项目摘要

GRANT=R556222-01 This research is directed towards improving hearing aid fitting for older adults. Despite substantial improvements in hearing aid technology, the hearing aid take-up rate, and the satisfaction with fitted hearing aids has not improved in the last decade. This is partly due to a failure by the research community to produce and disseminate updated fitting methods that facilitate the ability of practitioners to capitalize on the potential of existing new technologies. The two experiments in this proposal will produce guidelines to assist clinicians to make scientifically based decisions about amplification needs, based on the results of tests conducted before the fitting. The first experiment bridges the gap between laboratory research and clinical in selection of high frequency gain characteristic. Recent studies have demonstrated that, for some individuals with high-frequency hearing loss, high frequency amplification is actually detrimental rather than helpful. There is a pressing need for a clinically practical method that would validly identify patients for whom high-frequency gain is contraindicated. The study assesses the prevalence of such patients, and evaluates two new clinical procedures that have been developed to identify these individuals. The two procedures are used to identify experimental and control groups comprising 20 pairs of subjects. Each subject is fitted with a hearing aid that allows comparison of two amounts of high-frequency gain. Subjects undergo laboratory testing and a field trial to determine which high-frequency gain setting is better. Results show whether the two new clinical procedures yield accurate prediction of optimal high-frequency gain. The second experiment explores the indications for bilateral (binaural) hearing aid fittings for older adults with bilateral hearing loss. About 20 to 30% of bilaterally fitted individuals actually elect to wear only one hearing aid. For these individuals, resources allocated to hearing aid purchase would have been more effectively used for alternate rehabilitation methods. It is not clear why some patients prefer one hearing aid over two, or which patients will fall into this category. This study evaluates outcomes of 100 bilateral hearing aid fittings over a three-month period. Logistic regression is used to develop a model in which binaural summation, binaural integration, binaural interference, and attitudes towards hearing aids and hearing loss are combined to predict which individuals will ultimately prefer to use one hearing aid rather than two.

授予=R556222-01 这项研究旨在改善老年人的助听器验配。尽管助听器技术取得了显着进步，但助听器的使用率以及对助听器佩戴的满意度在过去十年中并未得到改善。部分原因是研究界未能制定和传播更新的验配方法，以促进从业者利用现有新技术潜力的能力。该提案中的两个实验将产生指导方针，以帮助临床医生根据拟合前进行的测试结果做出有关放大需求的科学决策。第一个实验在高频增益特性的选择方面弥合了实验室研究和临床之间的差距。最近的研究表明，对于一些高频听力损失的人来说，高频放大实际上是有害的而不是有益的。迫切需要一种临床实用的方法来有效识别禁忌高频增益的患者。该研究评估了此类患者的患病率，并评估了为识别这些患者而开发的两种新的临床程序。这两种程序用于识别由 20 对受试者组成的实验组和对照组。每个受试者都配备了助听器，可以比较两个高频增益。受试者接受实验室测试和现场试验，以确定哪种高频增益设置更好。结果表明这两种新的临床程序是否能准确预测最佳高频增益。第二个实验探讨了双耳听力损失老年人的双耳助听器验配适应症。大约 20% 到 30% 的双耳佩戴者实际上选择只佩戴一个助听器。对于这些人来说，分配给购买助听器的资源可以更有效地用于替代康复方法。目前尚不清楚为什么有些患者更喜欢一个助听器而不是两个，也不清楚哪些患者会属于这一类。本研究评估了三个月内 100 次双边助听器验配的结果。逻辑回归用于开发一种模型，其中将双耳求和、双耳整合、双耳干扰以及对助听器和听力损失的态度相结合，以预测哪些人最终更喜欢使用一个助听器而不是两个助听器。
