However, the interplay of interaural attenuation and time delay may result in different responses in each ear; thus, greater challenges for unilateral BAHD users.<\/jats:p><jats:p>To assess the auditory performance of BAHD users with unilateral and bilateral fitting regarding speech recognition in silence and noise and sound localization.<\/jats:p><jats:p>Cross-sectional study. Unilateral BAHD users treated at a Brazilian public hospital underwent a speech recognition test, containing a list of monosyllables at 65dBSPL in silence and noise (S\/N ratio\u2009=\u20090dB). The sound localization test employed eight speakers arranged at 45\u00b0 distance. A recorded trisyllabic word served as the stimulus. For bilateral fitting, an elastic band with a device similar to the implant was used; patients underwent the same tests under identical conditions.<\/jats:p><jats:p>Sixteen patients were assessed (mean age\u2009=\u200924.2 years). The average monosyllable recognition in silence rate was 71.5% in unilateral fitting and 78.2% in bilateral fitting. In noise, 61% in unilateral fitting and 72.2% in bilateral fitting. The mean angular deviation for the sound localization test was 80.48\u00b0 in unilateral fitting and 68.08\u00b0 in bilateral fitting.
