possibility of using ILD for acoustic localization, deriving constraints on the location of a sound source given the ...

Perception of across-frequency interaural level differences [PDF]
The interaural level difference (ILD) is an important cue for the localization of sound sources. Just noticeable differences (JND) in ILD were measured in 12 normal hearing subjects for uncorrelated noise bands with a bandwidth of 1∕3 octave and a different center frequency in both ears.

Crocodiles use both interaural level differences and interaural time differences to locate a sound source [PDF]
To explore how crocodilians locate a sound source, two Nile crocodiles (Crocodylus niloticus) were trained to swim towards an acoustic target. Using filtered versions of synthesized stimuli, the respective roles of interaural level differences (ILDs) and interaural time differences (ITDs), which are the two main cues providing information on sound ...

Binaural processing of modulated interaural level differences [PDF]
Two experiments are presented that measure the acuity of binaural processing of modulated interaural level differences (ILDs) using psychoacoustic methods. In both experiments, dynamic ILDs were created by imposing an interaurally antiphasic sinusoidal amplitude modulation (AM) signal on high-frequency carriers, which were presented over headphones. In

Frequency-Invariant Representation of Interaural Time Differences in Mammals [PDF]
Interaural time differences (ITDs) are the major cue for localizing low-frequency sounds. The activity of neuronal populations in the brainstem encodes ITDs with an exquisite temporal acuity of about .

Spatial Mechanisms for Segregation of Competing Sounds, and a Breakdown in Spatial Hearing
We live in complex auditory environments, in which we are confronted with multiple competing sounds, including the cacophony of talkers in busy markets, classrooms, offices, etc.

Interaural time difference processing in the mammalian medial superior olive [PDF]
The dominant cue for localization of low-frequency sounds are microsecond differences in the time-of-arrival of sounds at the two ears [interaural time difference (ITD)].

Two congruent cues are better than one: Impact of ITD–ILD combinations on reaction time for sound lateralization [PDF]
This letter presents a reaction time analysis of a sound lateralization test. Sounds from various directions were synthesized using interaural time–level difference (ITD–ILD) combinations, and human subjects performed left/right detection.

Lateralization of interaural level differences in children with bilateral cochlear implants [PDF]
To investigate the perception of interaural level differences (ILDs) in children with bilateral cochlear implants (BiCIs) and compare them to normal hearing peers. As intracranial shifts in perception of ILDs might have an effect on localization, this was further investigated.ILD responses on four different frequency bands (broadband, low-pass, mid ...

Adaptation of Binaural Processing in the Adult Brainstem Induced by Ambient Noise [PDF]
Interaural differences in stimulus intensity and timing are major cues for sound localization. In mammals, these cues are first processed in the lateral and medial superior olive by interaction of excitatory and inhibitory synaptic inputs from ipsi- and ...
