Brief Summary

Communication on telephone is challenging for people with hearing loss. For hearing aid users, for instance, the inventions for improving speech intelligibility on the phone range from an integrated tele coil and individual hearing programs to specially designed phone devices. No formal studies involving these devices have been carried out with CI users. Thus, this comparative study includes hearing aid as well as CI and bimodal users to evaluate different hearing solutions for communication on telephone in terms of intelligibility and ease of use.

Outcome Measures

Primary Outcomes (1)

  • speech reception threshold (SRT) assessment with audiological measures

    differences in speech reception threshold (SRT) on the phone in the presence of background noise between the Phonak DECT phone and a standard phone will be assessed with audiological measures.

    6 months

Secondary Outcomes (1)

  • Subjective ratings assessment with scaling
