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.
对患者单耳与双耳助听器的偏好进行了研究，以评估这两种类型的助听器在主观上的差异。研究对象为30例首次佩戴助听器的双侧听力障碍患者。研究对象分别佩戴单耳和双耳助听器，每种佩戴1小时，各佩戴2天。随后还有3天，佩戴方式由研究对象自行选择交替。在每个实验阶段后，研究对象报告其偏好和主观感受。在参与研究3个月后进行访谈，以确定实际的助听器使用情况。90%的研究对象出于一致的相似原因更喜欢双耳放大。结果还表明，在初始试验期内偏好的一致性可能预示着对助听器成功的适应和使用。研究结果表明，常规佩戴单耳助听器的做法可能无法为许多患者提供最佳的佩戴效果。
