HIGH FREQUENCY SUPPLEMENT FOR PROFOUNDLY DEAF PEOPLE

这项工作的重点是开发一种具有触觉的助听器 高频语音能量的显示。联合援助将 集成调频接收器，目标是严重到深度失聪 有明显低频听力，但听力很低或没有听力的人 获取高频语音提示。初始阶段将建立 高频光谱特性数据库 具有代表性的成年和儿童男性样本产生的辅音 和女性演讲者。然后，这些信息将用于设计一个 通过触觉区域呈现高频辅音的系统。 这将通过一系列可控震源来实现，允许用户 准确地检测和区分高频集合 辅音。拟议的工作包括实验室评估 用于确定哪个阵列可通过以下方式实现最佳性能的原型阵列 一组聋人受试者。然后，将结合电传建造一个辅助设备 TDR 40系统用于听觉/调频信号和我们自己的触觉显示。 然后，两名聋人受试者将使用该实验进行训练和测试 系统。在Il阶段，将设计并广泛提供商业援助 制定了培训程序。 建议的商业应用： 如果这项工作成功，将导致一次联合听证会 辅助功能！内置调频接收器的触觉辅助功能。这种类型的设备将 允许严重和深度失聪的受试者获得高范围的 频率辅音。一体机将大大减少 实现这一目标所需的设备数量。

This work focuses on the development of a hearing aid with a tactile display of high frequency speech energy. The combined aid will incorporate an FM receiver and is aimed at severely to profoundly deaf people with significant low frequency hearing, but with little or no access to high frequency speech cues. The initial phase will establish a data base of the spectral characteristics of the high frequency consonants produced by a representative sample of adult and child male and female speakers. This information will then be used to design a system to present the high frequency consonants via the tactile domain. This will be achieved via an array of vibrators allowing the user to accurately detect and differentiate between the set of high frequency consonants. The proposed work includes the laboratory evaluation of prototype arrays to determine which one allows the best performance by a panel of deaf subjects. An aid will then be built combining the Telex TDR 40 system for the auditory/FM signal and our own tactile display. Two deaf subjects will then be trained and tested using the experimental system. In Phase Il a commercial aid will be designed and extensive training procedures developed. PROPOSED COMMERCIAL APPLICATION: If this work is successful it will result in a combined hearing aid!tactile aid with a built in FM receiver. This type of device would allow severely and profoundly deaf subjects access to the range of high frequency consonants. An all-in-one device would greatly reduce the amount of equipment needed to achieve this aim.
