Core--Engineering

数字信号处理（DSP）技术是现代听觉研究不可缺少的技术。实时信号处理对于人工耳蜗、助听器和感觉替代设备的语音处理器至关重要。电生理学（ABR）和耳声发射（OAE）研究需要实时处理，以研究商业ABR和OAE设备或便携式测试设备之外的技术。生物 动态过程的测定可能需要实时图像处理以在毫秒时间尺度上区分细胞机制。DSP硬件和软件是复杂且快速发展的技术，需要更高级别的工程资源，通常比任何一个研究应用都要合理。该工程核心提案将支持开发、维护DSP技术并将其集成到 目前，在HEI的研究项目。该核心提出了两个层次的工程支持：专业的DSP专业知识和一般工程服务。Specific Aim 1将在最新的硬件和软件平台上开发和维护DSP专业知识。工程核心将开发具有相关软件操作系统的核心DSP硬件平台， 允许研究人员从PC或基于MAC的实验室机器下载程序到DSP平台，并控制数据流和处理DSP系统的错误。具体目标2将允许工程核心人员与项目特定工程师进行交互， 为各个项目的输入传感器和输出执行器提供专用硬件和软件。传感器可以包括振动传感器、声学传感器、光子传感器、生物传感器或电传感器。致动器可以包括声学、振动、电气或数字植入物传输代码。具体目标3将为核心研究者提供标准声学测试设备的工程支持，如听力计、商用ABR和OAE测量设备以及心理物理测试设备。工程核心将协助配置、维护和校准这些设备。

Digital Signal Processing (DSP) technology is indispensible for modern auditory research. Real-time signal processing is essential for speech processors for cochlear implants, hearing aids, and sensory substitution devices. Electrophysiology (ABR) and otoacoustic emissions (OAE) research requires real-time processing for research on techniques that are outside the realm of commercial ABR and OAE devices, or for portable test equipment. Biological assays of dynamic processes may require real-time image processing to differentiate cellular mechanisms on millisecond time scales. DSP hardware and software are complex and rapidly evolving technologies that require higher-level engineering resources than can usually be justified by any one research application. This Engineering Core proposal would support the engineering expertise necessary to develop, maintain, and integrate DSP technology into the existing research projects at HEI. This core proposes two levels of engineering support: specialized DSP expertise and general engineering services. Specific Aim 1 will develop and maintain DSP expertise on the latest hardware and software platforms. The Engineering core will develop core DSP hardware platforms with associated software operating systems, which will allow investigators to download programs into the DSP platform from PC or MAC-based laboratory machines and control data flow and handle errors from the DSP system. Specific Aim 2 will allow Engineering Core personnel to interface with project-specific engineers to develop specialized hardware and software for input sensors and output actuators for the individual projects. Sensors might include vibratory, acoustic, photonic, biosensors, or electrical. Actuators could include acoustic, vibratory, electrical, or digital implant transmission codes. Specific Aim 3 will provide Core Investigators with Engineering support for standard acoustic test equipment, such as audiometers, commercial ABR and OAE measurement equipment, and psychophysical test equipment. The Engineering Core will provide assistance in configuring, maintaining and calibrating such equipment.
