Objective:
To assess speech discrimination through line and mobile telephone in cochlear implanted patients.
Material And Methods:
Eighteen patients implanted with a Combi 40+ went through different speech discrimination tests with a line telephone and three mobile telephones, in quiet and noisy environment.
Results:
Mean scores for telephonic speech discrimination were 84-92% using CID sentences, 27-58% using bisyllabic words in quiet environment and 15-41% using bisyllabic words in noisy environment. Among the mobile telephones tested, the Siemens M55 reached the best scores.
Conclusions:
Telephonic speech discrimination is achieved by a significant number of cochlear implanted patients. Certain mobile telephone models appear to be more advisable for these patients.
