DESCRIPTION (provided by applicant): The overall goal of this study is to develop a head tracking procedure for the automated assessment of hearing in infants using Visual Reinforcement Audiometry (VRA). The head tracking procedure will be incorporated into the Intelligent Visual Reinforcement Audiometry (IVRA) system from Intelligent Hearing Systems Corp. The IVRA system currently provides automated stimulus delivery, data recording, and reinforcement but relies on an examiner to judge the presence of responses. Because examiners can vary in their response criterion, current VRA and IVRA results include a certain amount of examiner bias, which can increase test variability and compromise test validity. The proposed automated head tracking procedure will allow for automated recording of response occurrence and reaction time as a function of stimulus intensity and frequency and eliminate examiner bias and increase the reliability, validity and availability of VRA. The Phase I clinical study will involve 30 infants. PUBLIC HEALTH RELEVANCE: Visual Reinforcement Audiometry (VRA) is an important assessment tool in determining the hearing status of infants. The implementation of the proposed automated head tracking procedure in VRA is expected to greatly improve the clinical reliability, validity and utility of VRA testing. As such, the proposed work will greatly impact public health by developing better VRA testing systems.

描述（由申请方提供）：本研究的总体目标是开发一种头部跟踪程序，用于使用视觉强化测听法（弗拉）自动评估婴儿听力。头部跟踪程序将被纳入智能听觉系统公司的智能视觉强化测听（IVRA）系统。IVRA系统目前提供自动刺激传递、数据记录和强化，但依赖于检查员来判断反应的存在。由于检查者的反应标准可能不同，因此当前的弗拉和IVRA结果包含一定量的检查者偏倚，这可能增加测试的变异性并损害测试的有效性。拟议的自动头部跟踪程序将允许自动记录的反应发生和反应时间作为刺激强度和频率的函数，消除考官的偏见，并增加可靠性，有效性和可用性的弗拉。I期临床研究将涉及30名婴儿。 公共卫生相关性：视觉强化测听（弗拉）是确定婴儿听力状况的重要评估工具。在弗拉中实施拟议的自动头部跟踪程序有望大大提高弗拉测试的临床可靠性、有效性和实用性。因此，拟议的工作将通过开发更好的弗拉测试系统对公共卫生产生重大影响。
