 DESCRIPTION (provided by applicant): The high cost of hearing aids is a major barrier underlying low treatment rates for hearing loss. Self-fitting of amplification can reduce the cost of service delivery and follow-up by allowing users to adjust amplification for their hearing needs and listening environments. The goal of this project is to determine the efficacy of self- fitting protocols by which users can (1) make initial adjustments to the electroacoustic and signal-processing characteristics of amplification and (2) modify those characteristics on the basis of experience, and in response to changing acoustic environments. The project involves interdisciplinary collaboration between audiologists, hearing scientists, and engineers. In the R21 phase, we will evaluate the efficacy of a self-adjustment protocol using a computer simulation with built-in sounds. Simultaneously, we will develop a system with ear-level assemblies and on-line speech processing capabilities. In the R33 phase, modifications to the self-fitting protocol will be evaluated, with the goal of optimizing outcomes while maintaining simplicity for independent operation by novice users. In parallel, engineering will incorporate the findings into a wearable device and add sound-input characterization and noise-management features. The sound-input characterization feature will collect and log sound-input data before, during and after user self-adjustment. Efficacy of the wearable system will be evaluated in the laboratory and in field studies: 1) to compare objective and subjective outcomes for self-adjusted and audiologist-adjusted settings, and 2) to evaluate self-adjustment patterns in everyday environments and determine the influence of acoustic input and user-related factors such as sound tolerance, personality, and working memory.

 描述（由申请人提供）：助听器的高成本是听力损失治疗率低的一个主要障碍。扩音器的自适配可以通过允许用户根据自己的听力调整扩音器来降低服务提供和随访的成本。需要 该项目的目标是提高自适配协议的有效性，用户可以通过该协议（1）对放大的电声和信号处理特性进行初步调整，以及（2）根据经验修改这些特性。 ，并响应不断变化的声学环境。该项目涉及听力学家、听力科学家和工程师之间的跨学科合作。在 R21 阶段，我们将使用内置声音的计算机模拟来评估自我调节协议的功效。同时，我们将开发一个具有耳级组件和在线语音处理功能的系统，在R33阶段，将评估对自拟合协议的修改，目标是优化结果，同时保持新手独立操作的简单性。同时，工程将纳入用户。 声音输入特性将在用户自我调整之前、期间和之后收集和记录声音输入数据，并添加声音输入特性和噪声管理功能。实验室和现场研究：1) 比较自我调整和听力学家调整设置的客观和主观结果，2) 评估日常环境中的自我调整模式并确定声学输入和声音输入的影响用户相关因素，例如声音耐受性、个性和工作记忆。
