Binaural hearing in cochlear implant (CI) users can be achieved either by bilateral implantation or bimodally with a contralateral hearing aid (HA). Binaural-bimodal hearing has the advantage of complementing the high-frequency electric information from the CI by low-frequency acoustic information from the HA. We examined the contribution of a contralateral HA in 25 adult implantees to their perception of fundamental frequency-cued speech characteristics (initial consonant voicing, intonation… 
Fundamental Frequency Information for Speech Recognition via Bimodal Stimulation: Cochlear Implant in One Ear and Hearing Aid in the Other
TLDR
The higher scores obtained in the CI/HA condition than with CI alone in both of the task-specific tests suggested that the use of a contralateral HA provides improved low-frequency information, resulting in better performance by theCI/HA users.
Effects of Removing Low-Frequency Electric Information on Speech Perception With Bimodal Hearing.
TLDR
It is suggested that reducing low-frequency overlap of the CI and contralateral hearing aid may improve performance in quiet for some bimodal listeners with better hearing.
Bimodal Benefits Revealed by Categorical Perception of Lexical Tones in Mandarin-Speaking Kindergarteners With a Cochlear Implant and a Contralateral Hearing Aid.
TLDR
The enhanced CP results with bimodal listening provide clear evidence for the clinical practice to fit a contralateral HA in the nonimplanted ear in kindergarteners with unilateral CIs with direct benefits from the low-frequency acoustic hearing.
The Benefits of Bimodal Aiding on Extended Dimensions of Speech Perception: Intelligibility, Listening Effort, and Sound Quality
TLDR
The bimodal listening situation was rated to sound more voluminous, less tinny, and less unpleasant than CI alone, and a reduction in effort on top of intelligibility at the highest tested signal-to-noise ratio was found.
Perception of vowels and prosody by cochlear implant recipients in noise.
TLDR
Results indicated that vowel recognition was significantly better than prosody recognition in both listener groups in both quiet and noise, and that question/statement discrimination was the most difficult task for CI listeners in noise.
From Hearing with a Cochlear Implant and a Contralateral Hearing Aid (CI/HA) to Hearing with Two Cochlear Implants (CI/CI): A Within-Subject Design Comparison
TLDR
Couning regarding contralateral implantation forCI/HA users with severe-to-profound hearing loss in the HA ear should consider individual functional needs, and cover expectations about the expected trade-off between gaining improved understanding and speech lateralization in challenging listening conditions and losing some low-frequency cues still available with CI/HA hearing.
Are There Real-world Benefits to Bimodal Listening?
TLDR
Findings support the idea that there are additional advantages to bimodal listening after implantation other than speech recognition measures, which are at risk of being lost if considering bilateral implantation.
Multisensory emotion perception in congenitally, early, and late deaf CI users
TLDR
The results suggest that CI users acquire multisensory interactions to some degree, even after congenital deafness, and when judging affective prosody they appear impaired and more strongly biased by concurrent facial information than typically hearing individuals.
A comparison of bilateral cochlear implantation and bimodal aiding in severely-profoundly hearing-impaired adults: head movements, clinical outcomes, and cost-effectiveness
Under current guidelines in the UK, eligible adults can receive a single cochlear implant through the National Health Service. Should they wish to aid their non-implanted ear they can either use an
Self-Assessment of Unilateral and Bimodal Cochlear Implant Experiences in Daily Life
TLDR
Comparisons between both groups showed no difference in self-rated disability, hearing handicap or general quality of life, however within the group of bimodal listeners, participants did report a significant benefit of bIModal hearing ability in various daily life listening situations.

Perception of suprasegmental speech features via bimodal stimulation: cochlear implant on one ear and hearing aid on the other.
TLDR
A significant bimodal advantage for perception of all suprasegmental features is found, most probably due to the better low-frequency acoustic hearing that is provided by the HA.
Speech Perception Benefit for Children with a Cochlear Implant and a Hearing Aid in Opposite Ears and Children with Bilateral Cochlear Implants
TLDR
Findings encourage the use of bimodal and bilateral implant fittings for children, provide insight into the individual variability in bIModal outcome, and enhance understanding of the differences between an HA and a 2nd CI when used together with an implant in the opposite ear.
Advantage of bimodal fitting in prosody perception for children using a cochlear implant and a hearing aid.
TLDR
Compared to the implant only condition, bimodal fitting improved the perception of intonation, and even with a hearing aid, the implanted group required exaggerated F0 excursions to perceive a pitch accent and to identify a question.
Production and Perception of Speech Intonation in Pediatric Cochlear Implant Recipients and Individuals with Normal Hearing
TLDR
Pediatric CI recipients do not show mastery of speech intonation in their production or perception to the same extent as their NH peers, and intersubject variability exists in pediatric CI recipients' mastery levels in the production and perception of speechintonation contrasts.
Advantages of binaural hearing provided through bimodal stimulation via a cochlear implant and a conventional hearing aid: A 6-month comparative study
TLDR
The study data demonstrate the additional benefit derived from continued use of a contralateral hearing aid (HA) post-cochlear implantation for speech recognition ability in quiet and in noise and recommends bimodal stimulation postoperatively for experienced HA users.
Binaural–bimodal hearing: Concomitant use of a unilateral cochlear implant and a contralateral hearing aid
TLDR
The benefit obtained with a contralateral hearing aid (HA) in unilateral cochlear implantees improves over time, at least during the first year after implantation, according to patients with residual hearing in the non-implanted ear.
Hearing progress and fluctuations in bimodal–binaural hearing users (unilateral cochlear implants and contralateral hearing aid)
TLDR
Hearing progress over the first 3 years after unilateral cochlear implantation in users who had residual hearing in the non-implanted ear at the time of surgery and continued to use a HA in that ear thereafter was examined.
Perception of suprasegmental features of speech by children with cochlear implants and children with hearing AIDS.
TLDR
Perception of suprasegmental features of speech by 30 prelingual children with sensorineural hearing loss revealed that the two HA groups significantly outperformed the CI group in perceiving both intonation and stress.
Should a Hearing Aid in the Contralateral Ear Be Recommended for Children with a Unilateral Cochlear Implant?
TLDR
Preoperatively available audiometric parameters are not reliable predictors of bimodal benefit in candidates for cochlear implantation and children with unilateral implants benefit from bIModal fitting on speech tests.
Speech perception for adults who use hearing aids in conjunction with cochlear implants in opposite ears.
TLDR
Results showed that participants with poorer aided thresholds in the mid-to-high frequencies demonstrated greater bimodal benefit, and it is possible that the mid to-high frequency information provided by the hearing aids may be conflicting with the cochlear implants.
