Remote measurement of spectral weighting in sound localization using virtual reality headsets.

Unequal weighting of binaural information across frequency can reduce sensitivity in the presence of competing but uninformative cues ("binaural interference"), a potentially serious problem for listeners who use combined electric and acoustic (EAS) hearing. Here, we used virtual-reality techniques to measure spectral weighting functions (SWF) during localization of simulated EAS stimuli [see van Ginkel et al., 2019, JASA 145, 2445-52]: low-frequency "acoustic" noise bands and high-frequency "electric" click trains.
