Lateralization at high frequencies based on interaural time differences
TLDR
In many conditions of listening, sensitivity to interaural time differences at high frequencies compares favorably with sensitivity at low frequencies—good performace requires only tens of microseconds of interaurally time delay.Abstract:
Sensitivity to interaural time differences at high frequencies is demonstrated in a number of experiments. Two types of waveforms are used—bands of noise and two‐tone complexes. Variables studied are rate and depth of fluctuation of the envelope, overall intensity, and additivity of interaural time information across frequency regions. In many conditions of listening, sensitivity to interaural time differences at high frequencies compares favorably with sensitivity at low frequencies—good performace requires only tens of microseconds of interaural time delay.Subject Classification: [43]65.62, [43]65.68.read more

Mechanisms of Sound Localization in Mammals
TL;DR: Recent evidence concerning the nature of the neural representation of auditory space in the mammalian brain is reviewed and advances in the understanding of mammalian subcortical processing of auditory spatial cues that challenge the "textbook" version of sound localization are elaborate.
Journal ArticleDOI
Periodicity coding in the auditory system.
TL;DR: The present review summarizes the present knowledge about representation and processing of periodic signals, from the cochlea to the cortex in mammals, and in homologous or analogous anatomical structures as far as these exist and have been investigated in other animals.

Listener weighting of cues for lateral angle: The duplex theory of sound localization revisited
TL;DR: The virtual auditory space technique was used to quantify the relative strengths of interaural time difference (ITD), Interaural level difference (ILD), and spectral cues in determining the perceived lateral angle of wideband, low-pass, and high-pass noise bursts.

Processing of binaural stimuli by cat superior olivary complex neurons
TL;DR: In both LSO and MSO it seems that integration of information higher in the CNS from a population of these cells is necessary for unambiguous coding of sound source direction, especially when stimulated with noise bursts or non-BF tones.

Enhancing sensitivity to interaural delays at high frequencies by using "transposed stimuli".
TL;DR: In this paper, threshold ITDs were measured using three types of stimuli: (1) low-frequency pure tones; (2) 100% sinusoidally amplitude-modulated (SAM) high-frequency tones, and (3) special, “transposed” highfrequency stimuli whose envelopes were designed to provide the highfrequency channels with information similar to that available in lowfrequency channels.
