DESCRIPTION (provided by applicant): This application requests funds to develop software that will facilitate the design, optimization, and assessment of novel sound processing strategies for implantable auditory prostheses. The software will be designed to interface with existing research platforms that enable diagnostic assessment and control applications. Utilities will be developed that allow users to incorporate custom signal processing and measurement modules into the software framework. Sensimetrics has completed substantial work towards the development of such software and Phase 1 work is directed at translating a current version into a comprehensive software package. Towards this end, the following specific aims must be met: 1) Expand hardware and software support for auditory prosthesis devices. The current software has been designed for use with Cochlear Corporation systems; effort will be directed towards providing support for research devices that control Advanced Bionics Corporation and MedEl Corporation systems. 2) Expand software functionality. Work is outlined to provide interfaces for developing and integrating new processing and analysis modules. 3) Improve software design. Work is outlined towards improving overall design of the software. During the first year of Phase 1, two formative evaluations of the software will be conducted in collaboration with clinical and academic partners. The first will be conducted in collaboration with Children's Hospital Boston to investigate clinically relevant measures of synchrony in bilateral cochlear implant recipients. The second formative evaluation will be conducted in collaboration with the University of Minnesota and will investigate relations between psychophysical and speech reception measures in auditory brainstem and midbrain implant recipients. During the second year, these formative evaluations will be brought into summative evaluations in which the focus will shift away from software development and into clinical evaluation. As this shift occurs, the project's focus will also shift to new academic and clinical partnerships aimed at further development of the software. The planned developments include interfacing the software with a PDA processor under development at the University of Texas at Dallas and extending the software for use in as an auditory training resource. The objective is to produce a flexible and modular framework that can be readily reconfigured for new applications. Phase 1 will deliver a prototype containing the necessary utilities that can be used flexibly for diagnostic assessment and control of auditory prostheses. PUBLIC HEALTH RELEVANCE: This application requests funds to develop software that will facilitate the design, optimization, and assessment of novel sound processing strategies for implantable auditory prostheses. The software will be designed to interface with existing research platforms that enable diagnostic assessment and control applications. This software development project is framed around two formative evaluations directed at synchronization of bilateral cochlear implants and at sound processing design for auditory brainstem and midbrain implants.

描述（由申请人提供）： 该申请要求资金开发软件，以促进植入式听觉假体的新型声音处理策略的设计，优化和评估。该软件将被设计为与现有的研究平台接口，使诊断评估和控制应用程序。将开发实用程序，允许用户将自定义信号处理和测量模块纳入软件框架。Sensimetrics已经完成了此类软件开发的大量工作，第一阶段的工作旨在将当前版本转换为全面的软件包。为此，必须实现以下具体目标：1）扩大对听觉假体设备的硬件和软件支持。目前的软件设计用于与Cobriar Corporation系统配合使用;将努力为控制Advanced Bionics Corporation和MedEl Corporation系统的研究设备提供支持。2)扩展软件功能。概述了为开发和集成新的处理和分析模块提供接口的工作。3)改进软件设计。工作概述了改进软件的总体设计。在第一阶段的第一年，将与临床和学术合作伙伴合作对软件进行两次形成性评估。第一项研究将与波士顿儿童医院合作进行，以调查双侧人工耳蜗植入者的临床相关同步措施。第二次形成性评价将与明尼苏达大学合作进行，并将调查听觉脑干和中脑植入物接受者的心理物理和言语接受措施之间的关系。在第二年，这些形成性评价将被纳入总结性评价，其中重点将从软件开发转移到临床评价。随着这种转变的发生，该项目的重点也将转移到新的学术和临床合作伙伴关系，旨在进一步开发软件。计划中的开发包括将软件与达拉斯得克萨斯大学正在开发的PDA处理器连接，并将软件扩展为听觉训练资源。其目标是产生一个灵活的模块化框架，可以很容易地重新配置新的应用程序。第一阶段将提供一个原型，其中包含必要的实用程序，可以灵活地用于诊断评估和控制听觉假体。 公共卫生相关性： 该申请要求资金开发软件，以促进植入式听觉假体的新型声音处理策略的设计，优化和评估。该软件将被设计为与现有的研究平台接口，使诊断评估和控制应用程序。该软件开发项目围绕两个形成性评价框架，分别针对双侧人工耳蜗植入体的同步和听觉脑干和中脑植入体的声音处理设计。
