Degree of Benefit From Low-Frequency Acoustic Amplification Using the Advanced Bionics Acoustic Earhook

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT04041596

Brief Summary:
The primary objective of this study is to obtain a greater understanding of the range in benefit from acoustic amplification combined with electric stimulation in cochlear implant recipients with low-frequency hearing who do not currently use the commercially approved Advanced Bionics Acoustic Earhook. The aims of this study are to 1) obtain subjective sound quality judgements of recorded speech and music samples, 2) assess vocal emotion perception, and 3) evaluate post-operative speech perception and sound field detection thresholds in CI recipients both with and without use of the acoustic ear hook.

Intervention Details:
  • Device: Advanced Bionics' Acoustic Earhook
    designed to deliver acoustic amplification through the modular attachment of the Naída CI Q90 AcoustiEarhook, while also delivering electrical stimulation along the full range of the implanted Advanced Bionics electrode.

Primary Outcome Measures :
  1. Change in Speech recognition testing, with and without acoustic earhook [ Time Frame: 3 Months, 6 Months, 12 Months ]
    5-alternative identification task to measure vocal emotion recognition (Toronto Emotional Speech Test (TESS) at initial fitting, and 3, 6, and 12 months after fitting

  2. Change in Sound quality judgements, with and without acoustic earhook [ Time Frame: 3 Months, 6 Months, 12 Months ]
    Ratings of sound quality (Judgement of Sound Quality {JSQ} test) of speech and music samples at initial fitting, and 3, 6, and 12 months after fitting

  3. Change in Vocal emotion perception task, with and without acoustic earhook [ Time Frame: 3 Months, 6 Months, 12 Months ]

Ages Eligible for Study:   18 Years to 99 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Ability to provide informed consent
  • Implanted with an Advanced Bionics Advanced Bionics HiRes Ultra, 90K, or CII implant, and using a Naída Q90 sound processor
  • 18 years of age or older with post-lingual hearing loss
  • Aided open-set speech recognition scores greater than 30% correct in quiet in the ear to be tested
  • Unaided low frequency audiometric hearing thresholds of 90 dB HL or better at .125, .25, and .5 kHz
  • Participants must have a working understanding of and ability to verbalize in English as the evaluation measures are available exclusively in English

  • Willingness to participate in all scheduled procedures outlined in the protocol

Exclusion Criteria:

  • Exclusive use of a body worn external sound processor
  • Deafness due to central auditory lesion or cochlear nerve deficiency, diagnosis of auditory neuropathy/dys-synchrony in either the implanted or the contralateral ear
  • Postoperative unaided low frequency audiometric hearing thresholds in the implanted ear exceeding 90 dB HL at any frequency from 125 - 500 Hz.
  • Presence of other conditions that could affect performance on outcome measures or otherwise confound or interfere with study participation or outcomes measures.
