The objective of this study is to develop a system capable of objectively determining audiogram configurations in newborn infants using auditory steady-state evoked potentials (ASSEP). The system will address the need to obtain frequency-specific hearing threshold information infants less than six months of age in a fast and efficient manner in order to fit hearing aids. Current ABR technology is inadequate for this purpose primarily due to the lack of threshold specificity and long testing time requirements. The new system will be able to obtain frequency specific information in a very efficient manner utilizing newly developed techniques for ASSEP testing. In the proposed experiments, these techniques will be combined with various threshold-searching and audiogram pattern detection algorithms in order to minimize testing time. The system will be implemented in a completely portable integrated platform capable of performing ABR, OAE and other audiometric functions. The addition of ASSEPs to this platform will provide clinicians with a much needed and very powerful screening and diagnostic tool. Phase I of the study will focus on parameter optimization and initial trials. The performance of the system will be compared to behavioral responses obtained from a large-scale clinical study to be performed during Phase II. PROPOSED COMMERCIAL APPLICATIONS: The proposed device will have an immediate commercial appear and will enable clinicians to determine audiograms in infants less than six months of age.

本研究的目的是开发一个系统，能够客观地确定听力图配置的新生儿使用听觉稳态诱发电位（ASSEP）。该系统将满足以快速有效的方式获得六个月以下婴儿特定频率听阈信息的需求，以便安装助听器。目前的ABR技术不足以达到这一目的，主要是由于缺乏阈值特异性和长的测试时间要求。新的系统将能够获得频率的具体信息，在一个非常有效的方式利用新开发的技术ASSEP测试。在拟议的实验中，这些技术将结合各种阈值搜索和听力图模式检测算法，以尽量减少测试时间。该系统将在一个完全便携式的集成平台上实现，能够执行ABR，OAE和其他听力功能。将ASSEP添加到该平台将为临床医生提供急需的非常强大的筛查和诊断工具。该研究的第一阶段将侧重于参数优化和初步试验。将系统的性能与从II期期间进行的大规模临床研究中获得的行为反应进行比较。拟议的商业应用：拟议中的设备将立即商业化，并将使临床医生能够确定不到六个月大的婴儿的听力图。
