DESCRIPTION (provided by applicant): According to recent population estimates made by the U.S. Census Bureau, about 39 million Americans are over 65 years of age, representing 13% of the U.S. Approximately 35% of those over age 65 in the U.S., or about 13.6 million older Americans, have a significant hearing loss that is sufficient to make them hearing-aid candidates. Yet, only about 20% of those who could benefit from hearing aids actually seek them out. Limitations in the accessibility and affordability of hearing health care seem to be primary factors underlying the low percentage of older Americans who purchase hearing aids. The purchase price of the hearing aids and the typical service- delivery model represent key factors that appear to limit the accessibility and affordability of hearing aids. As the production costs of the devices themselves are fairly low, the justification for the higher purchase prices is often grounded in the professional services provided in the selection, programming, fitting and evaluation of the devices. This project proposes to conduct research that would provide new knowledge about the impact of purchase price and service-delivery model on hearing-aid outcomes. The proposed study will acquire this knowledge through a Phase-II double-blinded, placebo-controlled, randomized clinical trial with five parallel branches. In addition to a placebo branch, the remaining four branches represent factorial combinations of service-delivery model (current best practices and over-the-counter simulation) and purchase price (low and typical). Non-inferiority analyses will be performed to compare the outcomes of the current best-practices model to alternative combinations of service-delivery model and purchase price. Based on the results obtained, the findings could have considerable impact on the accessibility and affordability of hearing health care for older adults with mild-to-moderate hearing loss.

描述（由申请人提供）：根据美国人口普查局最近的人口估计，大约有3900万美国人年龄在65岁以上，占美国人口的13%。在美国，大约35%的65岁以上的人，或大约1360万美国老年人，有严重的听力损失，足以使他们成为助听器的候选人。然而，那些可以从助听器中受益的人中，只有大约20%的人真正去找了助听器。听力保健的可及性和可负担性方面的限制似乎是美国老年人购买助听器比例低的主要因素。助听器的购买价格和典型的服务交付模式是限制助听器可及性和可负担性的关键因素。作为生产
