Spectral weighting functions for localization of complex sound. II. The effect of competing noise.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Spectral weighting of sound localization cues was measured in the presence of three levels of competing noise presented in the free field. Target stimuli were complex tones containing seven tonal components, presented from an ∼120° range of frontal azimuths. Competitors were two independent Gaussian noises presented from 90° left and right azimuth at one of three levels yielding +9, 0, and -6 dB signal-to-noise ratio. Results revealed the greatest perceptual weight for components within the interaural time difference (ITD) "dominance region," which was found previously to peak around the 800-Hz component in quiet [Folkerts and Stecker (2022) J. Acoust. Soc. Am. 151, 3409-3425]. Here, peak weights were shifted toward lower-frequency components (i.e., 400 Hz) in all competing noise conditions. These results contradict the hypothesis of a shift in the peak weights toward higher frequencies based on previous behavioral localization performance in competing noise but are consistent with binaural cue sensitivity, availability, and reliability; measured low-frequency ITD cues within the dominance region were least disrupted by the presence of competing noise.
