title: Subjective comparisons of binaural versus monaural amplification.
abstract: Patient preference for monaural versus binaural hearing aids was studied to evaluate the subjective differences noted between these two types of fittings. Subjects were 30 patients with bilateral hearing impairment who were being fit with amplification for the first time. Subjects wore both monaural and binaural hearing aids for controlled periods of 1 hr each and 2 days each. This was followed by an additional 3 days during which the fittings were alternated at the subjects' own discretion. Subjects reported preferences and subjective differences after each experimental phase. Interviews were conducted 3 months after participation in the study to determine actual hearing aid use. Binaural amplification was preferred by 90% of the subjects for consistently similar reasons. Results also suggest that consistency of preferences throughout an initial trial period may be predictive of successful adjustment to and use of amplification. Findings indicate that the routine practice of fitting monaural hearing aids may not provide optimum fittings for many patients.
