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，还将组装与正常和各种类型的听力损失相对应的AEP和OAE反应的完整库，从而能够模拟各种情况。给出了第一阶段的结果，表明了项目的可行性。在第二阶段，将对该项目的机械、电气和软件部分进行工作，包括使用新生高分辨率CT图像来建造模拟器耳朵结构。基准测试和模拟将使用来自不同制造商的听力测试设备进行。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 and various types of hearing losses will be assembled, allowing simulations of a wide range of conditions. Phase I results are presented showing the feasibility of the project. During Phase II, work will be conducted on mechanical, electrical and software components of the project, including the use of newborn high resolution CT images to construct the simulator ear structures. Benchmark testing and simulations will be performed using hearing 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.
