This meta-analysis investigates the compares the effect of using an FM receiver (e.g., traditional soundfield, desktop soundfield, and direct-audio input (DAI) frequency-modulated (FM) systems) with cochlear implants (CI) to CI alone on speech recognition outcomes in children and adtuls with monaural CIs.

The meta-analysis revealed the following:<div><ul> <li>Speech recognition significantly improved in noise for all types of FM receivers relative to no FM system use.</li> <li>Speech recognition significantly improved in noise for desktop and direct audio input FM receivers relative to cochlear implant use alone.</li> <li>There was not statistically significant improvement of speech recognition for traditional soundfield systems relative to cochlear implant use alone.</li></ul></div>
