NCT02323932 | Unknown

• 1 other identifier: BZ0085
• Study Type: interventional
• Target: 30

Brief Summary

The purpose of this study is to evaluate the benefit of bimodal hearing and bilateral cochlear implant hearing in comparison to unilateral cochlear implant hearing in the perception of speech intonation.

Conditions

Hearing Loss

Outcome Measures

Primary Outcomes (1)

• The amount of change in the fundamental frequency that was required in order to identify a question

  12 months

Study Arms (2)

Bilateral Cochlear implant users

ACTIVE COMPARATOR

The perception of intonation will be assessed through the use of 2 tests. In the first test, listeners will have to identify statements and yes/no questions that will be presented by male and female talkers in the background of four- talkers-babble noise comprised of two females and two males. In the second test, listeners will be presented with gradual changes in the fundamental frequency of a sentence. They will be required to identify the sentence with each of the changes as a statement or a question. Each of the 2 tests will be presented in three listening conditions: each of the CI alone and bilateral (CI/CI) conditions.

Behavioral: Perception of correct intonation identification

Bimodal Cochlear implant users

ACTIVE COMPARATOR

The perception of intonation will be assessed through the use of 2 tests. In the first test, listeners will have to identify statements and yes/no questions that will be presented by male and female talkers in the background of four- talkers-babble noise comprised of two females and two males. In the second test, listeners will be presented with gradual changes in the fundamental frequency of a sentence. They will be required to identify the sentence with each of the changes as a statement or a question. Each of the 2 tests will be presented in three listening conditions: CI alone, HA alone and bimodal (CI/HA) conditions.
