Summary

Re-examined how much reverberation harms cochlear implant users' speech understanding, using loudspeaker-based simulations of real rooms at plausible talker distances.

Key findings

  • Notes that earlier studies suggested implant users have almost no tolerance for reverberation and are harmed by both early and late reflections.
  • Measured speech intelligibility with a loudspeaker-based auralisation of a range of real rooms at plausible source-receiver distances, with and without late reflections, instead of the non-individualised binaural simulations used before.
  • Found the effect of reverberation much smaller than earlier studies suggested, especially at short source-receiver distances.
  • Found that, contrary to earlier literature, early reflections may not harm implant users.

Limits

Read from the abstract only; the number of participants and the scores could not be read. Simulated rooms in a laboratory; no assistive listening system was tested.
