A Preliminary Study of the Effects of Attentive Music Listening on Cochlear Implant Users' Speech Perception, Quality of Life, and Behavioral and Objective Measures of Frequency Change Detection.

摘要: Introduction Most cochlear implant (CI) users have difficulty in listening tasks that rely strongly on perception of frequency changes (e.g., speech noise, musical melody perception, etc.). Some previous studies using behavioral or subjective assessments shown short-term music training can benefit CI users' and speech. Electroencephalographic (EEG) recordings may reveal the neural basis for benefits users. Objective To examine effects hearing outcomes a comprehensive test battery evaluation, tests, EEG measures. Design Twelve adult were recruited home-based program focused attentive to genres materials an emphasis melody. The participants used streaming (i.e., Pandora) downloaded onto personal electronic devices training. attentively listened through direct audio cable Bluetooth streaming. schedule was 40 min/session/day, 5 days/week, either 4 8 weeks. pre-training post-training tests included: thresholds, Speech, Spatial Qualities Hearing Scale (SSQ12) questionnaire, psychoacoustic change detection threshold (FCDT), recognition (CNC words, AzBio sentences, QuickSIN), responses tones contained different magnitudes changes. Results All except one finished 4- 8-week training, resulting dropout rate 8.33%. Eleven performed all two who did not participate tests. showed significant improvement FCDTs as well performance CNC QuickSIN after (p 0.05). larger cortical auditory evoked potentials (CAEPs) seven nine participants, suggesting better processing both stimulus onset within-stimulus Conclusion These preliminary data suggest extensive, improve Further include sample size control groups are warranted determine efficacy
