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.

描述（由申请人提供）：建议开发综合听力模拟器。模拟器将能够接收声刺激并输出相应的听觉诱发电位（AEP）和耳声发射（OAE）。该模拟器将具有广泛的应用，包括培训技术和听力人员、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发应用。此外，还将组装一个完整的 AEP 和 OAE 响应库，对应正常听力和各种类型的听力损失，从而可以模拟各种条件。在第一阶段，由智能听力系统公司开发的基于 DSP 的硬件平台将被进一步修改以用作模拟器。将开发软件来检测和分类各种类型的声刺激并输出相应的响应。基准测试和模拟将使用不同制造商的 AEP 和 OAE 测试设备进行。 使用所提出的模拟器预计将改善和标准化操作员培训，并减少与各种听力测量设备相关的设备或操作员相关问题。预计这将通过提高使用听力测量设备的医务人员提供的服务质量来影响公共健康。
