The sample was composed of 25 adults who had used either a cochlear implant for at least 6 months or a contralateral hearing aid, with a mean age of 46 years. The balancing of the loudness was performed in an acoustic room with the computer's sound box (0\u00b0 azimuth at 70\u2009dB SPL). The instrumental sounds were filtered through eight different frequency bands. The patients used both hearing devices and were asked if the sound was perceived to be louder in one of the ears or centrally. The speech test was evaluated with sentence silence (65\u2009dB SPL) and\/or noise signal ratio of 0\u2009dB\/+\u200910\u2009dB in free field at 0\u00b0 azimuth, before and after balancing.<\/jats:p><jats:p>Results: Out of the 25 patients, 5 failed to achieve balance at every tested frequency, and 3 achieved balance at almost every frequency, except 8\u2009kHz. There was a significant difference between the speech recognition test only in silence before and after balancing.<\/jats:p><jats:p>Conclusion: Most patients achieved sound equalization at all evaluated frequencies under the complex-sound protocol. Additionally, most patients experienced improved speech recognition after balancing.<\/jats:p>","DOI":"10.1055\/s-0040-1712482","type":"journal-article","created":{"date-parts":[[2020,6,23]],"date-time":"2020-06-23T23:23:07Z","timestamp":1592954587000},"page":"e235-e241","source":"Crossref","is-referenced-by-count":3,"title":["Balancing
