Purpose: The aim of this experiment was to compare, 8 listeners with HP CIs were taken from Loiselle, Dorman, for patients with cochlear implants (CIs), the improvement Yost, Cook, and Gifford (2016), who used the same test for speech understanding in noise provided by a monaural protocol. adaptive beamformer and for two interventions that produced Results: The use of the beamformer resulted in a bilateral input (i.e., bilateral CIs and hearing preservation 31 percentage point improvement in performance; in [HP] surgery). bilateral CIs, an 18 percentage point improvement; and Method: Speech understanding scores for sentences were in HP CIs, a 20 percentage point improvement. obtained for 10 listeners fit with a single CI. The listeners Conclusion: A monaural adaptive beamformer can produce were tested with and without beamformer activated in a an improvement in speech understanding in a complex “cocktail party” environment with spatially separated target noise environment that is equal to, or greater than, the and maskers. Data for 10 listeners with bilateral CIs and improvement produced by bilateral CIs and HP surgery.
