start of 1:1-Block public summary

Brief Summary in Lay Language

Patients with Cochlear Implants often have difficulties with cummunication via the telephone. The most likely cause is that most telephones today only transmitt a limited frequency range. This study aims at evaluating a new training paradigm that specifically trains frequencies transmitted via the telephone.

Brief Summary in Scientific Language

Objectives. Speech recognition on the telephone poses a challenge for patients with cochlear implants, since a reduced bandwidth of 0.3 to 3.4 kHz limits spectral information. Targeted auditory training bears the potential to improve the adaption to this special auditory situation. The present study evaluates a home-based training with specifically filtered speech material.

Interventions/Observational Groups

  •   Patients receive auditory training for 10-14 weeks with training material filtered specifically to the frequencies 0.3 - 3.4 kHz (using Heidelberger CI-Trainings-CD). At visit 1, patients are instructed to use the training CD daily for at least 15 minutes to practise understanding of the speech material on the CD.
  •   Patients receive unfiltered auditory training for 10-14 weeks (using Heidelberger CI-Trainings-CD), instructions and the following training period is analogous to arm 1.
