Advanced DSP-Based Hearing Simulator

描述(申请人提供)：建议开发一种综合听力模拟器。模拟器将能够接收声音刺激并输出相应的听觉诱发电位(AEP)和耳声发射(OAE)。该模拟器将有广泛的应用，包括培训技术和听力工作人员，现场确定AEP和OAE设备的充分性，测试听力测量设备的整体性能和校准，以及研究和开发应用。此外，还将汇集与正常听力和各种类型的听力损失相对应的AEP和OAE反应的完整资料库，从而能够模拟各种情况。在第一阶段，由智能听力系统公司开发的基于数字信号处理器的硬件平台将进一步改装，用作模拟器。将开发软件对各种类型的声刺激进行检测和分类，并输出相应的响应。基准测试和模拟将使用来自不同制造商的AEP和OAE测试设备进行。 拟议模拟器的使用可望改善操作员培训并使其标准化，并减少与各种听力测量设备有关的设备或操作员问题。预计这将通过改善使用听力测量设备的医务人员提供的服务质量来影响公众健康。

DESCRIPTION (provided by applicant): The development of a comprehensive hearing simulator is proposed. The simulator will be able to receive acoustic stimuli and output the corresponding auditory evoked potentials (AEP) and otoacoustic emissions (OAE). The simulator will have a broad range of applications including training of technical and audiological staff, determining the adequacy of AEP and OAE devices on-site, testing overall performance and calibration of hearing measurement devices and research and development applications. In addition, a complete library of AEP and OAE responses, corresponding to normal hearing and various types of hearing losses will be assembled, allowing simulations of a wide range of conditions. During Phase I, a DSP-based hardware platform, developed by Intelligent Hearing Systems, will be further modified for use as a simulator. Software will be developed to detect and classify various types of acoustic stimuli and output the corresponding responses. Benchmark testing and simulations will be performed using AEP and OAE testing equipment from various manufacturers. The use of the proposed simulator is expected to improve and standardize operator training and reduce device or operator-related problems associated with a wide range of audiometric equipment. This is expected to impact public health by improving the quality of services provided by medical personnel using audiometric equipment.
