This systematic review investigates the impact of hearing assistive devices (e.g., hearing aids, cochlear implants, bimodal stimulation) on prosodic cues in children and adults with hearing loss. Descriptive information regarding the impact of hearing loss on perception of prosody is also included within this systematic review, however, is outside of the scope of the Evidence Maps.

Findings demonstrated that use of hearing aids, cochlear implants, or bimodal stimulation was generally not associated with significant remediation of prosodic perception impairments in individuals with hearing loss. However, in a limited number of studies, greater improvements in perception of prosody were noted in individuals with bimodal stimulation when compared to individuals with bilateral cochlear implantation. Limitations to this review include significant heterogeneity between studies, an overall paucity of evidence, and lack of reporting of sample sizes and potential for biases. Further research is indicated.
