Advanced DSP-Based Hearing Simulator

描述（由申请人提供）：提出了一种综合听力模拟器的开发。该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）。该模拟器的应用范围广泛，包括培训技术和听力学人员、现场确定听觉诱发电位和耳声发射设备是否足够、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，还将组装一个完整的AEP和OAE响应库，对应于正常听力和各种类型的听力损失，允许模拟各种条件。在第一阶段，智能听力系统开发的基于DSP的硬件平台将进一步修改，用作模拟器。将开发软件来检测和分类各种类型的声学刺激，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。 使用拟议的模拟器，预计将改善和标准化的操作员培训，并减少设备或操作员相关的问题与广泛的听力测量设备。预计这将通过提高医务人员使用听力测量设备提供的服务质量来影响公共卫生。

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.
