本文讨论了一个基于个人数字助理（PDA）的人工耳蜗研究平台的设计、开发、特性以及临床评估。这个高度通用且便携的研究平台使研究人员能够极其轻松灵活地设计并执行针对科利耳公司生产的人工耳蜗的复杂实验。该研究平台包括一个用于实施和评估新型语音处理算法的便携式处理器，一个可用于对动物进行电刺激和神经生理学研究的刺激器单元，以及一个用于从人类受试者收集脑电图/诱发电位的记录单元。针对纯电刺激以及电加声刺激模式，讨论了该平台实时和离线刺激模式的设计，接着给出了在安静和嘈杂条件下对植入使用者进行的语音清晰度急性研究的结果。这些结果与使用者的临床处理器相当，对于进行慢性研究非常有前景。
This paper discusses the design, development, features, and clinical evaluation of a personal digital assistant (PDA)-based platform for cochlear implant research. This highly versatile and portable research platform allows researchers to design and perform complex experiments with cochlear implants manufactured by Cochlear Corporation with great ease and flexibility. The research platform includes a portable processor for implementing and evaluating novel speech processing algorithms, a stimulator unit which can be used for electrical stimulation and neurophysio-logic studies with animals, and a recording unit for collecting electroencephalogram/evoked potentials from human subjects. The design of the platform for real time and offline stimulation modes is discussed for electric-only and electric plus acoustic stimulation followed by results from an acute study with implant users for speech intelligibility in quiet and noisy conditions. The results are comparable with users’ clinical processor and very promising for undertaking chronic studies.
