AB  - Adults with bilateral cochlear implants (BiCIs) receive benefits in localizing
      stationary sounds when listening with two implants compared with one; however,
      sound localization ability is significantly poorer when compared to normal
      hearing (NH) listeners. Little is known about localizing sound sources in motion,
      which occurs in typical everyday listening situations. The authors considered the
      possibility that sound motion may improve sound localization in BiCI users by
      providing multiple places of information. Alternatively, the ability to compare
      multiple spatial locations may be compromised in BiCI users due to degradation of
      binaural cues, and thus result in poorer performance relative to NH adults. In
      this study, the authors assessed listeners' abilities to distinguish between
      sounds that appear to be moving vs stationary, and track the angular range and
      direction of moving sounds. Stimuli were bandpass-filtered (150-6000 Hz) noise
      bursts of different durations, panned over an array of loudspeakers. Overall, the
      results showed that BiCI users were poorer than NH adults in (i) distinguishing
      between a moving vs stationary sound, (ii) correctly identifying the direction of
      movement, and (iii) tracking the range of movement. These findings suggest that
      conventional cochlear implant processors are not able to fully provide the cues
      necessary for perceiving auditory motion correctly.
